    • Run the Teams Voicemail connectivity test.

      Both administrators and non-administrators can run the Teams Voicemail connectivity test in the Microsoft Remote Connectivity Analyzer tool. This tool is used to troubleshoot connectivity issues that affect Teams. The connectivity test determines whether a user account meets the requirements to access voicemail, and whether the Teams client can retrieve and display voicemail messages.

      Note

      The Microsoft Remote Connectivity Analyzer tool isn't available for the GCC and GCC High Microsoft 365 Government environments.

      To run the connectivity test, follow these steps:

      1. Open a web browser and navigate to the Teams Voicemail connectivity test.
      2. Sign in by using the credentials of the affected user account.
      3. Enter the verification code that's displayed, and then select Verify.
      4. Select the checkbox to accept the terms of agreement, and then select Perform Test.

      After the test is finished, the screen displays details about the checks that were performed and whether the test succeeded, failed, or was successful but displayed a few warnings. Select the provided links for more information about the warnings and failures and how to resolve them.

    • If you're using the GCC or GCC High environment, see Control routing of calls to Cloud Voicemail.
