Out of Office Settings Cannot be Displayed SBS 2008

I have two Win7 Pro 64-bit workstations on an SBS 2008 domain.  I am using Exchange for email.  Everything seems to be playing nicely except the Outlook 2007 Out of Office Assistant does not work.  It times out with an error message saying "Your out of office settings cannot be displayed, because the server is currently unavailable.  Try again later."  This happens on both machines, fresh out of the box and with all updates/patches applied.

To resolve the issue I have attempted to follow the workaround shown here: http://www.proexchange.be/blogs/exchange2007/archive/2009/07/14/your-out-of-office-settings-cannot-be-displayed-because-the-server-is-currently-unavailable-try-again-later.aspx.  When running the Test E-mail AutoConfiguration utility, it fails with "Autoconfiguration was unable to determine your settings".

I believe the issue is caused by the Exchange 2007 Autodiscover service not being correctly configured.  The question is, how do I correctly configure Autodiscover to work?  Bearing in mind I am new to Exchange 2007 and Exchange Management Shell.

As far as certificates go, I have a third party SSL certificate that I installed to enable correct functionality of the RWW, OWA and RPC.  Do I need another for Autodiscover?

You should have autodiscover.domain.com also added to the certificate Subject Alternate Names.

Youre certificate should contain following names:
#SubjectName: cn=webmail.xyz.com (example)
#NETBIOS name of Exchange: EXCHANGE2K7 (example)
#Internal FQDN: EXCHANGE2K7.xyz.local (example)
#External FQDN (Public name): webmail.xyz.com (example) (use nslookup/ping to verify the external FQDN)
#Autodiscover name: autodiscover.xyz.com (example)

Hope this helps,

Shree, thanks for replying.

Do I add autodiscover.domain.com to the existing SSL certificate, or do I have to get a new seperate certificate?

Shreedhar EtteCommented:
You need to have all the mentioned names in the single SAN/UCC certificate.

Add it to the existing certificate.

Shree, I have not encountered the term SAN/UCC certificate before.  I am familiar with SSL certificates.  I got in touch with the SSL certificate provider but they have responded that they do not offer alternate names on SSL nor do they have any information about this.  Now I am feeling a bit lost.  Seems Microsoft have made an oversight here.

Contact www.godaddy.com they provide the certificates.

Hope this helps,
