How to Fix Microsoft Teams Error CAA20002
To fix Microsoft Teams Error CAA20002, use the following workarounds:
1. Add Your Teams Account to Windows Account Manager
Microsoft Teams accounts are typically assigned by schools or organizations and are different from your personal Microsoft account. If your Microsoft Teams account is different from your Windows account, the Windows account manager is likely causing problems.
To resolve the issue, add your Teams Account to Windows Account Manager using the below instructions:
- Right-click on the Start menu and select Settings from the menu list.
- From the left sidebar, click on the Accounts tab.
- Go to the right side of the page and click the Access work or school option.
- If you don’t see your Teams account, click Connect next to Add a work or school account.
- Now enter your credentials on the Microsoft account page and click the Next button.
- Next, authenticate through the method that is most convenient for you.
If you find that the account is already present, disconnect and reconnect the account using the steps described above. After you add or reconnect the account successfully, log in to the Teams app and see if the problem still persists.
2. Clear Microsoft Teams Cache Files
Piling up cache files could also end up causing the issue. Therefore, if the above method does not resolve the issue, you may want to try clearing the Microsoft Teams cache files.
Before you proceed, make sure that you have completely quit the Teams app and it’s not running in the background.
- Press the Windows+E keys to open the File Explorer window.
- Now navigate to the following path:
%appdata%\Microsoft\Teams
- You can also simply copy and paste the above path into the address bar and press Enter.
