The system drive failed, so I installed new drives, installed windows & exchange, got exchange up and running with the original edb's. Now, when I start the ES, it starts successfully, then gives the following error, then stops successfully.
Event Type: Error
Event Source: MSExchangeES
Event Category: General
Event ID: 5
Time: 12:00:00 AM
An unexpected MAPI error occurred. Error returned was [0x80004005].
Any ideas on how to fix this? I had some issues originally with the MTA & IMC, but I changed the required entries in the registry and they began to work.
