  1. Iam on an office 365 home plan. When I look a the device listing to see my activated licences I am seeing the same device listed twice. Am i Safe to remove one of them or do I lose partial or complete licensing on that device?

    1. Hi Patrick, sorry for such late response. I think you may have already found your answer. You can remove devices from the list and add them again later, as long as you don’t cross the allowed number of devices.
