I'm using Outlook 2003.

I have a client that uses recurring appointments to do field work.  The
appointment is set up without an end date, and details are filled into each
appointment as the appointment takes place.  However, when a string of
appointments ends and an end date is set, all the details are lost.  The
individual appointment entries revert to the data in the very first
"original" appointment across the board.

Is there a way of changing end date or recurrence information without losing
any modifications already made?
