Prozesse in Microsoft 365 zum Einrichten von Office-Apps, zum Einlösen von Produktschlüsseln und zum Aktivieren von Lizenzen.
Thanks for reaching out. Do you already have the Microsoft 365 apps installed on your Android phone?
You do not need to add a serial number for mobile devices. Install Outlook, Word, Excel or PowerPoint from Google Play, then sign in using the same Microsoft 365 Single account. Your phone will show under your Microsoft account devices after you sign in. If you reach the device limit, remove older devices on the Microsoft account website and sign in again.
