After migration from Ex2007 to Ex2013 SP1 - mailbox delegation settings: Warning "The object mydomain.com/TestUser1 has been corrupted, and it's in an inconsistent state"

Few users were successfully migrated from Exchange 2007 to Exchange 2013 SP1 server. However, migration for some users failed with error message: “Error: This mailbox exceeded the maximum number of corrupted items that were specified for this move request.”

Trying to resume failed migration batch within exchange admin center is producing the same error.

After some Googling around I have found this article “Corrupted Items and Mailbox Moves in Exchange 2010” (http://windowsitpro.com/exchange-server-2010/corrupted-items-and-mailbox-moves-exchange-2010)

I’m guessing that information in this article is quite relevant to the Exchange 2013 SP1 as well.

Base on the information from the article I’m trying to run following PowerShell command:

Get-MoveRequest -Identity "TestUser1" | Set-MoveRequest -BadItemLimit 20 | Resume-MoveRequest

Output from the command in exchange management shell doesn’t really tells me anything except yellow color warning about possibility of losing some items during the move because of BadItemLimit.

After a while I have noticed that failed status have changed to completed and the mailbox is in correct target database.

Checking properties for the freshly migrated “TestUser1” within Exchange Admin Center looks good so far except for the ‘mailbox delegation’ settings. When I click on it gives me scary warning:

Warning
The object mydomain.com/HR/Admin/TestUser1 has been corrupted, and it's in an inconsistent state. The following validation errors happened:
--------------------------------------------------------------------------------
The access control entry defines the ObjectType 'd819615a-3b9b-4738-b47e-f1bd8ee3aea4' that can't be resolved..

The access control entry defines the ObjectType '9b51a1ef-79b7-4ae5-9ac8-d14c47daca46' that can't be resolved..

What is this?! The word “corrupted” gives me shivers. How do I fix this? If I have too, I can delete this mailbox on Ex2013 and recover it from the backup back to the Ex2007 server but I’m hoping for the easy fix solution if possible.

Thanks in advance

"Corrupted" means Exchange cannot read it.
In most cases this isn't a problem with the mailbox, but the Active Directory account.
Look at the account in ADUC - I expect on the Security tab there are some accounts which are just the GUID - probably from deleted accounts. Remove them and then wait for replication to occur.

Yes, you’re right… I can see few unknown account there. Before I’ll remove them from the security tab I would like to find out who was using those account before.
If you are seeing the Raw GUID then you will not be able to find out anything because they are now orphaned objects. Removing them is the only thing that you can do.
