We are having a problem with a new email project. We have converted a client over to Hosted Exchange from their old POP email. We set them up with calendars under the main account for the manager so she can control all of the calendaring. She would like to have her assistant added to all appointments in her calendar. This isn't a problem for future appointments, but they have thousands of existing appointments. Is there a way to add the other user as an attendee to all of her existing appointments. We really don't want to edit 2000+ appointments.
