Autodiscover and Email


  • Hi People,

    Hoping some people can advise.

    Rolled out a new servers last weekend.

    We have two servers as example below:

    Mainserver1 - Domain Controller  -
    Mainserver2 - Exchange 2013 -

    Using exchange connectivity test, autodiscover fails to find domain or anything. Nothing is successful.

    If i ping this address though it resolves to the correct IP address of the firewall.

    The firewall has HTTP and HTTPS being forward to the Domain controller

    I am not an expert with DNS or IIS but I am thinking that I need to do one of the following:

    1. Go into the firewall and allow traffic for HTTP and HTTPS to in addition to


    2. Add a DNS entry to pointing autodiscover towards

    On top of this, I am not sure if I need to do anything in IIS so not entirely sure what the best method is to get this resolved. 

    Grateful if anyone has the time to help me get it resolved as I am sure its pretty straight forward.

  • Create SRV record in dns.


    Service : _Autodiscover

    Protocol : tcp

    priority:  0

    weight:  0

    Port Nmber: 443

    Host offering this service :

  • Thanks Lubra_ali786,

    My internal outlook clients are also having trouble connecting.

    Before I go ahead and confirm this record change could I just confirm the following:

    Running Get-ClientAccessServer | FL AutoDiscoverServiceInternalUri  from Exchange shell returns:

    Do I need to make the 'Host offering this'????

    Essentially I want clients to connect externally via web app
    Configure my internal cert and autodiscover to match so they work.

    Does that sound right?

  • I was check in my test lab , that is perfect working in internally. Put Host offering this service :

    and also HTTP redirect Autodiscover in the IIS to OWA URL . Here is the example.

  • Still no luck with this.

    This is the scenario in more detail and I would appreciate any help someone can give to help resolve.
    Far to much time wasted:

    Server1 – Domain Controller
    Server2 – Exchange Server

    Exchange 2013 server setup fresh but clients internally cannot connect to the server using Outlook. So far I can confirm the following:

    I created a self signed cert with loads of entries including:

    On running :
    Get-ClientAccessServer :: FL AutoDiscoverServiceInternalUri
    the following is returned:


    If I ping the IP address is correctly resolved so I can get to the firewall.

    The firewall has a rule that allows HTTP and HTTPS to the domain controller.

    The domain controller has a SRV record within which reads:
    Host: autodiscover.mylocaldomain.local

    What am i missing??? Anyone know?

  • Hi,

    Input the in IE and see whether code 600 is returned. If so, it means autodiscover works fine.

  • Hi Simon, 

    I just tried and it does not return anything.

    Does external autodiscover need to work for internal clients to work?

    There are two parts to this...

    1. Get internal clients working

    2. Get external working

  • Move HTTP(S) to Exchange server not DC.  Exch is offering these services not the DC.
