Fix Teams Rooms Device Signs Out after a License Change

Your Teams Rooms device signs out automatically after you change its Microsoft 365 license. This usually happens because the device’s cached authentication token becomes invalid when the license changes. In this article, you will learn why this occurs and how to fix it by re-signing in, clearing cached credentials, and verifying the new license assignment.

Why Teams Rooms Devices Sign Out After a License Change

When you change the Microsoft 365 license assigned to a Teams Rooms device, the device’s cached authentication token becomes invalid. This happens because the token is tied to the previous license’s service plan. The device attempts to refresh the token, but the new license may not include the same Teams service plan. As a result, the device signs out and cannot sign back in automatically.

Another common cause is that the new license does not include the Teams Rooms service plan. For example, if you replace a Teams Rooms Pro license with a standard Microsoft 365 E3 license, the device loses the required service plan. The device cannot authenticate to the Teams service without this plan.

The sign-out is also triggered by the device’s periodic token refresh cycle. The device tries to validate its token every 24 hours. If the token is rejected, the device signs out and shows the sign-in screen.

Steps to Re-Sign In and Restore the Teams Rooms Device

Follow these steps in order to fix the sign-out issue. You need local admin credentials for the device and access to the Microsoft 365 admin center.

1. Verify the new license assignment
   Open the Microsoft 365 admin center at admin.microsoft.com. Go to Billing > Licenses. Confirm that the device’s account has a Teams Rooms Pro or Teams Rooms Basic license. If not, assign a valid license. Wait 30 minutes for the license to sync.
2. Sign in to the device with the local admin account
   On the Teams Rooms device, press Ctrl+Alt+Delete. Use the local admin credentials to sign in. This bypasses the Teams sign-in screen and gives you full desktop access.
3. Clear the cached credentials
   Open File Explorer and navigate to C:\Users\Skype\AppData\Local\Packages\Microsoft.SkypeRoomSystem_8wekyb3d8bbwe\LocalCache. Delete all files and folders in this directory. This removes the invalid cached token.
4. Restart the device
   Click Start > Power > Restart. The device will boot into the Teams Rooms app. If it does not, press Ctrl+Alt+Delete and select Sign out, then sign in again with the local admin account.
5. Sign in with the device account
   On the Teams Rooms sign-in screen, enter the device account credentials. Use the account that has the new license assigned. The device should now authenticate and stay signed in.
6. Verify the device in Teams admin center
   Go to the Teams admin center at admin.teams.microsoft.com. Select Devices > Teams Rooms. Find your device and check that its status is Healthy. If it shows as Offline, wait 10 minutes and refresh the page.

If the Device Still Signs Out

If the device signs out again after following the steps, you need to re-provision the device. In the Teams admin center, go to Devices > Teams Rooms. Select the device and choose Restart. If that does not work, select Delete to remove the device from the admin center, then let the device re-register automatically on the next boot.

If the Device Still Has Issues

Teams Rooms Device Shows a Blank Screen After Sign-In

A blank screen usually means the device account is not licensed correctly. Check that the license includes the Teams Rooms service plan. Go to Microsoft 365 admin center > Billing > Licenses and view the assigned license. Look for the service plan named Microsoft Teams Rooms. If it is missing, assign a different license that includes it.

Teams Rooms Device Cannot Sign In with the Device Account

This error appears when the device account password has changed or the account is disabled. Reset the password in the Microsoft 365 admin center. Then sign in on the device with the new password. If you use a resource account, ensure the account is not blocked from sign-in.

Teams Rooms Device Signs Out Every Day

Daily sign-outs indicate that the token refresh is failing. This can happen if the device’s time is out of sync. Check the device’s date and time settings. Enable automatic time synchronization. Also verify that the device can reach the Microsoft online services. Open a web browser on the device and go to login.microsoftonline.com to confirm network connectivity.

Teams Rooms Pro vs Teams Rooms Basic: Key Differences for This Fix

Item	Teams Rooms Pro	Teams Rooms Basic
License cost	Paid per device per month	Free but limited to 25 meeting rooms
Service plan name	Microsoft Teams Rooms Pro	Microsoft Teams Rooms Basic
Required for sign-in	Yes, without it the device signs out	Yes, without it the device signs out
Admin center features	Full remote management and monitoring	Basic device status only
Best for	Large conference rooms and critical meeting spaces	Small huddle rooms with limited needs

Both licenses include the Teams Rooms service plan, which is the key requirement for the device to authenticate. If you change from Pro to Basic, the device will still work, but you lose advanced management features. If you change to a license without the Teams Rooms service plan, the device will not work at all.

You can now fix the sign-out issue by clearing the cached token and re-signing in with a valid license. Always verify the license includes the Teams Rooms service plan before signing in. If the problem recurs, check the device’s time settings and network connectivity. For persistent issues, re-provision the device from the Teams admin center. Use the Teams Rooms Pro license for full remote management capabilities.
