When migrating or adding a new user to Exchange 2013, I get the following error when going into the Mailbox Delegation section in the Exchange Admin Center.
The object <Object CN> has been corrupted, and it's in an inconsistent state. The following validation errors happened:
The access control entry defines the ObjectType 'Object GUID' that can't be resolved.
I have done the following to try and resolve the GUID
Searched via LDP, ADSI, ADUC, Repadmin, with nothing found. I've converted the GUID from string to hex and searched with still no luck.
I get the identical error when running a Get-ADPermissions on the object as well.
There are no inheritance blocks on the object or OUs.
I've opened a Premier case, but wanted to ask the community if they have seen this or had any suggestions. As of right now, Exchange 2013 is the only app that can see this orphaned object.
