No messages, nothing in logs that I can see.

The process is running I can see it with ProcessExplorer, if a new
mail arrives the popup pops and the envelope is in the tray. I can
click the new mail icon in the tray read the mail, answer it if need
be, and the envelope goes away as it should.

If I start Outlook from Quick Menu then it starts immediately, I
don't think it allows multiple instances - that's fine by me, I only
want one. When I minimize I get nothing in the tray.

Well, I'm stumped. Have you customized the notifications in the system
tray? If so, does removing all customizations (i.e., always showing all
icons) change anything?
