Powersehll Beginner - Add multiple Users to group

AxelRumkorf 

Based on the fact that you are a beginner Powershell, and that you need an easy way to fix this, I suggest you take a look at Power Automate and the Azure AD connector. 

You can easily create users based on CSV lists, and add them to groups/teams as well.

Also, take a look at dynamic groups. You can create groups based on AAD properties, such as department, job title, and location. This can also be used for on- and offboarding. Just by changing the property of the users, the group membership will be updated.
