Login Failed When Integrating M-Files with Microsoft Teams

Hey everyone,

I'm facing a "Login failed" error while integrating M-Files with Microsoft Teams when entering the vault URL.

What I've Checked So Far:

  •  M-Files Web is accessible outside of Teams.
  • Using the correct vault URL format (copied directly from M-Files Web).
  •  Default port 443 is being used.

Has Anyone Encountered This Issue?

If you've successfully set this up, could you share any additional troubleshooting steps?

I've attached a screenshot of the pop-up issue that appears in Teams during integration.
