Hello, Is there a way of reducing the refresh/expiry time of open MAPI sessions on Exchange Server 2003? We have a wireless network here and from what I can tell, if the wireless drops out while Outlook is open, it will maintain that MAPI session and start a new one. Users eventually hit the MAPI session limit. I'd like to find a way of clearing these sessions without resorting to restarting the Information Store service. And I would rather not increase the limit of MAPI sessions, or adding them to the View Information Store Status permission. Is there any way? Thank you. Bobby

Have you applied W2003 SP2 on the box, then http://msexchangeteam.com/archive/2007/07/18/446400.aspxcould help you. W2003 SP2 introduced some new features and sometimes they dont play well. Turn them off and see if things get any better
