1. Clear the Teams Cache
Cache files stored by Microsoft Teams can sometimes become damaged or outdated, causing bugs and glitches that can trigger the error. By clearing the Teams cache, you remove these problematic files and force the app to create new, fresh ones.
- Once you’ve done this, open Teams and see if the error is gone.
2. Enable TLS 1.2
TLS 1.2 is an updated, secure way to connect to Microsoft services. If it’s not enabled on your computer, Teams may not be able to communicate with Microsoft’s servers, which can cause the error.
3. Update Microsoft Teams
Updates for Microsoft Teams often include bug fixes that improve how it connects with Microsoft’s servers and handles network connections. Keeping Teams up to date helps prevent and fix these errors.
4. Reinstall the Application
Reinstalling Teams can solve problems caused by corrupt installation files or leftover settings that may lead to the CAA20002 error.
