It's likely the service pack difference between the two servers.

We are moving some users a new server (better hardware) which has Exchange 2003 SP2. When the users open outlook they receive "cannot start Microsoft Outlook unable to open the outlook window the set of folders could not be opened". Outlook then quits. They do not have psts. They can access their mailbox fine through OWA. If we go to each user's machine and re-do the profile it works. This is not happening to all the users, just a handful. We have synchronized the Domain. We have told RUS to rebuild. nothing seems to help. Everything I found on google pointed to pst issue. Any suggestions? Any idea what is happening?
