  • Removing Exchange 2010

    I've installed Exchange 2010 on one server with 10 mailboxes, 1 distribution group and done mostly basic configuration limits of Exchange. Later on it was decided to move it to Virtual Machine so I've installed 2nd Exchange 2010 server on that virtual server and both servers are now visible. First server has pop3 connector running that gets emails from external servers. There's no mx running yet as the server was on dynamic IP when setting up started. Now it has static IP so port forwarding will be done to point to the new exchange server.

    I've started Local Move Request for all mailboxes, and it finished successfully.



    What else should I do?
    How I make sure nothing gets lost?
    How do I remove 1st server permanently making sure nothing gets broken?

    Exchange 2010 is much easier than Exchange 2003. Most things are stored in the domain, rather than server level.
    If you use add/remove programs and attempt to remove the product, if there is something stopping it, it will tell you and will not let you remove the product.

    The only way to remove Exchange 2010 is via add/remove programs. No other method is supported.

      Hello Sembee,

      Thank you for your response. Before I do remove one exchange i would like all outlooks to change to new server instead of old one. But currently even thou all mailboxes are moved to new server outlook points to old exchange. Also when old exchange services are down, outlook won't switch to new server .. is it normal and removing exchange will solve it.. or will i just have pain of reconfiguring everything.

        I want to say there's a script or policy you can run that'll fix it for you. Sembee, thoughts?

          Once Outlook has redirected once, that should be it. It shouldn't need to keep doing it.
          Therefore something is changing it. Could be that something is hard coding the server, or "correcting" it via a script of some kind or something.
          Deployment tool, something like that maybe.

          Check public folders have been moved if those are being used.

          What exactly is pointing to the old server?

            Re: Removing Exchange 2010

            So I went thru with uninstallation and it didn't went quite well.. first it complained about couldn't removing mailbox database so I have moved all arbitrary mailboxes to new server (user mailboxes already were moved), then i had to make sure no connectors are set up on that exchange server, and finally when all prerequisites were good to go.. it failed to uninstall Hub Transport Role.

            After some googling i found out you have to uninstall any updates first (Update Rolup 3 or so). It was suggested to install it again first, so I did which it actually installed Rollup 4 so I had to remove both of those before trying to uninstall Exchange. Not sure if reinstalling of updates was needed but didn't wanted to risk it.

            After updates were gone Exchange uninstalled without problems (wow! first installing exchange was hell, now uninstalling didn't go so easy as well).

            So I thought everything is good.. but when i went to new Exchange console there it was .. Some Warning were reported while loading data, and the database that was already removed with old server is still there, just with Unknown status. Trying to remove it brings errors..

            --------------------------------------------------------
            Microsoft Exchange Error
            --------------------------------------------------------
            The mailbox database 'Mailbox Database 0790767150' cannot be deleted.

            Mailbox Database 0790767150
            Failed
            Error:
            This mailbox database contains one or more mailboxes or arbitration mailboxes. To get a list of all mailboxes in this database, run the command Get-Mailbox -Database <Database ID>. To get a list of all arbitration mailboxes in this database, run the command Get-Mailbox -Database <Database ID> -Arbitration. Before you can remove this mailbox database, you must disable, move, or remove user mailboxes and move arbitration mailboxes.

            --------------------------------------------------------
            OK
            --------------------------------------------------------


            Not sure why it complains if it already got everything moved properly to get Exchange to uninstall at all.


            But hrmms, i've decied to point it to Active Directory server directly and then console shows only new Exchange server. When i change it back to default it starts showing old one as well. The fact is the removed exchage was also AD controler but AD (with dcpromo) was removed (more then 2 weeks ago) from it when 2 new AD servers were set up. So there's no longer AD on old server (it's still up and running as it has other services). So not sure where from the info is comming from.


            I must say I'm a bit dissapointed with Exhchange 2010. Feels like it's still a beta, at least when it comes to installation/uninstallation (it's great ppl don't do it daily, otherwise it would be nightmare).

              Exchange doesn't detect another server has gone immediately. Furthermore when Exchange is installed on a domain controller then that affects how all other Exchange servers operate.

              If you restart all of the Exchange services on the existing servers then you should find it will clean itself up.

              I disagree that Exchange 2010 feels like it is a beta - most of the problems you have identified are down to either not following best practises (like putting Exchange on a DC) or just lack of familiarity with the product. If you are used to Exchange 2003 then it is completely different.

              Simon.
