When a Teams Rooms device repeatedly signs out in the Teams admin center, the device loses connection to meeting services and often appears offline or with a red status. The main cause is an expired or invalid device account credential, usually tied to a Microsoft 365 account or an outdated Teams Rooms app version. This article explains why the sign-out happens and gives step-by-step fixes to restore the device to a healthy, online state.
You will learn how to check the device account, update the device firmware, and reauthenticate the device in the admin center. The fixes cover both the Teams admin center and the local device console, so you can resolve the issue even if remote management fails.
Key Takeaways: Restoring a Teams Rooms Device That Keeps Signing Out
- Teams admin center > Teams devices > Teams Rooms: Shows the sign-in status and lets you restart or reauthenticate the device.
- Device account password reset: Fixes expired credentials that cause the device to sign out automatically.
- Local device console > Settings > Account: Displays the exact error message and allows manual sign-in with the device account.
Why Teams Rooms Devices Sign Out in the Admin Center
Teams Rooms devices sign out when the device account cannot authenticate with Microsoft 365. The device account is a normal user account that is licensed for Teams Rooms Pro or Standard. The device uses this account to sign into Teams and to register with the Teams admin center.
The most common root causes are:
- Expired password — The device account password has changed or exceeded its maximum age policy.
- Disabled or blocked account — An admin disabled the device account or a conditional access policy blocks the sign-in.
- Stale device registration — The device is registered under an older Teams app version that no longer supports the current authentication flow.
- Network or DNS failure — The device cannot reach the Microsoft 365 login endpoints, causing the sign-in to fail silently.
When any of these happen, Teams stops the device session and the admin center shows the device as signed out. The device may still show as online if the network connection is alive, but the meeting client cannot start.
How the Sign-Out Impacts the Device
A signed-out device cannot join scheduled meetings, display the room calendar, or use the touch console. The admin center shows the status as “Signed out” under the device name. If the device remains signed out for more than a few hours, the admin center may mark it as inactive.
Steps to Fix a Teams Rooms Device That Signs Out
Follow these steps in order. Each step addresses a specific cause, and you can stop when the device shows as signed in again.
- Check the device status in the Teams admin center
Sign in to the Teams admin center at admin.teams.microsoft.com. Go to Teams devices > Teams Rooms. Find the affected device and note the status column. If it says “Signed out,” proceed to the next step. If it says “Offline,” the device has a network issue, not just a sign-in problem. - Restart the device from the admin center
Select the device, then choose Restart from the top menu. Wait three minutes for the device to reboot. Check the status again. A restart forces the device to reattempt authentication. If the credentials are still valid, the device signs in automatically. - Reset the device account password in Microsoft 365
Open the Microsoft 365 admin center at admin.microsoft.com. Go to Users > Active users and locate the device account, which usually ends with @domain.onmicrosoft.com or a custom domain. Select the user, then choose Reset password. Set a new password and uncheck the option to force a password change on next sign-in. Record the new password. - Update the password on the device console
On the Teams Rooms device, go to the local console. Press the Settings gear icon, then choose Account. Enter the new password for the device account and select Save. The device will attempt to sign in again. If successful, the admin center updates the status within five minutes. - Reauthenticate the device account in the admin center
Back in the Teams admin center, select the device and choose Reauthenticate from the top menu. Confirm the action. This sends a new authentication request to the device. Wait for the device to process it and check the status again. - Update the Teams Rooms app on the device
If the device still signs out, the Teams Rooms app may be outdated. Go to the device console, open Settings, then About to see the app version. Compare it with the latest version listed in the Microsoft 365 message center. If an update is available, install it from the Windows Store or the device manufacturer’s update tool. After the update, restart the device. - Check conditional access policies
If the device account is blocked by a conditional access policy, the sign-in fails even with valid credentials. In the Azure AD admin center, go to Security > Conditional Access. Review policies that apply to all users or to the device account specifically. Ensure the device account is exempt or that the policy allows sign-in from the device’s IP range. After adjusting, test the sign-in again.
If the Device Still Shows Signed Out
Try signing in manually on the device console. Press Ctrl + Alt + Delete on the attached keyboard, then enter the device account credentials. If the manual sign-in fails, the problem is with the account itself, not the device.
Related Failure Patterns and Their Fixes
Teams Rooms Device Shows as Offline in the Admin Center
Offline status means the device cannot reach the Teams service. Check the network cable, Wi-Fi connection, and DNS settings. On the device console, open Settings > Network and verify the IP address and gateway. Run a ping test to login.microsoftonline.com from the device’s command prompt. If the ping fails, fix the network route or proxy settings.
Teams Rooms Device Signs Out After Every Restart
This usually indicates the device account password is set to expire soon. Reset the password as described in step 3, then update it on the device. Also check the password policy in Microsoft 365. Set the device account to Password never expires to prevent future sign-outs. Go to Users > Active users, select the device account, and under Password choose Edit and select the option.
Teams Rooms Device Shows a Sign-In Error on the Console
The console displays an error code like 80070005 or AADSTS50053. These codes point to access denied or a locked account. Unlock the account in the Microsoft 365 admin center by resetting the password. If the error persists, check if multi-factor authentication is enabled for the device account. MFA is not supported for Teams Rooms devices, so disable it for that account or create a conditional access policy that excludes the device account from MFA requirements.
Teams Admin Center vs Local Device Console: Key Differences
| Item | Teams Admin Center | Local Device Console |
|---|---|---|
| Access | Remote via web browser | On the device with keyboard and monitor |
| Main use | Monitor status, restart, reauthenticate | Enter credentials, view error details, update app |
| Error details | Shows status only | Shows full error codes and messages |
| Password update | Not available | Available in Settings > Account |
| Network diagnostics | Limited to status | Full network settings and ping tools |
Use the admin center for quick actions and the local console for deep troubleshooting. If the device is unreachable remotely, you must use the local console to fix it.
Conclusion
You can now fix a Teams Rooms device that signs out in the Teams admin center by resetting the account password, reauthenticating remotely, and updating the device app. Start with a restart, then move to password reset and conditional access checks. For ongoing stability, set the device account password to never expire and keep the Teams Rooms app updated. Use the local console whenever the admin center cannot reach the device.
