  • Internal address issues when I bring up the old exchange server

    Hi, I migrated from Exchange 2003 on SBS2003 to a 2010 hosted solution. The SBS is still running with the exchange services set to manual.

    I need to run the exchange services again to do some more exporting of messages. However, when I run the old exchange server, it has an impact on my users ability to send to internal users.

    It seems to me that when a user types the address of another internal user, Active directory recognizes it as an internal address on the old server and changes the smtp address and and delivery is attempted to the old server resulting in an NDR.

    Here is an example of what the SMTP address is converted to when the old exchange server is running.

    [email protected] is translated to.....

    IMCEAEX-_O=JWDOMAIN_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=R [email protected]
    #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

    The question is, what can I do to my existing configuration that will allow me to bring up my old Exchange database and not affect the addresses of my internal users when they send email to one another?

      Thanks for the reply,

      Internal domain is JWdomain.local, external is JW-domain.com. Note, internal name does not contain the "-". This is not a typo.
      Thanks,
      Jeff

        First - Exchange doesn't use the SMTP address - however if you are connected to Exchange and enter an SMTP address of a internal user, then Exchange will use it to resolve the user.

        The behaviour you are seeing is what I would expect when you have moved from one Exchange environment to another if:

        1. The users still have Outlook profiles pointing to the old server.
        2. The users have contacts in their address book that are simply users from the old system.
        3. The users have their old nicknames files with the former internal user accounts listed.

        Furthermore, as this is SBS 2003, I suspect that Outlook may well be reconfigured each login by the SBS management tools, and therefore reconnecting to the old server. Of course this connection is only successful when the server is running.

        Trying to stop SBS from doing what it does though is an uphill struggle and you may want to ask in the SBS forum how to stop it from setting up Outlook.

        Simon.

          Thanks Sembee, I think I'm going to be restoring missing email from OST files. I'm trying a tool called "Recovery Tool Box". Seems pretty good.

          I'll be decomissioning the sbs server as soon as I can get the new Std 2008 box configured. I'm using Swing Migration.

          Again, thanks for your help.
