Mailbox Move Error ‘Active Directory property ‎’homeMDB‎‘ is not writeable’

KB ID 0001326 


I was migrating some mailboxes form Exchange 2007 to Exchange 2013 today, when once again this happened;

Error: MigrationPermanentException: Active Directory property ‎’homeMDB‎’ is not writeable on recipient ‎’’. –> Active Directory property ‎’homeMDB‎‘ is not writeable on recipient


I can’t believe there’s no fix for this yet! This is being caused by exactly the same problem as we had back with Exchange 2007 and Exchange 2010 (see link below)

Exchange Mailbox Move Error – (INSUFF_ACCESS_RIGHTS)

So to fix, open ‘Active Directory Users and Computers’ > View > Advanced Features.

DSA Advanced View

Security tab (if you can’t see it, advanced features is not on) > Advanced.

User Security Tab

Enable inheritance > Apply.

User Security Allow Inheritance

Yes > OK > OK.

Allow Inheritable Permissions

Now retry your mailbox move.

To Find out who else will be affected: Run the following command;

Get-ADuser -Filter {admincount -gt 0} -Properties AdminCount | select name

 PowerShell find Users AdminCount
