Many of our users connect to SharePoint 2007 calendars using Outlook 2007. The calendars seem to randomly disappear from our users' Outlook profiles and they need to often be reconnected. We're also running Exchange 2007 if that matters. Has anyone seen this before or have suggestions on how to correct it?

Have these user checked the Don’t display this list on other computers I use option mentioned in http://www.endusersharepoint.com/2009/10/20/sharepoint-quick-tip-remove-outlook-connection-to-sharepoint/ ? Are there outlook roaming profile involved? Gu Yuming TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com

Thanks for the suggestions Gu. I'll give this a shot and see how it goes. Our users don't use roaming Outlook profiles but they do log into several different workstations including terminal servers that have Windows roaming profiles.

You are right, its' roaming user, not "outlook roaming profile", you must have already read these: http://office.microsoft.com/en-us/office-2003-resource-kit/configuring-outlook-for-roaming-users-HA001140269.aspx The "remote and roaming users" and the "Using Outlook with Terminal Services" section from http://technet.microsoft.com/en-us/library/cc179007(office.12).aspx
