How do I undelete, deleted appointment occurrence(s) deleted within an
appointment series??

If I delete the whole series it shows up in my deleted folder - so no
problem.

BUT if I delete say 1 occurence in a series that doesn't show up in
the deleted folder ;-(

Is there some way I can recover these?

Since one element of a series is not itself a separate item, I'm not
surprised it doesn't show up in the Deleted Items folder. I don't think
there's any way to recover it.
