  • Multiple sites, one company domain. How?

    Hi all,
    Just wondering where to start with this. Currently POP3 connectors are being used at 2 sites, both with SBS 2003 to deliver email to two sets of users but both with @ourcompany.com domain names. We want to move to a W2K8 solution with Exchange 2007 and as a proper email server instead of POP3 download (which you can't do in Exchange 07, by default, anyway). I have set up a standard Exchange 2007 installation before elsewhere but not sure where to start with two sites, connected only via ADSL connections (512kbps DL, 256kbps UP, max) to the internet).
    We will be creating the solution from scratch, inc hardware, likely.
    Any ideas?
    Thanks!

    You need to speak to a consultant who can assist with the design of the site.
    If I was doing it, I would be looking at two days work to do a correct design for the installation and the migration path - and with all due respect I am not giving away UKú1500 (US$3000) of consultancy for free.

    Things you have to consider...

    Hardware (well documented on Technet)
    Domain design, including sites and services in AD
    SSL certificates
    Client Access Point of Entry (unique or both sites).
    Message Flow (do the servers deliver email directly themselves, or through one site - both inbound AND outbound).
    Are you going to merge the regular data, replication, file and folder structure, login scripts etc (basically everything that goes in to a domain).

    Then you have to consider the migration path, one domain has to go, does the other domain go as well and how you migrate the data in to the domain.

    There is a lot to it, and it would take me some time to type it all up.
    If you want it done correctly and you want the deployment to go to plan and last you for some time to come, then you need to get external advice. Multiple server deployments and merge of two domains makes things a lot more complicated.

      Don't need any external consultants thank you very much. I have done complicated 2K3 AD migrations to 2K8 already, and Exchange 2003 -> 2007, and got past all the nightmares along the way. I can do details, just after a conecept of how it might be done, in general over slow ADSL links. RODC? VPN?

        In a nutshell, Outlook Anywhere (RPC/HTTPS)
        Users at the home site will connect over TCP/IP
        Users at the remote site will connect over HTTPS and cache emails locally

          I tend to agree with Sembee, without more info it is hard not to just give general advice.

          How many users for example?
          From the basic info you have posted I could say just create the user accounts manually (import-csv maybe). Exmerge the mailboxes out and exmerge in.
          If you need to keep the 2 domains running you can provide OWA access in the mean time and exmerge depending on date.
          cheers

            Thanks guys.
            Ossian, good idea, just worried about how slow the ADSL links are. Also, never had much luck getting ISA 06 working with RPC over HTTPS. There are 5 users at two sites which are both very rural. What about putting the exchange box in a datacenter? Is that an option if the domain controller is on-site with only a 256k uplink?

              5 users in two sites I wouldn't even be considering a server in the second location.
              Either a single server or a data centre. Single SBS, nothing more. Anything else is overkill I would struggle to justify the costs involved.

              Heck, I would probably be encouraging them to outsource to a hosted Exchange environment, with a file server in a data centre.
