## Solution

1\. In Activate Studio - perform a Verify on the Roles and ensure there are no OU or User References to objects that have either been removed from AD or moved to another location directly in AD. The Verify will highlight any issues that need to be fixed.

2\. If you have any references to OUs that have been moved, then perform a sync on the **Users** role once you have removed the bad references.
