Unfortunately when I tried your solution it did exactly what I didn't
want it to do. It wipped out all of the past entries so the history
is gone. Thanks for trying though.
It's possible you selected the series instead of the occurrance. It's fully
possible to change the times of one recurrance. I do it several times per
month. Changing the series, however, will do exactly what you describe:
regenerate the entire series so that past entries are also changed. A
recurring event is only a single entry in the calendar from which Outlook
calculates the individual dates on the fly and anything that modifies the
entire series will cause Outlook to recalculate.
