How to Fix Microsoft Teams Error Code CAA301F7

June 9, 2021 by Madalina Dinita Leave a Comment

The Redmond giant launched Microsoft Teams in 2017. Four years later, the app is still affected by a long list of bugs and errors. Things are not perfect and there’s still plenty of room for improvement. Login errors remain one of the most frequent issues affecting Teams users. In this guide, we’re going to focus on the annoying error code CAA301F7 and how you can fix it on Windows 10.

How Do I Fix Teams Error Code CAA301F7?

Use the Web App

The web app is rarely affected by the same issues that are plaguing the desktop app. So, go to teams.microsoft.com, and check if you can log in to your account. In this manner, you can quickly access your Teams account and take care of any urgent tasks. After that, you can resume the troubleshooting process with the help of the solutions listed below.

Check Your Network Connection

Make sure your Internet connection is stable. Restart your router and switch to a cable connection. Don’t forget to disconnect the other devices using the connection to free up more bandwidth for Teams. If you’re using a wireless connection, move your laptop closer to your router and check if the issue is gone.

Disable Your Antivirus and Firewall

First of all, check if your antivirus and firewall are indeed to blame for error code CAA301F7. Temporarily disable your antivirus and firewall and check the results.

If the error is gone, whitelist Teams in your antivirus settings. Additionally, add a new firewall rule for Teams instructing your security tool to let Teams run on your machine. For detailed instructions on how to do that, go to the support page dedicated to your antivirus and firewall.

Clear Teams Login Information

You can quickly fix Microsoft Teams login issues by clearing the login data from the Credential Manager.

  1. Type “credential manager” in the Windows Search field, and double-click on the first result.
  2. Then, select Windows Credentials and locate your Teams login data.ms-teams-credential-manager
  3. Select all the entries and hit the Remove option.
  4. Restart your computer, launch Teams again, and check the results.

Clear the App Cache

Your app cache might be interfering with your current Teams session preventing you from logging in.

  1. Right-click on the Teams taskbar icon and select Quit to exit the app.
  2. Then type %appdata%\Microsoft\Teams in the Windows search field and hit Enter.
  3. Delete all the files and folders from the Teams folder.ms teams cache folders windows 10
  4. Launch Teams again and check if you can log in to your account now.

If the issue persists, navigate to C:\ProgramData\Intel\ShaderCache\Teams_1 and delete the Teams_1 cache file as well.

Launch Teams With Admin Rights

Run Teams with admin privileges and enable Windows 8 or Windows 7 compatibility mode. Many users confirmed this combo fixed their Teams login issues.

  1. So, right-click on your Teams desktop icon and select Properties.
  2. Then, click on the Compatibility tab.
  3. Under Compatibility Mode, check the option that says Run this program in compatibility mode for and select Windows 8 or Windows 7.

Enable WS-Trust 1.3
