  • Certificate issue


    The environment: Win 2012 r2 + exchange server 2016 (on same machine since it's small organization)
    The domain name I configured is : company.local
    There is a certificate from godaddy for autodiscover and that installed on the server. Exchange active sync, outlook anywhere works fine and there is no problem.

    My question is regaeding the mapi which configured in virtual direcotories with these url's:

    External URL:
    Internal URL:

    Since i can't add the alternetive name "" to godaddy certificate, the outlook clients which conecct internally get the certificate warning that isn't recognized and if i change the internal URL to "" like the external , the outlook client is disconnected from the server.
    I also noticed that the warning message appears on the stations that include shared mailbox..
    How should i solve this?

    You will probably need to set up "split DNS" so resolves internally to your local IP addresses as well as externally. Then you can change the internal URL to

      Thanks Oossian..
      I created a new zone in DNS called , then created A record with the local server IP.
      I changed the mapi internal URL to, Now the outlook clients connect successfully without the warning message but i can't see in account properties the "connection" tab with the Outlook anywhere and exchange proxy setting. Since it's a laptop, i need to make sure it can connect also from outside the network. why i can't see it?
      Also the server name in outlook account properties: "[email protected]" Is it normal?
