  • Advanced Exchange 2003/2007 RPC proxy problem. Moving mailboxes for remote access use

    Advanced Exchange 2003/2007 RPC proxy problem. Moving mailboxes for remote access users.

    Im not sure if this is an Exchange specific question, or an IIS specific question so Ill start in the Exchange section.

    *I am planning an upgrade to Exchange 2007
    *I have set up a test environment in vmware to simulate this process.
    *I have an Exchange 2003 server that is configured to use RPC over HTTPS. There are approximately 150 users across the state that use Outlook over HTTPS and having help desk guys call them to reconfigure their profiles would be pretty unsatisfactory.

    *There is just a single 2003 server. (exch01)
    *Planning on moving to a single 2007 server. (exch02)

    When a mailbox gets moved from one server to another and you open outlook for the first time after the move, it updates your profile with the new server name. There is a technical name for this, but I dont recall what it is.

    I have configured Outlook Anywhere on EXCH02 and the RPC Proxy is installed

    Now on to the hard part. How to manage those remote users.

    I moved a test mailbox, tried to reconnect with an outlook/https client and (not to my surprise) it would not connect to my mailbox, but it DID update the profile. If I go into settings I can see that the profile is pointing to the server that the mailbox was moved to. This is good news!

    The next logical step in MY mind is how to get the RPC server to allow traffic to be forwarded to the other system (exch02)

    Am I on the right track? Or do I need to go about this a different way, and put in a 2003 front end server and switch the current server to back end, install the rpc proxy on the front end yadda yadda lets hear it!

    If you want to have any kind of co-existence period you are going to need a third machine. It will have to be an Exchange 2007 server with the CAS role. Move the SSL and DNS entry to that machine and then point the port 443 to that machine.

    Once all clients have connected and been updated, and you have removed the Exchange 2003 server then you can remove the CAS server and put the DNS and certificate on to the single server.

    Simon.

      Thanks for the comment. I have previously found your website a pretty useful place to visit.


      The CAS role server makes sense. I'll give it a shot!
