Question
Outlook Anywhere from outside does not work
Experts,
I am trying to troubleshoot my Outlook Anywhere from outside my network. When I try to use the Autodiscover by entering in my name, e-mail address and password, I get prompted for a username & password. After entering the credentials I get a pop-up saying "The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
When I enter in settings manually - I get the same message.
Internally, everything works ok including Autodiscover.
It is a single Exchange server and I have ports 80 and 443 forward to it. OWA works fine from outside.
When I run an Outlook Anywhere test from https://www.testexchangeco
Everything passes except the last step -
Testing Http Authentication Methods for URL https://email.domain.com/r
Http Authentication Test failed
Additional Details
A Web Exception occurred because an HTTP 404 - NotFound response was received from IIS7
