Two exchange servers on one domain

Question

Good afternoon,

I have searched for an answer to my question and its either not possible or I am not searching for the right information so here goes.

I have a single domain contoso.com

I have two exchange servers in the same domain.

Is there a way to have both exchange servers synchronize user mailboxes and based on site/subnet service the users mail requests?

Ideally, I would like to not move user's mailboxes based on the site/subnet they are associated to for a specific exchange server. but have the exchange servers sync user's mailboxes as if they were both one mail server.

If this is not possible then I will perform the necessary mailbox move for the users.

Thank You in advance.
Mr. Mac.

Answer 1

Hi there, syncing mailboxes between servers is not possible, not. the mailbox can only exist in one database at any one time , mounted on one server.

You can sync databases however using database availability groups, but that isnt the same thing of course.
