The default location for the OST file is %localappdata%\Microsoft\Outlook, which is not included in the roaming profile. So unless the default location was somehow changed to be in %appdata%, the OST files are not being shared, and are unique on each computer (it would be best to confirm though by checking Outlook).
I would also check to see if any PST files exist on the network since this may be causing problems too. What do the pop up messages state? One area where roaming profiles do have problems is with multiple versions of Outlook - if you attempt to open Outlook on a computer with an older version of Outlook, it will likely fail/cause problems - Outlook problems are not backwards compatible from what I've seen. -Aakash Shah -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kurt Buff Sent: Friday, August 1, 2014 9:34 AM To: [email protected] Subject: Re: [Exchange] Outlook and roaming profiles Excellent. Thanks for the feedback. I agree on roaming profiles - we tried them in this office years ago, and it caused nothing but problems. That office seems to love them, however. We're working on trying to wean them off of them, but it's a definite layer 8 problem.
