When I am trying to update appointment(with document attached) for sharepoint calendar from outlook 2007, the appointment disappearing for around 45 second and then get updated, and I get the error message below, is there any hope to get it updated without the delaying “task sharepoint reported error 0x00000000 failed to copy one or more items because some are not compatibale with sharepoint the failed items were moved to your local failure folder ans replaced with copies from the server” if i did the update from sharepoint there is no issues and the item will get updated at outlook directly

Hi, refer http://support.microsoft.com/kb/926440 which gives following workaround To work around this issue, use one of the following methods: Do not create and send a meeting request when the SharePoint Calendar list is the active calendar in Outlook. Instead, create and send a meeting request when your default Calendar folder is active in Outlook 2007. In the SharePoint Calendar list that you add to Outlook 2007, create a new appointment instead of a meeting request In addition you can use 3rd party tool to sync Outllook and SharePoint two side Colligo Contributor 4.0(http://www.colligo.com/) allows two way sync of SharePoint doc libraries, standard and custom lists, metadata and views. Enables users to create new documents from content types. Extensive metadata handling capabilities. Integrates directly with Microsoft Outlook email. Three interfaces: a rich standalone client, a Windows Explorer plug-in and add-in for Microsoft Outlook. Regards, Pratik Vyas | SharePoint Consultant | http://sharepointpratik.blogspot.com/

ACTUALLY I CHECK the link BUT IT does not solve my issues, we have a lot of events scheduled under our sharepoint calendar and we should update the event direct for out look.
