Hello,
I am trying to disable Outlook Anywhere Externally. This issue is that we use split-dns and all of our Exchange services point to mail.domain.com both internally and externally. This can't be changed due to our SSL certificate not including the internal server DNS name for the Exchange server, and we still have another two years on it.
Is there a way to white-list a range of IP Addresses (potentially through IIS since Outlook Anywhere uses HTTPS)? Would setting the External URL to null for Outlook Anywhere prohibit autodiscover from configuring the Outlook client, or would it do nothing at all since the internal DNS name is the same as the external?
I could potentially add an internal SSL certificate and change the internal DNS name of Outlook Anywhere. Is this a good move?
Thank you for your time.
