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.

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.

There are times when after you upgrade your Windows operating system, the System Logs under the Event Viewer will display an error message saying, “Event ID 10010 error – The server did not register with DCOM within the required timeout”. What is DCOM? DCOM stands for “Distributed Component Object Model”. It is a proprietary Microsoft technology that allows the Component Object Model or COM software to communicate across a network. You can consider it as an extension of COM which is equipped with the capability of solving a couple of inherent problems related to the COM model to the better use over a network. COM is a tool that’s used for advanced configuration and troubleshooting in Windows 10. Developers usually use it to configure routine components and application behavior like participation in transactions and object pooling and so on. The Component Services needs the DCOM wire protocol in order to communicate with the Component Object Model components on other computers. By default, in a Windows-based system, the network computers are configured initially to enable DCOM. There are also some components in Windows that might require registering themselves with DCOM. However, if they fail to do so, you will encounter the “The server did not register with DCOM within the required timeout” error. To fix this, here are some suggestions you can check out.

Option 1 – Try to use the Component Services

• Tap the Win + R keys to open the Run dialog box.
• Then type “dcomcnfg” in the field and tap Enter to pull up Component Services.

Pinned Windows 10 Taskbar Items. One of the most used interfaces in the Windows environment is the Taskbar. It is where users like to pin their most-used programs as well as shortcuts with extra privileges and automated tasks. In fact, it’s a lot better than the Start Menu. So if any Windows Update messes up with your computer, or if you’ve just switched to a different computer, setting up the Taskbar with the very same set of programs you used to have is definitely not an easy task. But worry not as this post will guide you on how you can backup and restore the items on your Taskbar either manually or automatically.

Manual Backup:

• Tap the Win + R keys to open the Run prompt.
• Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the folder where you can see all the shortcuts or pinned items in the Taskbar.
• After that, copy all the files in the folder and paste them somewhere else as a backup. For instance, E:\Pinned Items Backuppinnedshortcuts.
• Next, tap the Win + R keys to open the Run prompt once more, and then type “Regedit” in the field and hit Enter to open the Registry Editor. When the User Account Control dialog box appears, click Yes.
• After opening the Registry Editor, navigate to this key – HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband
• Then right-click on the Taskbar folder and select Export.
• Now save the file with the .reg extension to another location like the E:\Pinned Items Backup folder and then name it.
• Close the Registry Editor.

Manual Restore:

Make sure to copy all the files to one of the drives if you are using another computer and then refer to the following steps.

• Tap the Win + R keys to open the Run prompt.
• Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the same folder where you just copied all the shortcuts. Make sure to keep it open.
• Then open the backup folder where you saved all the pinned items and copy all the files there.
• Next, go to the Taskbar folder (%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar) and then paste your files in there. If you encounter a problem while doing so, just replace it with your own set of files.
• After that, go to E:\Pinned Items Backuppinnedshortcuts and then double click on tb-pinned-items.reg. If a User Account Control prompt appears, click Yes. This will add the registry file into the main registry hub. You will also get a dialog box that will confirm that data has been added to the registry successfully. Click OK.
• You should now see the items on the Taskbar. You have to restart Windows Explorer. To do so, end its process in the Task Manager.

Automatic Backup:

Backing up and restoring the pinned Taskbar items in your Windows 10 computer can be done automatically as well. But before you get started on the process, you need to understand what’s going on behind the hood first. First, you need to create two bat files and name them “Backup Pinned Taskbar Items” and “Restore Pinned Taskbar Items”. After you have that covered, refer to the following steps:

• Open the Notepad app and paste the following details and save it as “Backup Pinned Taskbar Items.bat.

REG EXPORT HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband “E:\Pinned Items Backuptb-pinned-items.reg” xcopy “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” “E:\Pinned Items Backuppinnedshortcuts” /E /C /H /R /K /Y

• After that, run the newly created bat file with admin privileges.

Automatic Restore:

• Open the Notepad app and paste the following details and save it as “Restore Pinned Taskbar Items.bat”.

REGEDIT /S “E:Pinned Items Backuptb-pinned-items.reg” xcopy “E:Pinned Items Backuppinnedshortcuts” “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” /E /C /H /R /K /Y

• After that, run the bat file with admin privileges.

Note: Just so you know, there is a drawback to this process as we’ve noticed that any pinned apps that were downloaded from the Windows Store don’t appear in these places and any items downloaded and installed separately from the internet and then pinned.

Ever gotten an e-mail offer that seemed just a little bit too good to be true? Might’ve been a phishing attempt! These are everywhere and can come in many different forms. 

So what’s phishing exactly, how can you detect it and how can you keep safe?

What is phishing?

Phishing (pronounced like fishing) is a type of cyberattack that tricks the user into trusting the source and revealing sensitive information. Fishing being the perfect analogy, the bait is a legitimate-looking site, e-mail or file and when you take a bite, your identity, banking information and much more can be revealed and stolen.

Some phishing attempts are incredibly obvious, others are super elaborate. Like with most types of malware, cybercriminals have become extremely well-versed in phishing and anyone can fall for it. To help you recognize and avoid it, we’ll take you through a couple of phishing types and give you tips on what to do if faced with them.

Phishing techniques

E-mail phishing

This is actually the most common type of phishing. A cybercriminal creates an e-mail containing stuff like attractive offers, legitimate-looking attachments or links and makes it appear as though it’s coming from a trusted source.

For example, it looks like it’s coming from your bank or your favorite retailer. The logo looks legit and the structure of the e-mail seems familiar, so you might get tricked into clicking on whatever clickable content is in it.

Unfortunately this exposes your device to malware that hands your data off to the hacker, who can decide what to do with it further.

SMS and social media phishing

Like the above example, you could be approached with lucrative offers or links via text messages or social media messages. Typically, the messages seem relevant to the user as they will be made to look like they’re related to apps or services you’re using.

Voice phishing

Voice phishing attacks are schemes that appear as though they’re coming from a credible number. Normally, you’ll get a call about something related to credit cards or taxes to get you into a state of worry, leading you to disclose personal information on the phone.

Spear phishing, whaling and BEC

Spear phishing normally targets specific individuals within a company who are likely to have access to sensitive data. Spear phishers spend time collecting information they can use to reach out to the individual looking as trustworthy as possible. They’ll typically lead with something relevant, for example mentioning an upcoming company event, and make a seemingly legitimate request.

Whaling is a more elaborate form of spear phishing, which targets people in even stronger positions such as executives or high-value individuals. The ultimate goal is to get them to transfer financial or other sensitive information that can be used to compromise the entire business.

BEC, or Business e-mail compromise, is a specific spear phishing technique carried out via e-mail. While there are many ways this is done, most commonly you’ll see instances where the phisher poses as a CEO or similar executive, or as a lower-level employee in specific positions (e.g. sales managers or financial controllers).

In the first situation, the impersonator reaches out to employees requesting them to transfer certain files or pay invoices. In the second situation, the phisher takes control of the employee’s e-mail account and sends false instructions to other employees in order to obtain data and information from them.

What can you do?

There are many ways you can be aware and spot a phishing attempt. Here are some tips:

• Always check the sender’s address in your e-mails, even when they seem to come from a familiar source.
• In any instance where payment information is requested, be very, very careful.
• If you are receiving attachments you never asked for and definitely didn’t expect, better not click on them. 
• Beware of content that transmits a sense of urgency (sales deals, urgent updates to login credentials, etc.).
• Bad spelling and grammar are usually a telltale sign of phishing.
• Links that look shortened (e.g. Bit.ly) or just suspicious in general - if you have a bad feeling, do not click on them.
• If you are receiving threats, you probably shouldn’t be clicking on anything in that message.
• Always examine first-time senders in detail.
• Block suspicious e-mail addresses, numbers and social media accounts.
• If you are receiving a coupon for free stuff… You aren’t.
• If you’re being asked to update your payment details by a service you use, such as Netflix, chances are it’s an impersonator.

Those are some of the ways to identify and prevent phishing attacks. However, sometimes phishers disguise themselves a little too well or a misclick happens and there you go - you’ve been exposed to malware.

This won’t happen if you invest in powerful protection software from the get-go, though. A good antivirus program like Bitdefender will keep you safe from becoming a victim of phishing scams. In fact, it will protect you from malicious attacks overall.

Be it your household or your business you’re concerned about, there are a bunch of different packages and options available, providing different kinds of cybersecurity services. That’s the only way you can ever really be sure you aren’t at risk of a digital attack.

Summary

Have you ever been targeted by phishers and didn’t know that’s what it was until you read this article? Many can relate. Protect yourself before it’s too late!

Microsoft starting as of today will block its Office 365 users if they are using Internet Explorer or early versions of Edge browsers. So if you are using older non Chromium Edge versions of Microsoft browsers you can no longer access Office services until you switch. Now normally I would fully support this kind of decision since Internet explorer is a slow and vulnerable browser and the edge is similar in that regard. The new edge browser is great and it should be used but the issue I have is that Office 365 is not free, it is a premium feature and I am wondering how Microsoft plans to deal with people that have already paid for service but suddenly cannot access it anymore.

If you connected headphones to your Windows 10 computer to listen to audio but when you check it in the playback devices, you’re not able to find it, read on as this post will guide you in what you can do to figure out what exactly caused this kind of problem and how you can resolve it. This kind of issue could simply be with the headphone itself or the headphone port or your operating system. So if it turns out that the problem is with the hardware, you might have to replace the components. However, it is recommended that you troubleshoot the problem first before doing that. The most basic thing you can do is to try changing the headphone port, although this can be quite difficult since most computers don’t have any extra port for headphones if your computer has one, then give it a go. If it still didn’t work, follow each one of the options provided below.

Option 1 – Try to run the Playing Audio troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to update the Audio driver

If the error has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.
• Expand the section of the Audio inputs and outputs.
• And then from the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.
• Then also click on the option, “Search automatically for updated driver software.
• Restart your PC after the installation.

Note: If updating the Audio driver didn’t work, you can go to the website of your PC manufacturer and look for the support section where you can download the drivers for your computer. You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 3 – Try enabling the headphones from the playback devices

• Tap the Win + R keys to open the Run dialog box and type the “CPL” command.
• Tap Enter to open the Playback devices.
• Next, right-click on any open space section and check the boxes for the “Show Disconnected Devices” and “Show Disabled Devices” options.
• After that, this should help in displaying the headphones in the section of Playback devices.
• And if they are disabled, you can just right-click them to have them enabled.

System image backup error 0x807800A1 & 0x800423F3 appears when you are trying to create a system image backup and the operation fails to do so. If you’re faced with any of these error codes, try our recommended solutions in the order presented below and resolve the issue.

Check Volume Shadow Copy & Software Protection Services

To restart the Volume Shadow Copy Service (VSS) on Windows 10, do the following:

• Press ⊞ Windows + X to bring up the Windows menu.
• Click on command prompt (admin)
• In the command prompt window, type the commands below and hit Enter after each line:

net stop vss net start vss

Once the commands execute successfully, try the system image backup again. The operation should complete successfully. You need to also check if the Software Protection Service is disabled. If it is, then Start it and ensure that it is set to default which is Automatic (Delayed Started).

Create System Image using PowerShell

Command lines are less prone to errors provided the syntax is correct, unlike GUIs that can suffer a glitch every now and then. To create a system image with PowerShell do the following:

1. Open the Windows PowerShell as administrator. To create a System Image in Windows 10 using PowerShell, you will have to run the Wbadmin command.
2. Inside the Powershell window type, then press Enter: wbadmin start backup-backup target: E:-include: C:-quiet-allCritical E: is the target drive where you’re going to save the system image, and C: is the system root drive where Windows is currently installed
3. To extract the created system image, starting over from Windows 10 USB installation media, select advanced startup or open run and type: C: \ Windows \ System32 \ Shutdown.exe / r / o

Use third-party imaging software

If the previous two solutions have not managed to solve the issue there is always an option to use a third-party imaging solution. There are free open source and buying options offering various advantages each. Find out which one works best for you and use it.
