Check Your Network Connection
Make sure your connection is stable. Restart your router to fix any potential bandwidth and speed issues and check if you can log in to Teams. Restart your computer as well, if you haven’t done that already.
Additionally, use a cable connection if that’s possible, or switch to a different network. For example, you can use your smartphone as a mobile hotspot. Speaking of which, do check if there are other devices connected to the same network and temporarily disconnect them.
Check Your Firewall Configuration
If your computer is managed by an organization, contact your IT admin and ask them to check if the current firewall configuration has anything to do with the login error you’re experiencing.
On the other hand, if you’re using your personal computer, disable your firewall and antivirus and check if the error code 0xcaa82ee7 persists. If you can log in to your account without any problems, whitelist Teams in your antivirus and firewall settings. Go to your firewall’s support page for more information. If you use the Windows Defender firewall, follow the instructions available in this guide.
