Using Exchange 2007 and Outlook 2010. We have a Public Folder set up to receive emails from an outside source that many of my users access. We just recently made the switch to new machines with Office 2010. I have one user who gets a Public Folder Conflict Message whenever he opens an email in that Public Folder and the conflict is with himself (the conflict message shows his user name as conflicting with itself). It does this for every message he opens except for the last one. It does this every time without fail. No other user has this issue. Any ideas?
I should add that this problem started with the use of his new Win 7 machine with Outlook 2010. Prior to this using Outlook 2003 on a Win XP machine, there were no issues.
