I have an Exchange 2003, MOSS 3.0 and Office 2007 implementation and seem to be able tosynchronizeSharepointcalendar items with Outlookwith only one exception. When a calendar item is added from the Outlook client it sync's immediately with the Sharepoint calendar.However when deleted on the Outlook client the item is not removed in Sharepoint.If I do the reverse, and remove on the Sharepoint side it will sync properly and remove from my client. Is there an Exchange setting that could possibly prevent the delete from the Sharepoint calendar when executed from an Outlook client? Couldthis be a bug?

any solution to this...i am encoutering the very same issue now with a new sharepoint site about to go live. Thanks Rich

Rrenes, It may be an issue with the user not having permissions to delete from the sharepoint calendar. Also, it might be issues with the SP Calendar and the Outlook Calendar being open at the same time. Make sure that Outlook is not in Cached mode and when you do a Send and Recive, make sure that it on all groups as they may have setup specific Send/Recive Groups. Lastly, ensure that Outlook has all its updates.
