I rarely suggest third party software in here, and this is a perfect
example of why not :-(
I don't know anyone at MAPILabs - looking around their support pages,
they claim to reply in 48 hours, which may be too late for you. I guess
you could always "prod" via their fax number.
As for the problem itself, I don't have any good suggestions, but
a. 80004005 seems to be caused by a number of things, but seems often
to be related to a permissions issue. I suppose if I were using
Outlook+Exchange server, I might try to do stuff like ensure my COntacts
were in a local folder - that kind of thing.
b. If you haven't yet had a good look around Outlook Tools->Trust
Center->Add-ins, that would probably be my starting point. You may also
be able to get some info. from the Windows Event log.
