MC1290834 - Teams Rooms sign-in failures after password reset from Pro Management Portal

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
• Inform your helpdesk or support teams of this issue to reduce troubleshooting time
