Fix Teams Rooms resource account sign-in issues

Microsoft Teams Rooms signs in to Microsoft Exchange Server or Microsoft Exchange Online and Microsoft Teams or Skype for Business to fetch calendar information and join meetings. These interactions are monitored by using different signals in the Microsoft Teams Rooms Pro Management portal, such as Sign in (Exchange) and Sign in (Teams). This article helps you troubleshoot common sign-in issues and issues that are related to specific signals.

Symptoms

In the Teams Rooms Pro Management portal, one or more signals that are related to the sign-in process are shown as Unhealthy. Users also experience one or more of the following issues on the Teams Rooms device:

• The room console shows a banner at the top that indicates that the sign-in fails.
• Scheduled meetings aren't listed on the room console. This usually indicates an Exchange sign-in failure.
• The room's display name is missing.
• Although scheduled meetings are listed on the room console, the Join button is unavailable and you can't start an unscheduled meeting. This usually indicates a Teams or Skype for Business sign-in failure.

Additionally, Event ID 2001 is logged under Applications and Services Logs > Skype Room System in Event Viewer. For example, the following event is logged:

{"Description":"Network status : Healthy. Exchange status : 80131500 : AADSTS50076. Signin status: NotApplicable. Teams Signin status: Unhealthy.","ResourceState":"Unhealthy","OperationName":"Heartbeat","OperationResult":"Fail","OS":"Windows 10","OSVersion":"10.0.19044.1889","Alias":"","DisplayName":"","AppVersion":"4.13.132.0","IPv4Address":"192.168.0.53","IPv6Address":""}

Resolution

Sign-in issues can occur for different reasons. The following options can help you fix common issues that cause a sign-in failure.

Check whether multi-factor authentication (MFA) is enabled

Teams Rooms resource accounts shouldn't be configured to use MFA. To check whether MFA is enabled, use one of the following options:

• Review the device log file.

  1. On the Teams Rooms device, open Event Viewer, and then go to Applications and Services Log > Microsoft > Windows > Microsoft Entra ID > Operational. Or, download the device's diagnostic log files, extract the downloaded .zip file to a folder, then open the Windows\EventLog\Microsoft-Windows-AAD_Operational.evtx file.
  2. Look for Event ID 1098. If you see error code AADSTS50076 or AADSTS50079, it means that MFA is enabled on the resource account.

• In sign-in logs on the Azure portal, if you see a Failure status with error code 50079 or 50076, and the error description says "Due to a configuration change made by your administrator, or because you moved to a new location, you must enroll in multi-factor authentication to access.", it means that MFA is enabled on the resource account.

To fix this issue, contact your identity management team or see Set up multi-factor authentication for Microsoft 365 for more information.

Check Conditional Access policies

To check whether sign-in is blocked by Conditional Access policies, use one of the following options:

• Review the device log file.

  1. On the Teams Rooms device, in Event Viewer, go to Applications and Services Log > Microsoft > Windows > Microsoft Entra ID > Operational. Or, download the device's diagnostic log files, extract the downloaded .zip file to a folder, then open the Windows\EventLog\Microsoft-Windows-AAD_Operational.evtx file.
  2. Look for Event ID 1098. If you see error AADSTS53003, it means that sign-in is blocked by Conditional Access policies.

• In sign-in logs on the Azure portal, if you see an Interrupted status with error code 53003, and the error description says, "Access has been blocked by Conditional Access policies. The access policy does not allow token issuance.", this means that the sign-in is blocked by Conditional Access policies.

For more information about supported Conditional Access assignments for Teams Rooms resource accounts, see Conditional Access and Intune compliance for Microsoft Teams Rooms. To fix the issue, contact your identity management team or see Configure Microsoft Entra Conditional Access for more information.

Check whether the resource account's password has expired

If a Teams Rooms resource account's password is set to expire after some time, it may cause sign-in failures.

To check whether the password of the resource account is expired, use one of the following options:

• Review the device log file.

  1. On the Teams Rooms device, open Event Viewer, and then go to Applications and Services Log > Microsoft > Windows > Microsoft Entra ID > Operational. Or, download the device's diagnostic log files, extract the downloaded .zip file to a folder, and then open the Windows\EventLog\Microsoft-Windows-AAD_Operational.evtx file.
  2. Look for Event ID 1098. If you see error code AADSTS50055, this means that the password is expired.

• In sign-in logs on the Azure portal, if you see an Interrupted status, and the additional details contain the following message, it means the password has expired.

  The user's password is expired, and therefore their login or session was ended. They will be offered the opportunity to reset it, or may ask an admin to reset it via https://docs.microsoft.com/azure/active-directory/fundamentals/active-directory-users-reset-password-azure-portal.

To fix this issue, reset the password by using one of the following methods, then update the password in Settings on the device.

• Sign in to the account in a web browser, and then reset the password.
• Ask an administrator to reset the password.

To avoid having to reset the resource account password and then sign in to each Teams Rooms device again, you can turn off password expiration for the account.

Verify that you use the correct credentials

An incorrect username or password can also cause sign-in failures.

To check whether an incorrect username or password is used, use one the following options:

• Review the device log file.

  1. On the Teams Rooms device, open Event Viewer, and then go to Applications and Services Log > Microsoft > Windows > Microsoft Entra ID > Operational. Or, download the device's diagnostic log files, extract the downloaded .zip file to a folder, and then open the Windows\EventLog\Microsoft-Windows-AAD_Operational.evtx file.
  2. Look for Event ID 1098. If you see error code AADSTS50126, this means that the username or password is incorrect.

• In sign-in logs on the Azure portal, if you see a Failure status that shows code 50126, and the error description says "Error validating credentials due to invalid username or password," this means that the username or password is incorrect.

To fix this issue, make sure that you use the correct credentials. You can also reset the password, and then update the password in Settings on the device.

Check network connectivity

Teams Rooms must have access to all standard Microsoft 365 endpoints and meet the network requirements. Teams Rooms doesn't support proxy authentication.

If you don't see any sign-in attempts in sign-in logs on the Azure portal, the connection to the Azure sign-in endpoints might be blocked. In this case, verify that you're using the correct username, and check for network connectivity issues.

If you see successful sign-in in sign-in logs on the Azure portal, but the resource account sign-in still fails, try the following options:

1. Check if the resource account has valid licenses assigned.
2. Check if connections to Microsoft 365, Teams, or Exchange endpoints are blocked.

To troubleshoot network connectivity issues, you can use Network Monitor or a similar tool to collect network captures (you must switch to Admin mode to start the tool, then switch to the Skype user). Then, work with your network team to identify and fix the issues.

Check whether the room mailbox exists

Teams Rooms resource accounts must have a mailbox that's hosted on Exchange Online or Exchange Server. Otherwise, the Exchange service reports that no mailbox exists for the user during discovery.

To check whether a room mailbox exists, use one the following options:

• On the Teams Rooms device:

  1. In Event Viewer, go to Applications and Services Logs > Skype Room System.
  2. If you see Event ID 2001, check whether the description contains Exchange status : GeneralError.

• In sign-in logs on the Azure portal, you see a Success status, but Exchange doesn't return any user when using the acquired token to complete discovery.

To fix this issue, follow these steps:

• Verify that the account being used is the resource account and is password enabled.
• If an Exchange hybrid deployment is used, make sure that the on-premises mailbox is synchronized so that redirection works correctly. For more information, see Exchange Server hybrid deployments.

Verify that the resource account has a Teams license assigned

Teams Rooms devices must have a Teams Rooms Pro or Teams Rooms Basic license assigned. To check whether a Teams license is assigned, use one of the following options:

• Review the device logs.

  1. Download the device's diagnostic log files.

  2. Extract the downloaded .zip file to a folder, then go to the App\Microsoft\Teams subfolder.

  3. Open the Logs.txt file.

  4. If you see the following error message, this means that a license isn't assigned.

     errorCode: FailedAuthentication, errorStep: get_skype_license, errorState: licenseError

• In sign-in logs on the Azure portal, you see a Success status, but the sign-in fails when the process uses the acquired token to register the Teams service.

• Open a web browser, and sign in to Teams by using the resource account. If you receive the following error message, this means that a license isn't assigned.

  You're missing out! Ask your admin to enable Microsoft Teams for <Account Name>

To fix this issue, make sure that a Teams Rooms Pro or Teams Rooms Basic license is assigned to the account, and that Microsoft Teams app is also applied, based on the license. For more information about license assignment, see Assign Microsoft 365 licenses to user accounts.
