So I did some tests and found that if I removed the filter and exclude
recurrences, I can see everything in the Calendar. Subsequent runs do
not add any additional items. So #1 appears that it has something to
do with recurrences. As long as the ID's are recorded somewhere,
that's great. I don't care whether I can see them or not. If I can
create an ID for each occurrence and record it in Outlook somewhere,
that's great.

Issue #2 is still an issue. I need to find a way to eliminate those
items from being recreated. Why are the ID's not being read for
them?
