Top 7 Ways to Fix Microsoft Teams Sign-in Error

Microsoft Teams is enjoying its dream run in the enterprise market. The software recently surpassed 250 million MAU (monthly active users). With the upcoming native Microsoft Teams integration, the numbers will only increase from here. However, the reliability of the software leaves a big question mark over Microsoft Teams. Sometimes it does not allow users to sign in to the service.

1. Quit Microsoft Teams

Sometimes the sign-in error occurs when you do not exit Microsoft Teams properly and then reopen it from the taskbar or application menu.

Hover your mouse pointer over the lower right corner of the taskbar and you will see the Microsoft Teams icon there. Right click on it and select Exit.

The software will shut down Teams services completely in the background and you can now try to sign in again.

2. Close Microsoft Teams from Task Manager

The problem with the above method is that sometimes users don’t see the Teams icon on the taskbar even though it’s running in the background. In this case, you can use the Task Manager app on Windows and completely close the Teams app and all of its associated background services.

Step 1: Press the Windows key and search for Task Manager.

2nd step: Press Enter and open the Task Manager app.

Step 3: Identify Microsoft Teams in the list. Select the application and click on the End task option at the bottom.

Restart the computer, open Microsoft Teams, and try to sign in again.

3. Check the Microsoft Teams servers

Microsoft Teams is infamous for server outrage. We have seen the company face frequent server-side errors that prevent employees from accessing the software for hours.

You can confirm the issue from the handles on social media or visit Downdetector and search for Microsoft Teams. If you notice strong spikes in outrage for Microsoft Teams, you have no choice but to wait for Microsoft to resolve the issue on their own.

4. Repair Microsoft teams

Microsoft Teams generating connection errors may be due to a system-level bug on your computer. However, Windows does offer an option to repair apps without disturbing them too much. Here is how to use it.

Step 1: Open the Windows 10 Settings app (use Windows + I keys).

2nd step: Go to Apps> Apps & Features and select Microsoft Teams from the menu.

Step 3: Click on the app and go to advanced options.

Step 4: In the next menu, find the Repair option on the Reset menu.

Step 5: Select Repair and let Windows handle the problem in the background.

Open Microsoft Teams and try to sign in again.

5. Clear the Microsoft Teams cache

This could be the main culprit behind the Microsoft Teams sign-in error on Windows 10.

Over time, your computer collects user data in the background to speed up common tasks in the application. Unfortunately, overloading such data can lead to a connection error on your computer. Here’s how to clear the cache and continue using Microsoft Teams as before.

Step 1: Close the Microsoft Teams app and press Windows + R keys to open the Run menu.

2nd step: Type % appdata% MicrosoftTeams in the box and press Enter.

Step 3: The command will open the File Explorer menu with Microsoft Teams files.

Step 4: Select all folders and files and delete them from the computer.

Restart the Windows 10 machine and try to reconnect.

6. Access Microsoft Teams from the web

This is only a temporary solution. If you’re still having trouble signing in with the Microsoft Teams app on Windows 10, you can go for the web version for now.

Microsoft Teams is also available on the web. You can access the service from Google Chrome or Microsoft Edge and clarify the meetings and the schedule for the day.

7. Uninstall Microsoft Teams

The Microsoft Teams web is fine, but it’s not a permanent fix to replace the native app on Windows 10.

You can uninstall the problematic app and download the latest version of the software available from the Microsoft Store.

Go to Windows 10 Settings> Apps> Apps & Features> Microsoft Teams and select the Uninstall button.

Download and install the latest Microsoft Teams app from the web or the Microsoft Store.
