We keep experiencing the following, but we can't figure out how to reproduce it:
A person using Outlook 2007 w/ ZCO 6.0.5 creates a calendar appointment and invites 2+ attendees. Within 5 minutes, the calendar item disappears from the organizer's calendar, but remains on the invitee's calendars.
This is occurring as frequently as every 10th appointment scheduled, but we can't figure out what is causing it!
Is anyone else out there experiencing the same?
