Box 1: Microsoft Teams

Maintenance supervisors must not have access to Dynamics 365 Customer Service. The supervisors must be able to communicate with the contracts team about contracts.

The Expense management mobile workspace lets users capture and upload a receipt, so that they can attach it to an expense report later.
