Exchange 2010 Out of Office not working externally

I cannot seem to figure out why my Exchange 2010 server won't send out of office requests to external emails.  I have checked Autodiscover by using and it tests ok.  I have set allow external out of office in the organization hub transport, remote domains tab.  I have selected the 3rd option: Allow external out-of-office messages and legacy out-of-office messages (configured by using Outlook 2003 or earlier clients, or configured on Exchange 2003 mailboxes

However the emails are not going externally.  The only error I have been able to find thus far is when I run the Test-OutlookWebServices -ClientAccessServer server command, I get the following in the ouput:  

RunspaceId : e398167d-ff3d-4745-83ce-2edf3c36033e
Id         : 1104
Type       : Error
Message    : The certificate for the URL https://server.xxxxxxx.local/Autodiscover/Autodiscover.xml is incorrect.
              For SSL to work, the certificate needs to have a subject of server.xxxxxxx.local, but the subject t
             hat was found is Consider correcting service discovery, or installing a correct SS
             L certificate.

Not sure if this is my problem?

Any ideas/help would be appreciated!

So out of office messages from your exchange clients are not going to external servers??

In outlook 2007+  they split out of office messages into 2 sections internal and external.  You must set external out of office messages separately from the internal ones.  There are two tabs the internal one is showed first and you must specifically click on the external one.  The messages can be completely different internal and external so be sure to type in the message exactly as you want it shown for external. I always just copy the internal one because i usually want them to be the same.

Yes, I have both internal and external messages enabled via owa.

You need to correct your URLs first.
If you have a trusted certificate on the server then you need to use the external host names internally.

The next thing you should check is whether the OOTO message is being generated and then blocked. That isn't unusual. Use Message Tracking to see whether Exchange is sending the message out. If internal OOTO messages are working, then so should external.

Finally you could reset the OOTO message. Alas that also means cleaning all of the rules in the mailbox out.

outlook.exe /cleanrules

If you have legacy clients, legacy Blackberry BES clients etc then they can create an OOTO message which doesn't always work correctly with the modern dual message method of Exchange 2010.

How can I confirm that the URLs are correct? Also, should both internal url and external be the same?
Simon Butler (Sembee)ConsultantCommented:
In most cases the internal and external URLs are the same. Use a split DNS system to ensure they resolve correctly. As for checking they are correct, that is something that only you will know about from a host names point of view. The web page I have linked to above provides instructions on what needs to be set where for most installations.

Still not resolved

What do you mean by a split DNS system?
Simon Butler (Sembee)ConsultantCommented:
Split DNS - that is when the external name is used internally.

David BarmanAuthor Commented:
Dns seems fine. What else should I be looking at as a source of the problem?
Simon Butler (Sembee)ConsultantCommented:
To be clear - you are able to set the OOTO message?
Outlook behaves as if it has been set with the banner in Outlook 2010 telling you it has been set?

When you send an email, does the OOTO message appear in Message Tracking?

The main reason for external OOTO is a stuck rule, as I have outlined above, or something else blocking the message, like AV or antispam. If that was the case then it would show in message tracking.

David BarmanAuthor Commented:
Problem solved.  It actually wasn't an issue with exchange.  The issue was the smtp email relay service I was using to send out email.  The relay service was blocking all messages with "blank senders".  Once I enabled that feature on their service, the out of office now works.
