It appears that months after an appointment is listed on my Outlook calendar,
the calendar is cleared. I'm not sure how much lag time, but I know I have
sometimes gone back say 6 months to reconstruct the dates of a meeting and
there are no appointments listed (except for reoccurring appointments, for
some reason?). Apparently, it clears appointments at some point when they are
6 months old or so? Is there a way to turn the clearing function off, or
maybe extend the clear date to 12 or 15 months? I can't seem to find anything
about this on MS Help. Thank you.
