Exchange 2013 Active Directory property ‎homeMDB‎ is not writeable on recipient

When trying to migrate users from Exchange 2007 to Exchange 2013 you may see the following error below:

 Error:MigrationPermanentException: Active Directory property ‎'homeMDB‎' is not writeable on recipient ‎'domain.local/users/employee.smith‎'. --> Active Directory property ‎'homeMDB‎' is not writeable on recipient ‎'domain.local/users/employee.smith‎'.

With many Exchange issues the solution is to set the correct permissions to allow Exchange to migrate the mailbox.

To resolve this issue follow these steps:

1. Launch Active Directory
2. Click on View and select Advanced Features
   
   
   
   
   
3. Now location the users mailbox you are having the issue with and select properties
4. Now click on the security tab
5. Next select Advanced
   
   
        
6. Now place a tick in the "Include inheritable permissions from this objects parents" box and click OK
7. It may take a few minutes for this change to take effect but once it has you should be able to migrate the users mailbox without any problems.
