Most Common Microsoft Outlook errors

When you have a program, you know before you even start to use it or even know how that you are going to have problems with it. There are always going to be error messages and things that don’t work on any program you buy or download; guaranteed. Even some of the most famous program developers in the world make mistakes from time to time and it is a small price to pay for the programs you get and that is a fact. Microsoft Outlook is like any other program; it has its errors. Here are some of the most common errors for Microsoft Outlook on your computer.

1. Problem receiving emails

Sometimes you can be waiting on really important emails. It is really infuriating when you know that they have been sent, however every time you check your email box, there is nothing there! Your inbox is empty and your patience is wearing thin, so could it possibly be an error with Microsoft Outlook? There is a high probability that this is the problem. The program can be a bit slow on receiving emails sometimes, often even by days. This can be caused by any number of things, from having too many emails coming through or having too many emails in your inbox. If you click ‘send and receive’ at the top, it should speed up your emails coming through, however, so give that a try if you’re waiting on anything to come through. If this doesn’t work, however, your inbox may be full. Try permanently deleting some useless messages and then click ‘send and receive’ again. All your emails should come through then!

2. General slow performance

Outlook, while it has its advantages, can often be very slow. It is probably slower than some other email programs that require a browser but it is quicker to access, which may make up for this fact. However, sometimes sluggish performance can be really irritating, so it may be wise to try and fix it if you can. One of the reasons it may be acting slow is if you have too many other Windows applications open. Applications that may interfere with your Outlook’s speed could be anything from Microsoft Word to Windows Live Messenger. If any of these are open, try closing them and see if that helps with the speed problem.

3. Corrupt files

.dbx files are not accessible by Microsoft Outlook. Therefore, they can cause problems with your emails if you have them within them. To solve this problem, you may have to delete all of your attached email accounts and then reattach them before you can open your emails again. These corrupt files can also cause you to be unable to delete emails. You will need to transfer these deleted corrupt files into a separate deletion folder as this is usually caused by the folder being corrupt. Of all the other most frequent problems with Microsoft Outlook, however, this is probably the least likely to happen, which shows how few problems there actually are with this application after all that!

Conclusion

So there are the most common problems with Microsoft Outlook! Not much wrong at all, is there?

If you encounter an error saying, “Invalid file handle” when you try to rename, copy, delete a file or other operations in your Windows 10 computer, then read on as this post will guide you in what you can do to fix it. This kind of error pops up when the operating system tries to carry out an operation on a folder or file using the following words:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9

When you rename or create a folder or file using the reserved words given above, you could encounter an error that says, “The specified device name is invalid”. This occurs since these words are Windows system reserved words that you can’t use, unlike any other words. Thus, if you have a folder or file which contains any of the reserved words on another computer that runs a non-Windows operating system and you try to copy or rename it Windows, then it’s no wonder why you’re getting this error message. In such cases, you can always click on the Skip button to stop the operation. However, if there are various folders or files, you can just use the Command Prompt to carry out the task. All it takes is a simple command that will get rid of the folder as well as the files in it. How? Refer to the instructions given below. Step 1: Tap the Win + R keys to open the Run utility. Step 2: Next, type “cmd” in the field and then tap Enter to open Command Prompt. Step 3: After opening Command Prompt, execute the following command:

rd \.file-folder-path /S /Q

Note: The “rd” command will remove the directory or the folder while the “\.” command will select the current computer. The “/S” command, on the other hand, helps you in removing all the sub-directories and the files that are in the CON folder. The “/Q” command is not really mandatory since it helps you remove everything silently without any confirmation message. For example, if you have a folder named “CON” located on your Desktop, the path will be like this “C:/Users/<username>/Desktop/CON”. In this case, the command should be like this:

rd \.C:Users<username>DesktopCON /S /Q

However, if the error pops up for a whole different reason, you could use the following command instead to remove the reparse point extended functionality. Once you’ve entered the given command below, you should now be able to delete the file.

FSUTIL reparsepoint delete C:Users<username>DesktopFileName DEL C:Users<username>DesktopFileName

The quickest way to control and manage the volume of your Windows 10 PC is using the Volume control icon in the system tray. However, you might encounter issues in using it especially if you recently updated your PC. After the update, if it no longer responds to mouse clicks, be it a right-click or left-click, read on as this post will show you what you can do to remedy that issue. If you think that you’re the only one who has experienced this problem, you are mistaken as several users also reported that the volume icon does highlight and shows the volume level if you hover the cursor over it but it does not really do anything at all. This is definitely the quickest way to change the audio output in Windows 10 especially when you have to change from speakers to your earphone and whatnot. If you are one of the users whose Windows 10 Taskbar Volume Control icon has stopped working and every time you click on the icon and nothing happens and you’re still not able to adjust the volume of your Windows 10 computer, read on as this post will show you what you can do to fix that problem. Although the audio is working just fine, you will still not be able to adjust the volume from its control icon. The problem is most likely related to the UI interaction. There are times when icons in the taskbar also experience the same issue where you can hover your mouse over them but nothing happens when you click on them. As mentioned, the issue with the volume icon does not seem to affect the actual audio of the computer. Double-check to confirm and if it turns out that the audio is indeed working fine, you can use the hardware of your keyboard to manage and control the volume, however, the software just won’t work. This issue is really inconvenient especially for users who connect their laptops to a bigger display. To fix this issue, here are some suggestions you need to check out.

Option 1 – Try to restart the Windows Explorer

This option may sound silly but it has actually worked in fixing the issue for some users. So if anything gets stuck on the taskbar or system tray, the best way to revive them is by restarting Windows Explorer.

• Right-click on the taskbar and then select the Task Manager.
• Next, look for Windows Explorer under the Processes tab.
• Then right-click and select restart.
• After that, wait for the restart process to be completed and for the user interface to refresh. Note that you will notice the Taskbar disappearing and reappearing again. It will reload the entire user interface and allows you to access the volume icon. It should work this time.

Option 2 – Restart the Audio services

Restarting the audio services in your computer can also help you fix the volume control issue and to do that, refer to these steps:

• Tap the Win + R keys to open the Run dialog box.
• Type in “services.msc” in the field and hit Enter to open Services.
• From there, look for Windows Audio and then right-click on it and go to Properties.
• After that, you have to make sure that the Startup Type is set to Automatic.
• Then click on the Stop button. Once it has stopped, start it again.
• Now restart your computer and see if you can now access the volume icon on the taskbar.

Option 3 – Try to update or roll back the Audio driver

If the glitch in your audio 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 devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
• 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 4 – Try running 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 volume control issue on your PC. 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.

Windows 10 has a lot of several useful features and one of them is the Nearby Sharing feature. You can access this feature by going to Start > Settings > System > Shared experiences. From there, switch on the Nearby Sharing option and select the folder where you want to download the files to. This feature is really useful as it allows you to share files. However, there were reports from a number of users recently stating that Nearby Sharing is not working on their Windows 10 computers. If you are one of the users facing this problem, you might want to try checking if the Windows 10 v1803 Update is installed on your computer or not. You could also try to check if Bluetooth supports low energy mode or you could also try bringing the device closer or check if the adapter has Bluetooth version 4.0 or later. For more information, refer to each one of the given options below.

Option 1 – Try checking if Windows 10 v1803 Update is installed

To check if the Windows 10 v1803 Update is installed on your computer, go to Start > Settings > System > About. From there, scroll down to the Windows specifications and check the Version. If it is 1803 or above, then the Nearby Sharing feature should be active on your computer. However, if you find that Windows 10 v1803 Update is not installed yet, then you need to update your computer to its latest version and then see if it fixes the problem or not.

Option 2 – Verify if Bluetooth supports low energy mode

Although low energy mode is not really necessary in using Nearby Sharing, there are some Bluetooth terminals that support low energy mode which makes a lot of difference. Thus, you need to check if Bluetooth in your computer supports low energy mode by following these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After that, expand the list of Bluetooth adapters, and then right-click on your adapter and select Properties.
• Go to the Details tab and select Bluetooth radio supports Low Energy Central Role from the drop-down menu and if its value says “<true>”, it means that your Bluetooth supports low energy mode, otherwise, it doesn’t.
• If your Bluetooth does not support low energy mode, then you might want to consider purchasing an external one.

Option 3 – Try bringing the devices closer

Nearby Sharing might not work if your devices are not close enough. Thus, you need to bring your devices closer together and see if it fixes the problem. And when you do, make sure that Network Sharing is switched on for all the concerned devices.

Option 4 – Make sure that you’re using Bluetooth version 4.0 or later

For you to use the Nearby Sharing feature, you have to make sure that the adapter for all the concerned devices is using Bluetooth version 4.0 or later. So if one of the devices or if all the devices are not using this version or later versions, then you must buy an external Bluetooth adapter for you to enjoy the Nearby Sharing feature.

External hard drives have become essentials as they store data. However, they are also prone to issues and one of them is the “The device is not ready”. You could encounter this error when you try to access your connected hard drive. This error won’t allow you to access the contents of your hard drive so unless you fix it, you won’t be able to access any of the files on your hard drive. One of the most likely causes of this error is a hardware defect. Aside from that, it could also be due to loose connections, obsolete device drivers, as well as compatibility issues between the operating system and the hard drive. Before you start troubleshooting the problem, you need to determine if you were able to access your hard drive before you encountered the error or not. If not, you need to check the compatibility of the device with your operating system as it could be the reason why you’re getting the error. There are several potential fixes you can check out to fix this error. You can try to check the hardware connections, run the built-in Hardware and Devices troubleshooter, as well as the USB troubleshooter. You could also run the CHKDSK utility or update the drivers of the device or the USB drivers.

Option 1 – Try checking the hardware connections

The first thing you have to do before you further troubleshoot the problem is to check the hardware connections of your computer and see if there are damaged ones, just like with USB ports, it would also affect the overall connectivity of the device with the computer. So if you notice some irregularities in the connecting cable physically, you might have to buy another one and replace it and then see if it fixes the problem or not.

Option 2 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect the external devices and check if the error is now gone.

Raptor Lake, a new and upcoming Intel 13th generation CPU will break the 6GHz barrier for the first time ever in normal working mode, overclocked mode in Intel words will go as high as 8GHz. CPU will be 15% faster than Alder lake in single-threaded tasks and a stunning 41% faster in multi-threaded workloads.

The current world record for overclocking is 8.72GHz done with AMD FX-8370 and Intel is aiming at breaking that record with Raptor Lake, of course, this kind of extreme overclocking will require some top-of-the-line nitrogen cooling systems.

Raptor Lake will run on the current LGA 1700 socket, so you will not need to buy another motherboard for CPU and they will also be manufactured on a 10nm process which means that you will need to take care of cooling and power supply if they really go over 6GHz.

Mid-range Intel Core i5-13600K processor will come with 14 cores inside and 20 threads running at a maximum P-core frequency of 5.1GHz, while Core i7-13700K will have 16 cores and 24 threads and run on 5.3GHz max P-core frequency. Best i9-13900K will come packed with 24 cores, 8 of them will be P-cores, and the rest 16 are E-cores, and 32 threads. It will reach 5.4GHz frequency but it was stated it can go to 5.8GHz with Thermal Velocity Boost.

After this statement, we can clearly see that the 6GHz breaker CPU will probably be an i9 special KS variant. In other words, specially tested and picked existing i9 running at higher speeds as was with Alder Lake as well where normal i9-12900K ran at 5.2GHz while i9-12900KS was running at 5.5GHz.

System Interrupts are operating system processes that function as an alert system for the CPU. So whenever a scenario needs the attention of the CPU, it alerts the CPU about it. In turn, the CPU suspends what it is doing, saves it, and then takes care of that important job and once that job is completed, it resumes back to what it was doing. This indicates that although System Interrupts appears as a process, it’s actually not. As a matter of fact, it is like a manager that reports to the CPU about all interrupts that happen on a hardware level, e.g. hardware interrupts. And if there are lots of interrupts, this means that there might be various errors occurring on a hardware level. As a result, it may take a lot of system resources. And if you consider disabling System Interrupts, stop right there as your computer will almost become useless without it. So if you see System Interrupts consuming high CPU usage in your Windows 10 computer, you can fix it without having to disable it and cause more problems. If System Interrupts takes up more than 5 to 10% of CPU, then you definitely have a problem. This could be happening due to some hardware or driver issue. The first thing you can do is to try rebooting your computer once and see if the issue comes back or not. High CPU usage of System Interrupts is a huge backlog for the CPU and it stays in the loop. If a simple system restart didn’t fix this issue, here are some suggestions you can try.

Option 1 – Try to update the hardware drivers

As stated, the problem might have something to do with hardware drivers so you can try to update these drivers and see if it works.

• Reboot your computer into Safe Mode with networking support.
• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, update all the outdated Hardware drivers on your computer.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Note: On the other hand, if a recent update has caused the System Interrupts high CPU usage, then you might want to roll back your hardware drivers to their previous versions. You can check with the Windows Update History to check out any recent updates as well as the previous ones.

Option 2 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

Option 3 – Try to enable or disable Hardware

If you do not want to remove hardware, you can just disable them using the Device Manager. Note that this can also be applied to the internal hardware.

• Tap the Win + X + M keys to open the Device Manager.
• Next, navigate to the device you want to disable.
• Then right-click on it and choose to disable the device.

Note: Make sure that you disable one device at a time and then give it a couple of minutes and check if there are any changes in the CPU usage to pinpoint the hardware. And if there is no change, you need to enable the device you’ve just disabled and then proceed to disable the next hardware device. If there are changes, then it’s probably the culprit. Just keep in mind that you must no disable any device that is needed to keep your system up and running.

Option 4 – Try to update the BIOS/UEFI

Updating the BIOS/UEFI can help you fix the high CPU usage of System Interrupts but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Restart your computer to apply the changes made.

Option 5 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
