Some of my users on our LAN are getting the password prompt in their Outlook about every 2 hours. Our Exchange 2007 server is using Windows 2003 and we are on a Windows 2003 active directory domain. Most of my users are using Outlook 2007 on Windows XP SP3. What is confusing is only certain users are getting the password prompt. Everyone else is connecting just fine. I have been troubleshooting this for a while now. Please help!
Software/Hardware used: Outlook 2007, Microsoft Exchange 2007 on a Windows 2003 server
