When the user or other programmes change the settings of the Microsoft Teams app without the user’s knowledge, errors like these can happen when the app is being used on the system. Because of this, we recommend that users fix or reset the app through the settings app. Let’s look at a few steps that show how to do this on a Windows system.

Check if the Microsoft Teams Server is down
When a user is using any application on the system and gets a log-in or sign-in error, there may be a problem with the Microsoft Teams server. Either the server isn’t working or maintenance is being done. So, if a user wants to see if their server is down, they can go to the website.
If the server is down or being worked on, we ask users to give it some time and try again to see if it is back up. Once the server is up, try to see if you can easily sign in to the Microsoft Teams app.
Check your Internet Connection
When this happens, one of the main things to do is check the internet connection and make sure the system has a stable and fast internet connection. We suggest that our users follow the steps below to check their internet connection.
- If you use a Wi-Fi adapter to connect to the internet, restart your router once.
- If you are using an Ethernet connection, unplug the Ethernet cable from the system and plug it back in.
- Now, check to see if the connection to the internet is stable or not. If it is still not stable, contact your Internet service provider to get a better connection.
