Multiple exchange 2010 servers in a single domain?
Posted on 2013-01-22
We currently have 1 single domain abc.com and 1 single exchange server 2010 standard. We are investigating the possibility of adding a second exchange server. The new server would have the mailboxes for the new "branch/division" office. Our current setup is abc.com. We would like to add abcd.com and have all mail for abcd.com go to the new server. We would like to separate the mailboxes to the new server. We don't really want to add the new mailboxes to the existing server setup.
My questions are:
1. Is this a possible/feasible setup? We don't want to use the existing server to hold the new branch office mailboxes.
2. Will the GAL show both users on each exchange server? We would like one list. We won't be using public folders or any real shared resources between the two servers other than the GAL.
3. Any other possible ideas to achieve the same solution? A new server with all mailboxes on one server?
4. Scalability? Our current server has 100 mailboxes on it. The new server would be an additional 150 mailboxes. 250 for a new server will all mailboxes on one server.
