Hi guys,

Help!! I've been running Vista for a month without issue except for e-mail
compatibility. We connect to Exchange via HTTP/RPC. Everything works great on
XP SP2, but I cannot make Vista connect no matter what I try.

Our certificate is installed as a Trusted Root Authority. Everything is set
up perfectly for the profile. Outlook is reaching our server so connectivity
is not a issue. Once it hits the Exchange server, it doesn't seem to know
what to do and as a result I receive the infuriating message:

"The action could not be completed. The connection to the Microsoft Exchange
Server is unavailable. Outlook must be online or connected to complete this
action."

If I try outlook -rpcdiag the RPC Dialog doesn't even tell me which network
protocol it is attempting to use. Ethereal doesn't seem to work with Vista so
I can't inspect the packets that way...does anyone have any ideas?!

Thanks in advance!!

Regards,
Mike.
