Problem : Mail conflict resolution messages

We have a hosted Exchange 2007 with Outlook 2007 clients.  One client keep getting these synch messages that fill the mailbox space.  That laptop has been rebuilt for another reason so that mean Outlook profile has been rebuilt also.
Does that mean something is happening at the hosting company?  All they recommend doing is to rebuild an Outlook profile.  Any suggestions?

Solution : Mail conflict resolution messages

Regenerating the OST file (cached PST-type file that contains a copy of the mailbox).

The error message is basically saying that there was a conflict in a message stored locally and its copy on the server. This looks to be due to the fat that it was modified at different times (miliseconds) on the server to the local host. This could be indicative to a time drift, and probably shouldnt be worried about it. Basically Server always wins, and it will re-download the mail to cache if required.

Rebuild the OST (simply removing it will do, in their local profile under localsettings\application data\microsoft outlook or similar) and see if you still get them.
