Exch 2007 Outlook Anywhere fails to connect
We have a client with Exch 2007 where we have installed the UCC (we have done this for many clients, OA/autodiscover works) and we cannot get outlook anywhere to connect via autodiscover or manually configured. External DNS is correct with A autodiscover.client.com. We believe the problem is that their www record is at their vendor's webserver and testexchangeconnectivity FINDS an autodiscover xml at that site. That then fails on a Cert name mis-match.
On the second step (autodiscover.client.com),
We do not think OL gets past the first cert name mismatch to our good cert.
We even tried removing the DNS A record autodiscover.client.com and adding the srv record, but thats checked last and we think autodiscover stops on first step. Any way to bypass the first check on domain.com or other ideas?
Thanks!

Yes, thats the problem, the vendor that hosts our client's website does have THEIR ssl and ExRCA sees that first and my clients Exch ssl second pass. We have contacted the vendor to see if they can do a "workaround", not sure that that would be?
The website https://client.autodiscover.com returns a 404 with file paths. We have no access to the site itself except through the vendor that hosts it.

Probably worth confirming to make sure, but it sounds like you may be a bit stuck.
edit the hosts file on a client PC to override the public DNS, as shown below. Try the autodiscover again and see if it works. (remember to put the hosts file back as it was when you're done...)
Add the root of your domain to override the public address pointing to your website.
replace 89.9.9.9 with the external IP of your own mail server.
If you try this and it works then you have confirmed that the public website is the cause of the problem.
If it still doesn't work you can now do further testing on this PC knowing the public website isn't the cause of failures.

Totallytonto: From their vendor: Public DNS chang, do you think this will work?
"The solution I can think of is they keep “www.domain.com” (A Record) pointing to the VIP “<vendor website ip>”.
They redirect “domain.com” (Parent A Record) to their own web server.
Then their webserver can refuse SSL port 8080 and redirect HTTP 80 traffic to “www.domain.com”.
This should get Outlook Anywhere to move to the next step."

seems a bit of a faff, but it's worth a try.
Did you test it using the hosts file?

Yes, and it still fails. We are thinking we will leave the autodiscover.domain.com A record and change the partent domain.com to their Exch outside ip.
We also think the paragraph should have been 443 not 8080 and web server should read Exch server?

if it fails with the hosts file amendments it suggests the website isn't the problem.
Agreed.

As long as the root domain responds to autodiscover requests you're not going to find a way around it. That comes above the other options in the list of autodiscover attempts so you'll have no choice but to look into it.
does the website serve https? does it have an autodiscover folder?
