We have an Exch 2007 client where we have installed the UCC (we have done this for many clients, OA works) and we cannot get outlook to connect via autodiscover or manually configured. We believe the problem is that their www record is at their vendor and testexchangeconnectivity FINDS an autodiscover xml at that site. That then fails on a Cert name mis-match.
On the second pass, testexchcon DOES find our valid 2007 cert and all passes.
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?
