I'm sure there is a simple solution but this has me stumped. I want to setup email notifications but the test message keeps failing. The error is not helpful as it simply states "error occurred while sending the test message" with no elaboration when you click on "details". There is a code of 13,107,201(0xC80001) if that helps.
I am able to send the email using telnet from the same machine and the same credentials so I am happy that I can see the exchange server and that it is not rejecting the message in anyway.
