Outlook 2007 appointments being removed from calendar
 

We have a handful of users supporting VP's, and have editor permissions to
the VP calendars. Periodically a recurring meeting will be moved to another
date or time, and when meeting attendees accept the invitation, it doesn't
reflect on their calendar. We believe this started happening after a
migration from Office 2003 to Office 2007. In that same timeframe, we
upgraded our Blackberry servers to the most current version. I mention this
because I had a user on the same recurring meeting that was moved accept the
meeting in Outlook, but her blackberry doesn't reflect the meeting change.
Any assistance would be greatly appreciated. Thanks in advance for any light
you can shed on this issue. thanks,
