General information on M365 guest accounts at KIT
External users who are invited by KIT employees via their email address or who are granted access to data in MS Teams are automatically assigned an M365 guest account.
Note: This M365 guest account should not be confused with the GuP account for guests and partners at KIT. The M365 guest account is intended solely to provide access to the M365 tenant for KIT employees, so that they can collaboratively access KIT-shared content in the Microsoft Cloud.
What should users with an M365 guest account keep in mind?
To access shared divisions at KIT, you must sign in to the M365 guest account. KIT requires multi-factor authentication (MFA) for these guest accounts. Below you will find instructions for setting up the required multi-factor authentication and for logging in with an M365 guest account. Depending on which Microsoft account the invited external users use to log in to the Microsoft Cloud, there are different step-by-step guides available.
How does an external user sign in to an M365 guest account?
If you're unsure whether the invited guest has a Microsoft account, the following checks can help:
| Registration for ... | Gastkonto ohne Microsoft-Konto | Gastkonto mit persönlichem Microsoft-Konto | Gastkonto mit Microsoft-Geschäftskonto einer anderen Organisation |
| myaccount.microsoft.com | Registration is NOT possible | Registration is NOT possible | Registration is available |
| account.microsoft.com | Registration is NOT possible | Option to request a code to log in | Registration is available |
