Delete Users or Groups (Master Data Services)
Applies to: 
SQL Server - Windows only
Azure SQL Managed Instance
Delete users or groups when you no longer want them to access Master Data Manager.
Note the following behavior when deleting users and groups:
If you delete a user who is a member of a group that has access to Master Data Manager, then the user can still access Master Data Manager until you remove the user from the Active Directory or local group.
If you delete a group, all users from the group who have accessed Master Data Manager are displayed in the Users list until you delete them.
Changes to security are not propagated to the MDS Add-in for Excel for 20 minutes.
