DNS - website now dropped www, so we cannot access the site from inside. RRS feed

  • Question

  • Our third-party web developer just changed the website so it now redirects from www.domain.com to  https:\\domain.com without the www. After this change, no one on the LAN can access our website anymore, because “domain.com” points to an internal IP address. Previously everyone could get to the website because www points to the outside public IP address of our website. Now that the www is dropped that no longer works. We can change DNS to a public site ( and can of course then get website access, but then Outlook disconnects from our on premise Exchange server. Please help. We have numerous portable laptops, so the solution needs to work both inside and outside LAN.

  • You're posting in the wrong place.  You need to post in the voice mail of your third-party web developer.

    What I suspect is happening is that Autodiscover is hitting https://domain.com/Autodiscover/Autodiscover.xml and it's being redirected to the wrong place causing it to error out, since Outlook looks there first (after your on-premises SCP records) even though nobody in the world publishes Autodiscover that way.  But that's just a guess because you didn't really tell us anything.  So you should tell your third-party web developer to ignore /Autodiscover so Outlook times out on it.

    You can start by testing Autodiscover at https://exrca.com.
