Adding a domain (@RTHV) user to an M365 group

1. Open the M365 admin center portal. Navigate to "Teams & Groups" on the left hand side and select "Active teams & groups".

   
   
   

2. Find the group you would like to add the user too and select it. Click on the membership tab.

   
   
   

3. If you would like to add them as an owner, click on "Owners" and "+ Add owners". If you want to add them as a member do the same but in the "Members" tab. Owners have admin access for the group and should be limited to a few users that require this access. 
   

   
   
   

4. You can then enter either the name or email address of the user then click "Add" at the bottom of the page.
