RPC over HTTPS on Vista and OL2007 not working

[Guest]

I tried the usual routing in getting my Vista Beta 2/Outlook 2007 Beta 2 to
connect to our office exchange server.

First, downloadling a cert with IE7 is a real pain because you don't get the
usual option to 'View Cert' as it tries to protect you from all that jazz. I
got around that manually.

However, even after I configure the HTTPS proxy etc, after the first
username/login prompt, Outlook tells me it can't communicate with the
Exchange server. In detail, the message is:


The connection to the Microsoft Exchange Server is unavailable. Outlook
must be online or connected to complete this action.


The pause is there which leads me to think it gets to the proxy and
establishes the first part. But after that - it fails very fast.

Any thoughts? I'm going to try this on XP to see if its Vista doing it, but
the combo is what I'm going to be running throughout the office next year so
I thought I'd chime in early on this one.

it's vista because rpc/http works fine in outlook 2007. Are you inside the
network or outside? Are you using NTLM or Basic auth? (It connects just fine
using HTTPS inside my network.)

I'm outside the Network using NTLM.

This same setup works fine on an XP machine using Office 2003 from my
location so I know it's not a firewall/network issue.

I'm suspecting it's something with Vista and how it uses certificates or the
like. I tried to run it using 'outlook /rpcdiag' and it prompts me for my
user/pw to the Exchange server as it should. But then it errors out with the
same message as below.

Did anyone find out what was wrong with this? I'm having the same
trouble (however, I am installing Office 2007 on an XP mamachine, not
Vista?)

Thanks in advance

i have the same problem:
on the same pc i've win xp + outlook 2003 and vista + outlook 2003
the setup is the same, i installed my certificate
i works well with xp, not with Vista...
if somebody knows...

I have the same problem with this configuration:

Windows Vista RC1 (build 5600)
Office 2007 B2 Technical Refresh
Exchange 2003 SP2
A auto-issued SSL Certificate

I'm trying to understand if the question is the Vista/IE7 CRL verification,
because I get an error also visiting my OWA ssl site (Certificate Warning:
the CRL could not be verified). I tried both NTLM and Basic Auth, and various
network configuration (local, outside, PPTP VPN, site-to-site VPN). OL2007
only works in standard mode, not RPC over HTTPS.
It seems the same problem I had when I forgot to insert the CA certificate
of my certification authority in the Trusted CA Root.

Of course, with no beta apps (WinXP SP2, OL2003 SP2, IE6) everything works
fine.

Any ideas on how to turn off CRL verification on vista/IE7?

Thanks in advance.

I have this same issue with Vista RC1 and Office 2007 B2 technical refresh.
It worked fine with Vista Beta 2 and Office 2007 Beta 2.

While trying to connect, I ran netstat -an at a command prompt and it showed
that I was trying to use port 135 (netbios) for the SSL connection to the
exchange server instead of port 443.

I have the same problem with this configuration:

Windows Vista RC1 (build 5600)
Office 2007 B2 Technical Refresh
