At our site we had this problem before we upgraded to Exchange 2013 CU6 after was installed problem was fixed. About one month ago we applied some Windows Updates to the Exchange Farm 1 CAS Server, 2 Mailbox Server running in a DAG, all servers are Windows 2012. After the windows updates were applied the Remote Server returned '532 5.3.2 STOREDRV.Deliver; Missing or bad StoreDriver MDB properties'Remote. error has come back. Is there a known issue with a windows update that would cause this? Would upgrading to CU7 fix the issue again?
