Recently changed from Exchange 2003 to 2007. We have a shared calendar set up that lists appointments for two people (I know that's a strange way of doing it, it's just the way it's always been done!). Appointments are listed on the left for one person, on the right for the other (see the attached image).
In OWA with Exchange 2003, these appointments stayed where they were when you edited them - but with 2007 they are listed alphabetically, meaning that if you edit an appointment, it may swap places, unless you make sure they're always alphabetical.
Short of always typing e.g. "1" on the left and "2" on the right, is it possible to get the appointments to stay in position? Of course, the proper way to do it would be a separate calendar for each user, but that would mean OWA users won't be able to view both calendars in the same window.
Hope this makes sense - look at the image if not!
