How do I fix error code CAA20003?

NOTE

First, make sure you’re using the latest version of MS Teams. Also, see if you can use the web version and if that’s the case, reinstall or update your app. Checking Microsoft’s server status to outrule outages is also important.

1. Check your date and time settings

1. Press Windows key and click on Settings.
2. Select Time & language on the left pane, then click on the Date & time option on the right.
3. Enable both Set time automatically and Set time zone automatically by clicking on the toggle button.

This should have resolved the error code Caa20003 in Microsoft Teams, and you should now be able to log in. 

2. Remove your email account

1. Press the Windows key and click on Settings.
2. Click Accounts on the left pane, then select the Email and Accounts option on the right.
3. Then click on the Manage button to launch the Outlook Account settings dialog box.
4. Click on the Delete Account from your Device option and select Delete to disconnect your email address.

The same process applies to both Work and School accounts. All you need to do is launch the Settings app on your Windows PC and select Access work or school on the right pane. Then, repeat steps 3 and 4. 

At this point, you can now reconnect your account and check whether you can access Microsoft Teams.

3. Login using Incognito Mode

1. Launch your browser and open a new window in incognito mode.
2. Head to the official Microsoft Teams website and try logging in to your account.

You should also ensure that you’ve disabled all your browser extensions. This is because they might block you from signing in to your Microsoft Teams account.
