MC1290834: Teams Rooms sign-in failures after password reset from Pro Management Portal
Password resets via Teams Pro Management Portal may cause Teams Rooms devices to fail sign-in due to a forced password change prompt they cannot complete, leaving devices in a CannotSignIn state. Avoid resetting these passwords in PMP and manually remediate affected devices if needed.
[Introduction]
We're investigating an issue where password resets performed in the Teams Pro Management Portal (PMP) may cause Teams Rooms devices to fail sign-in. A recent change in password reset behavior is the likely root cause and may prevent Teams Rooms devices from completing sign-in.
[How this affects your organization:]
Who is affected:
- Organizations using Teams Pro Management Portal (PMP) to manage Teams Rooms resource accounts
What will happen:
- Password resets initiated in PMP may trigger a change password at next sign-in requirement on the account.
- Teams Rooms devices cannot complete interactive password change prompts.
- Affected devices enter a CannotSignIn state.
- Devices may remain signed out without automatic recovery until manually remediated.
- This issue primarily affects Teams Rooms resource accounts.
[What you can do to prepare:]
- Avoid resetting Teams Rooms resource account passwords through the Pro Management Portal.
- If a password reset is required:
- Verify device sign-in immediately after the reset
- Manually remediate any devices that remain in a signed-out state
