I have 2 users that use the same computer during the day. User 1 works fine in outlook 2003 while user 2 has slow connectivity in outlook only. It freezes up periodically when moving from inbox to contacts, etc. I even put another computer in for these 2 users and it does the same thing. I can't figure out why it would work for user 1 but not user 2. All settings are the same, outlook is in cached mode. I recreated the ost file for her and it still freezes. I even took her out of cached mode and it does the same thing. The os is windows xp pro going back to exchange 2007 svc pack 2. I have 100 users on the network and this user is the only one with issues. Her mailbox is 1.5 gb's, which is small for my org. I rebooted exchange, still didn't fix. I'm lost on this one, please help!
