When I try to import a PST file from Outlook 2003 using the exmerge tool it fails with:
Error configuring message service (MSPST MS) (MAPI_E_EXTENDED_ERROR) (CMapiSession::CreateEMSPSTProfile)
I relize that this is because of the new Unicode PST format that Outlook 2003 uses. I can successfully import a PST in the 97-2002 format.
The problem is that I don't want to manually export/import all of the messages, etc in the format before importing with exmerge.
I also ran across another solution: open Outlook 2003 with the Exchange mailbox connection open. Then run File -> Import the messages from the PST file into the Exchange mailbox. Or, open the PST file and manually copy the messages, etc that the user wants to keep.
Again, the problem is manually doing this for each user. I don't have the time to do so, and many of the staff would not be able to do this themselves.
We are moving from a hosted mailbox service (with POP & SMTP) to our own server. The messages are deleted from the server upon arrival in Outlook, though, so any solutions relating to the previous service won't work, either. I'm just providing that as background info.
So my question becomes this: surely there is some automated way to import messages from Outlook 2003 into Exchange 2003 mailboxes. Any ideas?
