Hi, I am using WebDav protocol to create/send/delete Appointments/Meeting requests on Microsoft Exchange server 2003 SP2. I see that every day few appointment items vanish from the organizer's calendar without anyone explicitly deleting them. The items get deleted in bulk i.e, 15 - 20 every day. The software which creates the meeting requests/Appointments is written in Java and operates under Solaris 10 operating system. This is also happening with few attendees who say their calendar items are missing once they accept them. Please let me know if there is any other information needed. When we removed write permission to other users on the organizer's calendar, the issues seems fixed for organizer's calendar. however, the issue still exists on attendee's calendars as we cannot restrict the sharing of their calendars. Except this clue , we could not get any other clues. Note: We don't have any clue about the relation between missing calendar items and sharing calendars. We are sure that they are not deleted manually. Advance thanks for the help. Ramana
