Remove assigned managers of users
Use this button to unset the manager of selected users in Azure AD.
1 - Select users in the grid.
2 - Click on Remove Manager.
3 - Continue to unset the manager without loading the current information first. The manager info will appear green and empty in the grid as a preview before you save your changes.
If you want to see information about the current managers of the selected users before you remove them, you may want to ‘Load info’ first.
