Hello, I just need verification & guidance on my Outlook Anywhere & External Autodiscover access (via DNS) implementation plan. Kindly help with questions I would be most Grateful. Thanks, Abhishek

Unless you have clients on your network that are NOT part of the domain, then you do not need to have internal autodiscover entries. With regards to autodiscover, that only needs to be enabled on the internet facing CAS servers. You should have an SSL certificate of some description on all CAS servers.

I believe I have answered your questions. Is there something that isn't clear about what I have written? The external URL needs to match whatever is on the SSL certificate and resolves to the correct place. Posting the same question again doesn't help - I have reported the duplicated post for removal.
