How can I use M365 / office on my device?
The latest version of Office is now called Microsoft 365.
Open an Office program (e.g., Word or Excel) and go to File -> Account.
Click "Sign in" and sign in with your Microsoft 365 account.
Please note that after the login, you will be asked on a desktop computer whether you want to use the account everywhere on your device.
- Uncheck the box next to “Allow my organization to manage my device” (1).
- Then click on “Only this app” (2).

- In this dialog box, select the blue text “No, only this app” as well.

How do I add my device?
Simply log in to one of the apps. On most mobile devices, the device will be entered directly into your M365 account.
On a desktop device, you may be asked if you want to use the account on the entire computer. If you accept this, the computer will be listed in your M365 account.
You can view this under “View account” (via your name and profile picture). Go to Devices in the menu. Here you will find a list of all devices that you use with this M365 account.
How do I remove my device from the account?
For Windows devices
Go to Settings > Accounts > Access business, school, or university account.
Select your Office 365 account (vorname.nachname@uni-hamburg.de) and click “Disconnect.” In Windows, the link is created for each user profile.

Then open any Office program (e.g., Word) and go to File > Account (or Office Account in Outlook) > Sign Out and close all Office programs.
With iOS and Android
You can use the Microsoft Authenticator app and select Settings > “Register device and unregister device.”
