SBS Exchange Autodiscover Cert Replacement

Hi guys....

I have a 2011 Small Business Server.  Everything has been running great for 3 years with a * cert.  Autodiscover, OWA... all of it.  Last month the star cert expired and needed to be replaced.  We didn't want to pay for the star cert again due to cost, so we just bought a standard cert for  

I was able to configure the standard cert and all services work fine using the cert.  EXCEPT... Outlook autodiscover.  When a users tries to open Outlook remotely, they get the cert mismatch error, saying the name of the security certificate is invalid or does not match the name of the target site

I have since purchased another standard cert for  I have installed it on the server and it doesn't show any issues.  If I go into the Exchange Management Console and look at the server configuration I can see the cert and it shows to be valid.  But there does not appear to be a way to assign it to autodiscover.  If I assign the IIS service to it, then the breaks the OWA access and shows it is trying to use the autodiscover cert instead of the remote cert.

So... can this autodiscover cert work?  Or do I have to buy a different cert?  Or have I just not configured the cert correctly for the autodiscovery?  Or maybe any other suggested solutions?

use 1 namespace for all services.
Outlook Anywhere –
Outlook Web App –
Exchange Control Panel –
Exchange ActiveSync –
Exchange Web Services –
Offline Address Book –
AutoDiscover –

you would use instead of mail. A ucc certificate with 5 names for 1 year would have cost you about $300 3 Years less than $250

SBS 2011 with at least Roll Up 4 removes .local from the cert request and handles all the rest "automagically" with a  standard $10 SSL cert.  You need the MX record for the mail, and a A for  Connections for all services should work fine with that if you use the SBS wizards to get from point A to point B.

I am still working on this as I am learning now about these ucc certificates.  Seems the choice to go with from the start.  If I can use but add autodiscover to the same cert it would seem this would work.  Just need to try to get this new cert and see if it will work.
