I have a Microsoft Exchange 2010 installation. I purchased a UCC certificate, but I am having issues because of the changes in UCC SAN issuance related to invalid FQDN.
Now, I'm trying to fix a problem where all of my clients are getting certificate errors internally because the internal FQDN is xxxx.xxxx.LAN. Obviously the UCC points to the outside FQDN. Since I cannot add anything to the certificate to aleviate this, I'm trying to get the server to return the external FQDN whether accessed from inside or out.
Currently, it returns the internal FQDN whether accessing it from inside or out. I have executed the following Powershell commands in an attempt to fix this, but to no avail:
Set-ClientAccessServer -Identity MYLOCALSERVER -AutodiscoverServiceInternalUri https://MYEXTERNALSERVER.MYDOMAIN.com/autodiscover/autodiscover.xml
Set-WebServicesVirtualDirectory -Identity "MYLOCALSERVER\EWS (Default Web Site)" -InternalUrl https://MYEXTERNALSERVER.MYDOMAIN.com/ews/exchange.asmx
Set-OABVirtualDirectory -Identity "MYLOCALSERVER\oab (Default Web Site)" -InternalUrl https://MYEXTERNALSERVER.MYDOMAIN.com/oab
