How to Login to Microsoft 365

The Microsoft 365 cloud service offers employees of the University of Mannheim the option to use various applications for digital communication and collaboration.

We have set up an extra instance for students. For more information, please see M365 for students.

Now we would like to show you how you can sign in to Microsoft 365 and access the individual applications.
