This group is synchronized with an Active Directory Group. If you want to add or remove specific users, turn off this synchronization.

Today we are writing about below task, I have created new site collection and synchronized user from our active directory and we want to make a user as Project manager for site collection.

To add a user as Project Manager we need to add users under the Manage Groups from PWA settings

This group is synchronized with an Active Directory Group. If you want to add or remove specific users, turn off this synchronization.

Below are the solution step by step:

• Login to site with admin account and click on setting from right side of site page.

• Now click on a Groups of Project manager from Manage Groups wizard page

• Now, we will seeing on this page the above error message is showing down the Users box, here we need to see group will be added to sync from below option

Active Directory Group: Choose the Active Directory Group that will synchronize with the current group.  

• Once remove Groups from the Active Directory Group, and we will see users will be activated to add in the respected Groups.

• Now add the users to groups and save the same and we can verify users are added and can access site with Respective Roles.

Thanks ☺
