shared calendar issue
 

We are using Outlook 2007. One of our users has read/write access to her
manager's calendar. When she books a meeting from her manager's calendar,
she always gets a message saying "this appointment already exists in calendar
server". The appointment then goes into her managers' calendar but she does
not get notificationthat the appointment has been emailed to attendees (it
doesn't go in her sent box).

Any help appreciated,
