  • Exchange 2010 OWA issue

    Hi Guys

    Just need some help with Exchange OWA

    In a ESXI setup i have

    1) One Domain Controller
    1) Exchange 2010 server

    When i created the domain i created it as domain.local rather then my domain name domain.org

    Configured the Exchange initial configuration and everything seems to be working fine as in i can receive & send emails externally & internally but have problem with OWA

    When i open EMC and look in OWA settings i have internal link - https://servername.local/owa
    external link - https://domain.org/owa

    from the exchange server itself or domain computers i can type in the Internal OWA link in IE and it opens OWA fine but if i type in the Internal or external link of the OWA from non domain computers i get a page cant be displayed Error message

    in my DNS record -

    I have an A record created automatically - server.local pointing to its internal ip address
    i have also added a DNS entry with my public ip address as a host record

    i have a DNS package from my ISP where i have mentioned all domain query to be forward to my public ip address

    but still no luck

    I have also done a Port forward to of port 80,443 & 25 from my modem to my internal exchange server ip address

    Are the non-domain computers inside the LAN?

    If so you will need to create an (internal) DNS zone for domain.org with records for the public names.

    split dns for more info

            URL Redirection? Nothing like that needs to be setup in Exchange.

            Browse to the root of the site - so if you were tyring to use https://host.example.com/owa then browse to https://host.example.com/
            You should see the IIS logo. If you don't then either
            a. You haven't got your DNS setup correctly.
            b. You haven't got the port open on the firewall.

            Unless you have changed the self signed SSL certificate for a commercial one you would probably also get an SSL warning prompt when you attempt to browse to the site, that can be bypassed for the purposes of testing.

              Hi Simon

              thanks for the info

              if i try https:/host.example.org then i still get a IE unable to open page.

              1) Do i need to open the ports in the Windows firewall?
              2) in my DNS settings in AD server, all my records rear as server.local so how do i create a server.org record? unless i create a split dns with server.org?

                You need to forward at least port 443 from your public IP through the firewall to the CAS role
                If SMTP works inbound, you follow exactly the same procedure

                If all your non-domain clients are outside the LAN you do not need to create split DNS

                  in my adsl router i had port 80,25 & 443 forwarded to my internal ip add of my mail server. but i haven't opened port in the windows firewall for inbound connection to any of those port.

                  in the past when i created AD i created as domain.org so all my dns record and server record was reading as server.domain.org so it was easy, and didnt need to open any port from windows firewall although i needed to forward the ports from my modem to my internal server add.

                  At my work we have domain.local setup so as a test i scraped my old setup at home and wanted to try domain.local , everything i could get to work but the OWA ..

                  anyway i have now taken the domain.local off and reinstalling everything as domain.org

                    Re: Exchange 2010 OWA issue

                    Reinstalled ESXi 5 again
                    Will be installing AD & Exchange again today..

                    I will try the .local again but just need to clarify couple of things

                    1) After i install the domain.local AD i will install DHCP role
                    2) then i will install exch server and add the server to domain & install exc 10
                    3) initial config of exch as in send & receive connector

                    4) Already have ports forwarded from my ADSL

                    5) what do i need to do in my DNS to make sure that OWA link works? other then creating A & MX record?

                    6) Do i need to open those 443,80 ports in windows firewall?

                    if anyone wants to help ??

                      you dont need to open ports on the server, they'll be opened automatically when the service is running.

                      you need to open port 80 and 443 on the router, and ensure they are pushing traffic to the server/

                        as you can see from the attachment

                        My DNS (internal) has an A & MX record created with the Internal IP
                        DNS (External) shows that forward mail.misfer.org to my public IP
                        there is a cname created that tells that mail.misfer.org = my internal mailserver name (w2k8exc10.misfer.local)

                        still the same issure cant access to my external owa link from outside the lan
                        https://mail.misfer.org/owa
                        cant go upto https://mail.misfer.org , dont even get the IIS logo.

                          Re: Exchange 2010 OWA issue

                          Should i be creating another forward lookup zone in my DNS management and name that zone "Domain.Org"?

                          then create A record with the internal Server ip address?

                            You don't have to create a complete zone for the domain.
                            Just create a zone for owa.example.com and then create an A record in there with a blank host name. That is single name split DNS. Makes it a lot easier to manage than trying to replace your entire zone internally.
