You won't find anything there. There were a few courses sporadically
available a few years ago from training centers, but none now that I know
of. That's one reason I wrote my book (see signature) at a relatively novice
level -- to try to fill the gaps.

Conferences that deal with Office programming generally include at least a
few Outlook sessions. Most Outlook developers that I know, though, are
largely self-taught. A lot of trial-and-error work is involved to find out
what works and, when it doesn't, devise workarounds. These forums can help
with specific questions.
