How to Fix Microsoft Teams Keep Restarting

Having problems with trying to fix Microsoft Teams restarting?

Microsoft Teams is a great app to use for productivity purposes, like office calls and group chats for companies. The application allows users to video call, send audio files, access other third-party applications, and more!

However, a common bug is that Microsoft Teams keeps restarting, among others. This issue is extremely annoying since the restart can happen arbitrarily and cut users off from calls and conversations. In this article, we will be tackling solutions and possible fixes to help rid yourself of this cumbersome problem.

Listed below are methods and solutions that we’ve collected all over the internet. For us at Saint, making sure our readers are given quick and reliable solutions is a company priority. Here’s what you can do to fix Microsoft Teams randomly restarting.

Let’s get started!


1. Terminate the Microsoft Teams Application.

Although Microsoft Teams keeps restarting on your device, this doesn’t mean that the program fully closes. It’s a common bug for programs to leave behind background processes even though they’ve been fully closed already. For cases like this, the problematic bug can constantly remain running in the background.

This causes Microsoft Teams to continue restarting and running into errors despite rebooting. Luckily, Windows comes with a feature called the ‘Task Manager’. The Task Manager monitors all running programs, in the foreground and background. We’ll be using this to completely terminate Microsoft Teams from memory so you can boot it back again properly.

Here’s how you can terminate Microsoft Teams with Task Manager:

  1. First, open up the Task Manager by using the hotkeys CTRL + SHIFT + ESC. If that’s out of your reach, you can always open the Start menu and search for ‘Task Manager‘.
  2. Now, if your Task Manager doesn’t have any tabs, click on the More details button at the bottom-left corner to expand the manager.

  1. Then, navigate to Processes and click on any random app that’s running. Type in ‘Microsoft Teams‘ and that should locate and highlight Microsoft Teams for you.
  2. Finally, right-click the process and select End Task to terminate the program.

When you’re done with that, run Microsoft Teams again to let it boot from scratch. Go ahead and test the program by running it for a couple of minutes.


2. Restart Your Computer.

If terminating Microsoft Teams doesn’t work, you may have to completely restart your computer. Restarting your PC or laptop will terminate all software bugs or glitches that could be causing Teams to malfunction.

Furthermore, this will close all programs, including the operating system, so you can best be sure that anything that’s messing with your Microsoft Teams will be freed from memory.

Here’s how you can restart your computer:

  1. On the bottom-left corner of your screen, click on the Windows icon to open the Start menu.
  2. Now, click on the power icon just above the Windows icon. Select Restart to begin shutting down your computer.

Your PC will automatically turn back on, so just leave it alone until that process finishes. Once that’s done, open up Microsoft Teams and test it out for a couple of minutes. Hopefully, the problem is resolved.


3. Delete Microsoft Teams Cache Files.

Cache files are often one of the most underrated assets that a program can have. These files save all your settings and preferences, making every visit to the same program as similar to how you left it.

This way, even if the program is closed or your computer has shut down, you’ll retain the same settings and preferences when reopening the program. However, these files can be problematic if they are corrupted or has faulty data.

To resolve this, we’ll have to delete the problematic cache files. Your personal settings configuration will be lost, and you’ll have to reconfigure your preferences again. But don’t worry, you will not lose any of your personal records.

Here’s how you can delete Microsoft Teams cache files:

  1. Go ahead and open up the Run dialog box by pressing the hotkey Windows key + R.

  1. Once that opens, type in ‘%appdata%’. You should be directed to a list of folders.
  2. Now, look for Microsoft and open the folder.
  3. Lastly, once you’re there go ahead and delete the Teams folder.

Voila! Your Microsoft Teams cache files have now been deleted. Feel free to open Microsoft Teams and test it out for a couple of minutes to see if the issue has been resolved.


4. Update Your Version of Office 365.

What’s often forgotten and undervalued by a lot of Windows users is updating their Microsoft Essentials. Office 365 handles everything from MS Word, PowerPoint, Excel, and so on. Although these applications have worked magnificently for years, the occasional update still happens.

An outdated version of Office 365 might not be the first suspect to Microsoft Teams constantly restarting. However, it does affect the overall performance of the program, since Teams also relies on Office 365’s applications like MS Word.

Here’s how you can update Office 365:

  1. Let’s begin by pressing on the Windows key to bring up the Start menu.
  2. Now, simply type in ‘Microsoft Word’ and click on the first app that’s returned from your query.
  3. When MS Word opens, go ahead and create a dummy file. After that, go to the File menu at the top-left corner of your screen.
  4. From there, go to the Account or Office Account tab.

  1. Finally, under Product Information, simply click on Update Options and select Update Now from the drop-down menu.

Any updates for Office 365 will now be installed and downloaded on your computer. Although this doesn’t need to be a regular occurrence, updating your default applications like this is a great way to discover new features. Now go ahead and open up Microsoft Teams for a few minutes to see if the issue has been resolved.


5. Uninstall and Reinstall Microsoft Teams.

With all the above methods exhausted, you may have to reinstall Teams to try and fix your issue. If the constant restarting is due to an underlying problem with Microsoft Teams’ faulty code or corrupted files, uninstalling it will clear all the bad files from your hard drive.

When you reinstall the program, you should then be running an authentic and fully-functional version. This way, any problems that you were facing should be completely erased.

Here’s how you can uninstall Microsoft Teams:

  1. First, open up the Start menu by pressing on the Windows key.
  2. Now, search for ‘Add or remove programs’ and open up the first query that’s returned from your search.
  3. Next, underneath Apps & Features, utilize the search bar and look for ‘Microsoft Teams’.

  1. Finally, find and click on the application and select Uninstall.

Just follow the prompts until the program is completely erased from your computer. This should also delete all your cache files, but feel free to repeat Step 3 to clear your local cache files.

Now, here’s how you can reinstall Microsoft Teams:

  1. Simply go to their website and click Download for desktop.
  2. Your download should begin, once it’s finished just tap and run the installer. Follow the prompts intuitively, and Microsoft Teams should be fully installed.
