When you want you use Forefront Threat Management Gateway to publish Exchange 2010 you must do the following things

1. Get a SAN Certificate.

I my case I have the following URL’s registered with the certificate.
webmail.wardvissers.nl
autodiscover.wardvissers.nl
legacy.wardvissers.nl
casarray.wardvissers.local

2. Import the Certificate in to Exchange 2010.
How to check HERE

3. Create on the Exchange 2010 Server a Client Access Array.
How you must do it I spoke it Configuring Client Access Array. I this case a used casarray.wardvissers.local for the client acces array.

4. Setting the internal & external url’s

Set-ClientAccessServer -Identity ward-ex01 -AutoDiscoverServiceInternalUri https://casarray.wardvissers.local/Autodiscover/Autodiscover.xml

Set-WebServicesVirtualDirectory -Identity “ward-ex01\EWS (Default Web Site)” -InternalUrl https://casarray.wardvissers.local/ews/exchange.asmx -ExternalUrl https:// webmail.wardvissers.nl/ews/exchange.asmx

Set-OABVirtualDirectory -Identity “ward-ex01\oab (Default Web Site)” -InternalUrl http:// casarray.wardvissers.local/oab -ExternalUrl https://webmail.wardvissers.nl/oab

Enable-OutlookAnywhere -Server ward-ex01 -ExternalHostname “webmail.wardvissers.nl” -ClientAuthenticationMethod “Basic”-SSLOffloading:$False

Set-ActiveSyncVirtualDirectory -Identity “ward-ex01\Microsoft-Server-ActiveSync (Default Web Site)” -InternalURL https://casarry.wardvissers.local/Microsoft-Server-Activesync
-ExternalURL https://webmail.wardvissers.nl/Microsoft-Server-Activesync

Set-ECPVirtualDirectory –Identity ward-ex01\ECP (default web site) -InternalURL https://casarry.wardvissers.local/ECP -ExternalURL https://webmail.wardvissers.nl/ECP

5. Configure Exchange 2010 for basic authentication

Set-OwaVirtualDirectory -id ward-ex01\* -BasicAuthentication $true -WindowsAuthentication $true -FormsAuthentication $false

set-WebServicesVirtualDirectory -Identity “ward-ex01\EWS (Default Web Site)” -WindowsAuthentication $true -BasicAuthentication $true

set-EcpVirtualdirectory –Identity ward-ex01\ECP (default web site) -BasicAuthentication $true -WindowsAuthentication $true -FormsAuthentication $false
