I have a mailbox that I tried migrating from exchange 2007 to exchange 2013. I received the error, "MigrationPermanentExcepti
on: Active Directory property 'homeMDB' is not writeable". I googled the error and applied the solution from http://www.techieshelp.com/exchange-2013-active-directory-property-%E2%80%8Ehomemdb%E2%80%8E-writeable-recipient/
. I then re-ran the migration and received an email telling me that the migration completed successfully. However, the mailbox is still on the exchange 2007 server's mailbox database. It didn't move at all. Any assistance would be appreciated.
