  • 2003 OWA is dead, can i install 2007/2010 FrontEnd using 2003 Exchange mailboxes ?

    Hi guys,

    I have EX2003 and OWA2003 on the DMZ.

    My OWA server just died and i was wondering what are my options ?

    Can i work with EX2003 but OWA 2007/2010 or do i need to migrate me Exchange to 2007/2010 ?

    Thanks !

      Hi!

      Well, i've googled it before asking but there is no step-by-step instructions nor a situation in which i am in.

      All the artciales are based on Mixed 2003/2007 Env. - i'm running pure 2003 env. and just want / need 2010 OWA.

      My question is : is it possible with 2010 or only 2007, and how the HELL do i do it ?

      i'm not planning on moving my EXCHANGE from 2003 to 2007 or 2010.

      if you can just pin-point me to the specific article I will be forever gratefull ...

        well, once you put a 2007 or 2010 server into the environment, it's no longer going to be a native environment is it?

        if you;re not planning on moving towards 2007 or 2010, why wouldn't you just reinstall a 2003 FE server and save yourself the head ache it's causing?

        I'd use the maxim 'if it's not broke, don't fix it' - but it is broke, so let's try this.
        'if it's broke, fix it, don't try and enhance it'

        I haven't been able to find enough information to build a step by step guide on how to do this, but in the past 20 minutes, i've found enough information to give it a go.
        I'd install the CAS server, I'd make the EX03 server a backend server, and i'd make sure that problems identified here (for instance) are taken care of.

          Exchange 2010 isn't going to be suitable for two reasons.

          1. It isn't supported to put anything but Edge server role in a DMZ
          2. Exchange 2010 doesn't proxy, it only redirects, so you would need to have Exchange 2003 exposed to the Internet, with a unique IP address and host name, which rather defeats the point of having the server in the first place.

          You could use an Exchange 2007 server with the CAS role, but that is subject to the same restriction with regards to the DMZ support - but can proxy Exchange 2003 so only one server is exposed to the Internet.

          Exchange in a DMZ doesn't increase your security in any way, it actually decreases it.

          Personally I would just DR install the Exchange 2003 server that you have lost, put it where it belongs - inside the firewall - and think about the upgrade to Exchange 2007/2010 later. That upgrade is not something that can be done lightly, it is a major change, and should be planned, not done because of an unscheduled event.
