How do I add and remove users from outside oraganisation?

Hi  ThomasWeppler ,

You need to go to the Microsoft 365 admin center and find User to delete

Microsoft 365 admin center - Overview - Microsoft 365 admin | Microsoft Learn

Refer to:Manage guest access in Microsoft 365 groups - Microsoft 365 admin | Microsoft Learn

Hi  ThomasWeppler ,

Clicking on the yellow label will bring up Delete a user.

For the message "give guest PowerBi pro licens", you can see the following link:

Distribute content to external guest users with Azure AD B2B - Power BI | Microsoft Learn
