  • Same username in multible domains

    Hi All,

    I wonder if this is possible?

    I have setup an exchange server 2003 for multible domains using the posts in this forum. Luckly i have setup the server on vmware so was able to restore to snap shots when i made a mistake.

    Anyway now to my problem:

    I have two users who are in different domains that have the same name. And they want the same email address for their respected domains.

    ie : [email protected] and [email protected]

    I understand that the username will not have to be the same as the email address but when the users (who do not connect to our domain) login using OWA they will need to use their email address to login with.

    If I give them a different username from their email address it will only cause problems.

    So can this be solved?

    Btw each domain has a different mail store if that helps.

    I'm not sure I understand your question. Can you please simplify it?

      The email address has nothing to do with the user name.
      Therefore give each user a unique username

      so john.smith and jsmith and then give them the email address they want and set it as the default.

        I undestand that the username can be unique, but when they logon to OWA I want them to use their email address not username. Will the server use their email address to logon?

        Secondly how can I use the email address to authicate when setup of their email on Outlook instead of "servername/username" when using RPC over http.

          Hi,
          As I understood.

          You have configured one Domain Controller with test.com and created recipient policy with testdomain.com and otherdomain.com

          So now you need to create each unique user with mail ID of @test.com and after that replicate recipient policy and set it to default.

          eg:
          smtp: [email protected]
          SMTP: [email protected]

          smtp: [email protected]
          SMTP: [email protected]

          Now you can able to login in OWA with test\john.smith and test\jsmith

          Please reply on this that I am going right way for your query or not.

            You are right in saying that i have one Domain controler. But I am hosting two email domains. The users are not on my domain and use OWA to get their mail.

            They use their email address to logon to OWA. Now first problem I have is I have two John Smiths who are on different domains but want to have a email called [email protected] and [email protected] respectivily. Although I have not set them up yet i am sure they will work using their email address to logon to OWA.

            The problem I also have is I am about to roll out RPC over Http and still want them to use their email address to authicate on their outlook instead of using "domain/username"

            Question: can I use email address in outlook to authicate or will i have to use "domain/username". Secondly will it save the password or will I need to put it in each time.

              If the machines are members of the domain then RPC over HTTPS can be set so that authentication prompt is not required. However if the machine is not a member of the domain then you will get prompts. While there are a number of methods to save the password I don't recommend that they are used because it is a security risk.

              As for logging in as the email address, you have to add UPNs to the domain. Google for instructions on that, it is quite straight forward.
