It really just means that all of your virtual directories have that name assigned to them for the ExternalURL. And you don't need to change this for TMG. You just need to load the certificate onto TMG and have it forward the data as SSL.
That is dependent on the security needs of the client. From: [email protected] [mailto:[email protected]] On Behalf Of Geoff Orlebeck Sent: Thursday, March 6, 2014 5:28 PM To: [email protected] Subject: [Exchange] Exchange 2010 CAS Modification If you all recall, I had an issue months ago with Exchange Management Console not working and so we ended up reimaging the server and installing AD/Exchange fresh. For my part, I was tasked with installing Exchange 2010 for the customer. I performed the install unaware they are going to add Exchange TMG server to the mix. During install I selected the CAS would be Internet facing and supplied "mail.domain.org" as the external domain name. My understanding is if a TMG is in the mix, you would not select the CAS as Internet facing. I checked Technet and around MS blogs but don't see anything about "disabling" this portion of the server. I'm not sure what properties I need to remove, or do I actually need to rerun the installation in some fashion (or the worst case, start from scratch). With how flexible Exchange is, I figure there's somewhere to remove that "Internet facing = true" scenario, just not sure where to look. I'm fine with reading if someone has any helpful links, but my searches mostly yielded disabling redirection in multi-CAS environments. Not what I'm facing. Thank you!
