"Unable to establish a secure connection to mailbox_servername because the server name or IP address does not match the name or IP address on the server's certificate. If you continue, the information you view and send will be encrypted, but will not be secure."

I have a test Exchange account and I'm still getting the error too. I'll
report and let them know. My understanding it has something to do with the
certificate.

As of SP1, Entourage looks for the AutoDiscover xml file.

If you take a look in the Exchange 2007 AutoDiscover whitepaper, you'll see
it uses two URLs to look for the autodiscover xml file. Both URLs are based
off your SMTP address in your email address - it doesn't matter what server
you connect to.

You can take a look at the AutoDiscover whitepaper here:
<http://technet.microsoft.com/en-us/library/bb332063.aspx>

Here is an example for Joe Blow. :)

In this case, all email addresses from Joe's server end with @blow.net.
This means we will connect to autodiscover.blow.net and blow.net looking for
the xml file. If Joe's server happened to host another email domain and
gave out email addresses ending in @joesfriends.com, then Entourage would
connect to autodiscover.joesfriends.com and joesfriends.com looking for the
Autodiscover xml file.

The actual urls that we connect to in this case are:

https://autodiscover.blow.net/autodiscover/autodiscover.xml
https://blow.net/autodiscover/autodiscover.xml

Since the first one doesn't exist (no DNS record), we try the second one.
But the cert at that the second location does not have "Blow.net" on the
cert, thus you get a host name mismatch error and Entourage shows the
dialog.

The fix in this case would be to:

1) Add Blow.net to the cert located at: https://blow.net
2) Create a DNS record for autodiscover.blow.net and point it at the same
server as rapier.blow.net as well as add autodiscover.blow.net to the
certificate as well as rapier.blow.net.

Let me know if this helps.
