We have an Exchange 2007 SP1 Server, and a mixture of Outlook 2003 and Entourage 2004 users. We user the resource calendars for our meeting rooms and most of the time everything is o.k., but we sometimes have issues where an outlook user can either add an entry to the meeting room, by booking it manually rather than inviting it, and once done for say an hour or two. Some of the time, this booking only shows for half an hour on the macs, but shows for the full time on the PC's. We also get issue where if a booking has been dragged to another day on a PC to be moved, it may not show on the mac calendars. It's not every time and I'm scratching my head as to why as people seem to be adding entries correctly. Any ideas
