Had a strange issue where Outlook just went off into space when I was trying to compose a reply. Restarting Outlook didn't help, I had to reboot the whole computer. Post-reboot, Outlook was slow, but it did work. Seems OK now.
This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
