Deploying second Exchange 2010 server, to move mailboxes to remote site

Posted on 2011-10-25

Hello all,

I have a Exchange 2010 server in the main office, with about 70 mailboxes on it.  All roles are running on this server directly, and everything is functioning as it should.

I have a remote office with about 20 users, and due to some bandwidth and size/space issues, would like to move their mailboxes to a locally-installed second Exchange 2010 server.

The sites are connected via an MPLS VPN, which in essence makes them on the same network.

In the AD Sites and Services, they are broken up into two sites.

The main office is 192.168.50.x, and the remote office is 192.168.60.x.  Using a subnet, each office can access each others files, etc.

I would like some insight as to what roles I need to deploy on the server up there.  I am not needing to setup DAG right now.  My main concerns are mail flow, webmail (and by extension, activesync devices).

Do I just install the mailbox role, or do I need to install a few of them?

If I install for example the transport role, will I need a separate webmail link for the remote office?

    you will need to install all 3 roles (CAS/HUB and mailbox) in the other site for this to function correctly

    Hi tnorman,

    For the mailboxes to be local to the site you would have to at least install a mailbox server on the site, but would be a good idea to have the CAS for local authentication and the hub for queuing mails should the lines go down between your site and theirs.

    In short, I would install all roles at the second site, but that is just me. You don't need to Enable outlook anywhere on the newly installed servers, they will still access OWA, autodiscover etc. from your primary site.

    installing only a mailbox is not an option, a mailbox server requires a cas and a hub in its own AD site, the only way is to deploy all roles
