Need some clarification on setting up Exchange 2007 using mulitple certs. Currently I as setup a second IIS site for OWA with a 3rd part Cert using webmail.domain.com. We want to use Outlook Anywhere and I understand that we need to enable autodiscover on the external. So I plan to either create a new host record and point it to another public IP and create another IIS site (giveing a total of 3, default, webmail, and autodiscover) or using the new patch available and setting up a SRV record for autodiscover. I know that when adding autodiscover to another site I need to remove the autodiscover virtual directory from the default site and change my SCP. What do I need to do with OAB and EWS directory, I plan on pointing the RPC/HTTPS at the webmail.domain.com URL. Can I create another copy of these directories without hurting anything or will leaving them on the default website still allow them to be accessable form RPC/HTTPS. If some could clarify this for me, as I haven't found much documentation on the OAB and the EWS directories when using mulitple SSL certs. Thanks in advanced, Jeremy
