How to Solve Microsoft Teams Error Code CAA301F7

To fix Microsoft Teams Error Code CAA301F7, you can try the following solutions –

1. Check the Internet Connectivity

The limited flow of the Internet connection might cause this login error. Therefore, we recommend you check your Internet connectivity and make sure it is stable. If the network connectivity is not so good, you can disconnect other devices and if needed, take your device near the router and check if it fixed this error. In case your network connectivity is good, you can try the next solution.

As it turns out, this problem generally appears while trying to log in to the account, so the next thing we need to delete the default Windows Credentials file and see if it works.
To delete the Teams credentials, do the following –

  • Open the Start menu, search for Credential Manager, and then open it.
  • Under Manage your credentials, select the Windows Credentials option.
  • Now expand Microsoft Team and select Remove to delete the credentials.
  • Restart your computer, launch Microsoft Teams and try login again to check the results.

3. Delete your Microsoft Teams cache

If deleting the login credentials doesn’t help you fix the error, then clear your cache and see if it works. To do this, try the following –

  • Press the Win + R keys to open the Run dialog box.
  • In the text field, enter the following path and press Enter –
C:UsersuserAppDataRoamingMicrosoftTeams
  • On the following page, select the files available there and then delete them.
  • Then restart your Microsoft Teams app and see if the problem is resolved now.

4. Turn off Windows Defender Firewall

If none of the above solutions you find helpful and the problem is persisting, it seems the Microsoft Teams app is blocked and it’s now unable to access the internet connectivity. In this case, we recommend you to turn off your Windows Defender Firewall and it should fix the Error Code CAA301F7.
To turn off your Microsoft Defender Firewall, try the following steps –

  • First of all, open the Control Panel window.
  • Select the Windows Defender Firewall option from the item list.
  • From the left pane, select the Turn Windows Defender Firewall on or off option.
  • Under the Private network settings section, check the box next to the Turns off Windows Defender Firewall (not recommended).
  • Similarly, turn off the Windows Defender Firewall under the Public network settings section.

Once you perform the above actions, check if you’re now able to log in to your account. Also, don’t forget to turn on the Windows Defender Firewall no matter whether the error code CAA301F7 is fixed or not. Because in this state, your computer will be more prone to viruses that can disrupt your system.
