Contacts in Teams not showing work phone number

Hi,

In the contact card you will see numbers from Active Directory. So If you check in Azure Active Directory or Windows Active Directory you can see the number that Teams will show in the contact card. Teams will show Office Phone if that exists, if it is empty like in the example below Mobile phone will be shown instead. If both of them are empty no number will be shown.

The Work number is that the number you assigned to the user in Teams (LineURI)? That is not shown if you don't enter it in Office phone field in AD. So If you want to show the work number in the contact card enter it in the Office phone field, you could create a Powershell script that do that for you.
