I manage something similar, and on a lot of occasions, it's helped me catch
where I've forgotten to take something off, something got rescheduled and no
one told me, or someone else goofed up the scheduling. In my case, I had a
second email created in Outlook (so two or more people could access all the
same information, including emails, relating to scheduling in case one of us
is out sick), and then I created a calendar for all the scheduling on that.
Then type some information on the scheduling like name of meeting, point of
contact, senior attendee, and resources required (i.e., teleconference). A
lot of times I'll just paste in the email I receive about the meeting as the
calendar appointment; that way, I have all the original information to refer
to. If Word is enabled as an editor, you can also do Insert>Object and
insert emails into the calendar for reference.
