I have installed a new sbs 2003 server and built 7 new XP workstations on a new domain. This is replacing a workgroup environment. I have created all 7 users accounts fresh on the new server with exchange mailboxes. I have then imported the current pst files into the exchange profile. This worked fine on two workstations and all the mail, contacts etc were imported successfully. The rest of the workstations all returned this message. I am using the pop3 mail connector to download mail from a linux box into exchange, as previously all mail was pop collected down into local psts.
