Provide instruction on how to check your voicemail in Microsoft Teams
To check your voicemail, choose Calls > Voicemail.
Select a voicemail in your list and use the playback controls to listen to the recording or read a transcript (if it's available).
To call someone back, select More options > Call back. You’ll be able to check the status of anyone with a Teams or Skype for Business account to see if they’re available for a call.
Note: If you don't see Calls on the left side of Teams, you don't currently have an Enterprise Voice license, and things like voicemail and call history won't be available yet.
