Fix Error 0x800F0923 in Windows 10

Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:

"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"

In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Solution

Error Causes

There are multiple reasons for this error message including:

• The email address was typed incorrectly
• Incorrect SMTP Server settings
• ISP placing restrictions for outgoing mails on the email server
• System infected by virus or malware

Further Information and Manual Repair Regardless of what the reason may be for the error 550 code occurrence, it is advisable to repair and fix the issue quickly to avoid inconvenience. You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error. This can be done by opening your Outlook settings Tools and Accounts option. Now go to view/change the email account for the email account you are having problems with. After that check, the SMTP server is set to mail.yourdomain.com. Then click more settings and then click the outgoing server tab. See if the ‘My server requires authentication for the outgoing server’ is checked. If not, then check on it. Then simply save to confirm changes. Now try emailing again. Hopefully, this will resolve the issue.

Solution 3:

Another reason for the error occurrence can be ISP blockage. When the junk email volumes increase, network administrators (the people who are responsible for managing ISP servers) place restrictions on SMTP email servers to prevent spam on their network. If this is the reason, contact your ISP administrator to resolve the issue.

Having a PC is a great thing, more often we are enjoying it than we have issues, but as time passes it seems that our computer is slowing more and more as new applications and games are coming which demand more powerful computers. Before you decide to throw away your computer and buy a new one because you feel it is a bit slow, read through this guide where we will guide you to common tips & trick to make your PC run faster:

1. Keep your PC clean and tidy

   Slowdowns and many other issues, even hardware failures can come from dirty PC. Make sure your PC is clean and tidy for maximum performance.

2. Optimize airflow through PC casing

   Airflow is very important so your GPU and CPU and overall all hardware components can be kept in optimal working temperatures. If any device inside the casing is working in abnormal temperatures you will experience slowdowns and freezing on daily basis. Make sure that all fans are working and that your temperatures are in the optimal range to prevent overheating and make sure to have maximum performance.

3. Check PC for malware

   Viruses, worms, and overall all malware can drastically reduce system performance. Make sure that your protection software is up to date with the latest definitions and that you have the latest Windows updates installed.

4. Create a Hi-Performance power plan

   Windows power plans can be a very useful feature, especially if you are working on laptop but in order to boost performance and drain maximum, you will need to switch to a hi-performance power plan.

5. Free space on the system drive

   Having little to no space on your Windows system drive can lead to extreme slowdowns, make sure that your hard drive is not on red when viewed from File explorer or you will experience even 50% poorer performance.

6. Choose startup applications

   If you have many applications starting up with your Windows and many of them running in the background you will experience performance issues. Each application that runs in the background is taking RAM and CPU time for themselves which could be free and used for the program that you need.

7. Do not open too many tabs in Browser

   Having too many tabs in Browser while working on a computer can also cause slowdowns, each tab is taking RAM for itself and even can cause Browser poor performance if a tab is LIVE and refreshing with new content all the time.

8. Remove browser extensions

   Speaking of browser, having too many installed extensions which are active as soon as the browser is up and running can also lead to poor performances. Remove all which you really do not need and your computer will gain in speed.

9. Make hardware upgrade

   Sometimes your system is just a little outdated, upgrading more RAM or switching to a new SSD with the greater speed can cause a world of difference in PC performance. Check to see how RAM is standard and upgrade accordingly, you can also upgrade the CPU and other bottlenecks in your system this way instead of completely buying a new PC.

10. Format and reinstall system

    Drives, application traces, registry entries, etc. are piling up in your system over time, and if enough time is given it will clog your computer. From time to time it is a good idea to backup files and do a completely clean full format of HD and install a new and fresh copy of Windows with new and clean copies of applications and drivers.

That's it, 10 tips on how to make your Windows and PC perform better and speed it up. I hope that you found the read informative and helpful and I hope that I will see you soon.

Windows 10 users a set of rules or standards called Network Protocols in communicating over the internet. These protocols are the ones that made sure that the data is correctly sent between computers. However, if any of the Network Protocol is missing in your Windows 10 computer, then you will most likely encounter a problem like not being able to browse the internet, or share files. For this, you can try to run the Incoming Connections troubleshooter: As you were not able to connect to your internet connection using your PC, you can try to run the Incoming Connections troubleshooter as it might resolve the problem. Refer to the following steps to run this troubleshooter:

• Tap the Win + I keys to open Settings.
• After opening Settings, go to Update and Security.
• Next, navigate to the Troubleshoot pane and select the Incoming Connections section and click the Run Troubleshooter button to get started.
• Wait until the troubleshooter is finished doing its job and then try connecting to your network again.

If after running the Incoming Connections troubleshooter you receive an error message instead that says, “Network Protocol is missing”, then here are some suggestions you need to check out to fix it. Take note that you must have admin privileges before you start troubleshooting the problem.

Option 1 – Try to update or rollback or uninstall the Network drivers

You might also want to update, roll back, or disable your Network drivers to fix the “This operation failed as no adapter is in the state permissible for this operation” error.

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and depending on your preference, you can either select “Update driver”, “Disable device” or “Uninstall device”.
• After that, restart your PC and see if it helped in fixing the netio.sys Blue Screen error.

Option 2 – Try to reset Winsock, TCP/IP & Flush DNS

You might also want to try resetting Winsock, TCP/IP, and flushing DNS might help you resolve errors. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 3 – Diagnose the Network Adapter

To diagnose the Network Adapter, go to Control Panel > All Control Panel Items > Network Connections, and from there, look for the network adapter that could be causing the error. Note that if you are using a Wi-Fi connection, then it’s probably your Wi-Fi adapter, otherwise it has something to do with your Ethernet adapter. Just right-click on the problematic network adapter and select diagnose to troubleshoot.

Option 4 – Try to perform Network Reset

You can also try to perform a Network Reset to resolve the problem. This will reset the entire network configuration including your IP address. To perform Network Reset, follow these steps:

• Tap the Win + I keys to open Settings.
• From there, go to the Network and Internet section.
• Next, scroll down and look for “Network Reset” under the status pane.
• After that, click on Network Reset and then on Reset now to start resetting the network configuration. Once done, check if it is able to fix the error or not.

Option 5 – Try importing Winsock settings from another computer

If resetting Winsock or the Network didn’t fix the problem, then you can try to import settings from a computer that’s in good condition. You need to have access to the registry to get this done and then export and import a couple of settings. Refer to these steps to get started:

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, go to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices
• Next, look for two registry keys named “Winsock” and “Winsock2” and then right-click on each one of them and select the Export option.
• Now copy the registry keys to a USB drive and then copy the keys on the PC in excellent condition.
• Then double click on each one of them and it will install the WINSOCK keys.

Mac OS

A solid reason to switch to Mac from Windows PC is Mac OS. Based on Linux, offers more stability and better security than Windows but you will not be able to find a vast array of applications on it.

Even when Mac OS X (the first big one) was first introduced, it looked and felt like ages beyond Windows (Microsoft just recently made a slick and modern design with Windows 11). Under the hood, it turned out that the operating system itself is stable and incredibly fast & responsive. If you value stability and easiness of use, Mac OS is the Operating system for you.

Apple ecosystem

This one is easy, if you are already invested in apple devices like iPhone and iPad, having an apple computer is one step forward into the apple ecosystem and one more step into easy sharing of documents and data between devices.

Calendars, emails, photos, videos, documents, and many more can easily be shared and synched between devices with a single apple ID making workflows much easier than on other operating systems.

Development

Developers all around the world say that developing on Mac is much better and smoother than on PC, this has probably to do something with OS being based on Linux but whatever the case is, it is much smoother and it just feels better. Apple laptops are often the go-to choice of developers for a reason.

Also if you are in the development business for applications and services aimed at iPhone or iPod then there is no really another way than to be into the apple ecosystem and own apple hardware.

Professional software

A lot of professional-grade software exists for both the Windows platform and Mac OS but there is some software that exists exclusively for Apple hardware like Final Cut Pro or Logic Pro. Both applications are used by professionals and are industry-standard software.

Logic pro is used by industrial audio specialists all around the world and is used in professional studios. Final Cut Pro is also used worldwide by video editors and if you are specializing in any of these two fields Mac seems like a very reasonable platform since the software can not be found on Windows. These two are examples, there are other similar applications that are only available on Mac OS

Longevity

Apple hardware is made of high-quality materials and components and it is proven over time that it lasts longer than usual. There are iPhones out there that have 13 years and they are still working, G3 and G4 Macs that are still functional.

When buying Apple products they will outlive other ones if treated properly so in the end you could be saving money by purchasing them.

Having an eMail in today's modern world is no longer a privilege or being geeky, it has surely become a necessity. From Facebook to LinkedIn or Steam many services today require you to have an account in order to use them, and in order to create an account, you need working eMail. That being said many people today have several eMail accounts, one for social media, one for work, maybe even one for very close friends and family. How creating eMail today is completely free we might end up with several eMail accounts. eMail clients have also evolved much since their first days and became more than just applications for receiving eMails, today they can take various different tasks having additional features built into them like calendar, batch eMail processing, etc. Taking all of said into account I am presenting to you within my personal opinion some of the best eMail clients starting with free ones.

Best free eMail clients

Google Gmail

https://gmail.com It would be very difficult to even start a free eMail list without mentioning Google's Gmail. Introduced all the way back in 2004 as an invite-only service it became over time the most popular email platform largely due to the fact Google is offering free eMail accounts. There are a lot of good things to be said about Gmail itself, most of the area is clutter-free and the largest space is reserved for eMail itself letting users focus on what is important. WEB client itself means that you do not need to have any application installed on your device, altho via Google chrome, you can use Gmail offline offering you flexibility if needed. The ability to connect and manage other accounts like Outlook, Yahoo, etc is just making Gmail even more attractive, and the snooze feature is a really neat little detail that will pause eMail notifications if you need to focus on other things. Lack of organizing messages into folders is a little confusing since Gmail offers its own unique label system but sometimes I need to have old reliable save eMail to folder. All in all, Gmail is a great service and it offers a great eMail on the go experience.

Mail eMail client

https://www.microsoft.com/en-us/p/mail-and-calendar/ Free Windows eMail client simply called Mail is what was once outlook express. Mail itself has the ability to work with other popular accounts like Google Gmail account, Yahoo, iCloud etc. How it comes with Windows OS and it integrates very well with Microsoft Calendar, this eMail client is for many the first choice. On the negative side, I might say this is a strip-down version of Outlook which is paid solution so some features are missing if we would compare the two. Overall, a simple and nice eMail client worth your time, especially if you are on the Windows platform.

Mozilla Thunderbird

https://www.thunderbird.net Great eMail client matching in functions against paid and premium solutions of big tech companies. Fueled with plenty of customization options and reskinning ones this eMail client offers a lot for its free price tag. It is also fueled by Mozilla community focusing on privacy and security. It can work with any mail service and it is lightweight with a clean look, altho the look itself can be heavily customized. The bad side is that client itself relies on email services to provide cloud-based emails, so if you are receiving your email via a service that does not have a cloud-based service in itself all of your received emails will be locked to the computer where you have received them. Also customizing it can be sometimes a little too technical for the average computer user. All in all, Thunderbird is one great eMail client and it would be a shame not to use it because of its technical side, if you need a reliable and secure eMail client on a single machine, look no further than Thunderbird.

Paid eMail clients

Microsoft Outlook

https://www.microsoft.com/en-us/microsoft-365/ Outlook comes as a part of the Microsoft Office suite and as one of the oldest eMail clients, it is still widely popular and adopted through many users and businesses. It has tight integration with all Microsoft services and full integration with Calendar making it one of the if not the best eMail client out there. Outlook also has a free online service completely free for personal use as well. The downside is that you can not get it as a separate product if you want a business version other than as a part of the Office suite. The final verdict would be that this is perhaps the best eMail client out but the big downside is that there is no desktop version outside the Office suite.

eM Client

https://www.emclient.com/ eM Client offers a wide array of features, including a calendar, contacts, and chat. Support is provided for all the major email services including Gmail, Yahoo, iCloud, and Outlook.com. The latest version also offers PGP encryption, live backup, basic image editing capabilities, and auto-replies for Gmail. Its automatic system makes it very easy to get emails from other services since there is no manual setting, all that is needed is to type in your email and eM Client will do everything else automatically. A one-time purchase is not pricy and it could offer some features that some free clients are missing. Go check it out with a free trial and see if it is for you.

Mailbird

https://www.getmailbird.com This eMail client's main focus is the simplicity of use with visual appeal while tackling multiple eMail accounts. It has many built-in apps along with a customizable interface. Unlike some more Microsoft-centric email clients, Mailbird Business supports a diverse range of integrated apps, including WhatsApp, Google Docs, Google Calendar, Facebook, Twitter, Dropbox, and Slack, all making for a better-streamlined workflow. The downside of this client is the yearly subscription plan. I think people, in general, want to get away from software subscription plans so I will include this as a downside but bear in mind it is downside just in terms of a business plan not in the client itself.

Inky

https://www.inky.com/ Inky is eMail client if you are looking for security. It uses AI along with machine learning in order to block all types of phishing attacks that can get through to other clients. The proprietary machine learning technology can literally read an email to determine if it has phishing content, and then is able to quarantine the email or deliver it with the malicious links disabled. It also takes things a step further and offers an analytics dashboard, which allows an administrator to see patterns of attacks based on dates, or targeted users. The downside is that client itself is so much focused on security that sometimes some nonsecurity features get overlooked and provide a poor experience but if you need a good and greatly secured eMail client Inky is one to check out.

Browsing your files on a computer seamlessly is made possible by the File Explorer in Windows 10 as it provides users with a great sense of customization for both listing and performing operations on a file. You have the option to arrange the folders and files being browsed by their name, type, date, size, and so on. Moreover, files that share a common attribute can be also be grouped accordingly using the grouping feature. However, there are times when instead of helping, it causes some problems for some users. This is why in this post, you will be guided on how you can disable the File Grouping feature in the File Explorer in Windows 10. There are two methods you need to consider in disabling the File Grouping feature in Windows 10. First, you can disable it for only one folder or you can disable it for all the folders on your computer. For more details, follow the instructions given below.

Option 1 – Disable File Grouping in only one folder

This first option is relatively straightforward and simple which will work if you only want to disable File Grouping in one folder.

• First, open File Explorer, and go to the folder you want to disable File Grouping.
• Next, right-click anywhere on that folder.
• And then select Group by > None. This will disable File Grouping for only that particular folder.

Option 2 – Disable File Grouping in all the folders

If you wish to disable File Grouping in all the folders on your computer, then you need to follow this option. If you have already tried the first one, then continue with the given steps below.

• Tap the Alt + V key combination.
• Then tap the Alt + Y keys and then tap Alt + O keys.
• After that, navigate to the View tab, and under the Folder views section, select Apply to Folders.
• Now click on the Apply and OK buttons to save the changes made. This will disable File Grouping in all the folders listed in the File Explorer.

In case you don’t know, there is a feature in Windows 10 computers that allows them to function a lot better. This feature is called Full-Screen optimization and it is enabled by default for several applications such as games and video players. If enabled, the Full-Screen optimization feature enhances the video playback and gaming by simply putting the CPU and GPU process as a priority. However, there are times when it can also result to a drop in the frame rate or FPS while in full-screen mode. And of course, the obvious solution to this dilemma is by disabling the Full-Screen optimization feature which is why Microsoft took action and removed this feature themselves in the recent Windows 10 Update releases. However, there is another way for you to enable it back or disable it yourself if you haven’t installed the recent updates yet and there are plenty of ways you can do both. All you have to do is follow the options given below carefully.

Option 1 – Try using Windows 10 Settings

If you haven’t installed the recent updates yet and all you have are the earlier releases, then this method would suit you.

• Open the Windows 10 Settings app.
• Next, navigate to System > Display > Graphics Settings or Advanced graphics settings.
• From there, uncheck the “Enable Fullscreen optimization” option if you want to disable the feature, else just keep it checked.

Option 2 – Try using the Registry Editor

• Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Afterward, if a User Account Control or UAC prompt appears, click on Yes.
• Once the Registry Editor is pulled up, navigate to this registry key: HKEY_CURRENT_USERSystemGameConfigStore
• Next, right-click on Explorer and select New > DWORD (32-bit) Value and then name it to “GameDVR_DSEBehavior and tap Enter to save it.
• Now double click on the newly created GameDVR_DSEBehavior DWORD and set its value to “2” if you want to disable it, or “0” if you want to enable it.
• Once you entered the value, close the Registry Editor and restart your computer to successfully apply the changes made.

Option 3 – Try running the application in Compatibility Mode

If the first two options didn’t work, the next thing you can do is to run the application in a Compatibility Mode. Follow the steps below to do so:

• Go to the location of the application or game on which you need to disable or enable the Full-Screen optimization feature.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you can see the “Disable fullscreen optimization” option to disable the feature and vice versa.
• Now click on the Apply and OK buttons to apply the changes made in the application’s settings.

When performing a Windows Backup to the NAS device (backup to a network share) that is running Samba, fails with an error message The backup failed, The version does not support this version of the file format (0xC03A0005). The problem occurs because of a conflict with the VHD file that is created by Windows Backup and is mounted during the process. There are three types of VHD files:

1. Fixed,
2. Expandable
3. Differencing

If the VHD file is a sparse file that is not supported by the native VHD driver, the mounting will fail, and you will get this error. An example VHD file is one that keeps expanding depending on the backup size. The problem occurs only in the case of  File Level backup (file/folders in a volume) but not on the block level backup as the vhd file is never mounted. However, in the case of File Level Backup, the vhd is mounted, created by Windows Backup, which does not support the mounting of sparse files.

The solution is to use Strict Allocate: option in the smb.conf file

Login to SMB using SSH. Open the configuration file using the VI editor located at /etc/samba/smb.conf. If the option is not there, you can manually add strict allocate = yes which will make sure there are no sparse file that is created.
