I'm trying to get a user set up in our office. He has moved here from another office so I want to download his mail from his old office Exchange server. I was thinking it would go something like this... - logs in and pulls all of his email down from the old office Exchange server - I contact the sys admin to delete his email account from the server - I Sync up both mailservers - I create his mail account on our server - he logs into our server The problem is, when I try to log in and pull all of his email it says... Unable to open Outlook.ost. You must connect to your Microsoft Exchange server at least once before you can access bla bla bla running Office 2000 Pro on Windows 2000 pro Exchange 5.5 Anyone seen this before? Nothing on Technet that I could find. Anyone know a good place to find an answer to this?
