Entourage 2008 Web Services edition (13.0.3) and " Unable toestablish a secure connection" error

[Bill Bryson]

One of our users had his Entourage 2008 upgraded to EWS (13.0.3). He is
using Leopard 10.5.8. Since the upgrade he is getting an error/warning
message after he provides his login credentials:

"Unable to establish a secure connection to exchnlb.txstate.edu because the
server name or IP address does not match the name or IP address of the
server's certificate."

This looks very similar to an issue that was address by the 12.1.2 update.

There are no reports of other users which this issue. I use the same
version of EWS as the user.

There is an ability to capture info in a log but I don't think in this case
that will accomplish much. See:

Also consider the discussion (a bit dated) at:

age-2008.aspx

From the discussion, it appears this had to do with the autodiscover process
in conjunction with Entourage 2008 BEFORE 12.1.2.

I appears that it has returned potentially for EWS users.

"Unable to establish a secure connection to exchnlb.txstate.edu
because the server name or IP address does not match the name or IP
address of the server's certificate."

If I connect to <https://exchnlb.txstate.edu> in a web browser then I
receive an error message stating that the certificate is invalid (host
name mismatch).

From what I can tell, Entourage is reporting the problem correctly.
