Voicemail setup process for an individual user in Classic Teams.
Click on the ... icon in the main Team application Window (top right corner) and select Settings
In the Calls tab, select Configure voicemail
From there, you can Record a greeting and set various voicemail rules
Access Voicemail Messages
Voicemail messages left for an individual user will display in the Teams application. To navigate to your voicemail messages, go to the Calls icon and select Voicemail.
Voicemail messages are delivered to your email inbox. Microsoft Teams is actually referencing the message in your email so if you delete the message in your email, it will also be deleted in the Teams app. Users have the option to install the Microsoft Teams app on their personal smart phones to access to voicemail messages wherever they are. Pin numbers are not used in Microsoft Teams.
Note: Voicemail messages left on a department or mainline are only delivered to email, they will not appear in Teams.
There can be an instance where a Voicemail on Teams is missing or is unable to play. This can be caused when the call is spam from an external number. Keep in mind if the message was deleted in Outlook it will also be deleted in Teams.
