![]() This is an an e-mail validation system designed to prevent e-mail spam by addressing a common vulnerability, source address spoofing. It’s a good idea if you have a domain – and you have access to your DNS server, that you setup and use (properly) SPF records. You’ll need to enter in an actual mailbox account username and password, but it will fully test your setup and verify that autodiscover is properly setup. Go to the above URL and run the “Outlook Autodiscover” test. If you have your TTL set very high (hours or a day) you may have to wait a day for this to work. These settings have been tested and confirmed, so it does work – but like I said you have to wait for the DNS settings to get updated by whatever DNS server you are using. If you get the dreaded “server name” screen instead, this means your phone is not picking up the most current DNS settings.
