Micro$opht IE (on XPee only) launches messenger by callto:gates or outlook by outlook:calendar protocols
For outlook there exists a wide range of other shorcuts as well. Just verify left pane of outlook shortcuts ...
try to open iframe with any of those protocols and you will get outlook open (or at least wizard to configure it will be called).
