We're running Office 2007 SP2 / WinXP Pro OS / Exchange server environment and experiencing a challenge with just one workstation. This one workstation is having an issue where Outlook crashes unexpectedly (with no error reported) upon viewing another person's calendar. It happens sporadically, we can't seem to link any particular events - or calendars - with the crash. The user is then able to restart Outlook with no problem. Event Viewer does not provide any helpful info. We know it's not a problem with the user's local PC as the problem has occurred when using multiple PC's.
