we currently have two exchange 2013 servers running on 2008r2 at our main office. they are in a DAG, everything replicating correctly.
we are going to add a 3rd (virtual) 2013 exchange server at a remote site in the near future. that site is being setup for DR, we have a 50 MB connection to the site.
I have been doing some research today on site resiliency, but I have not seen any examples where you had only 3 exchange servers.
can I do site resiliency with only 3 servers?
will I have to have a 3rd site for witness server?
all we are trying to do, is to set it up so that if site 1 with the two exchange servers go down for some reason, site 2 with the single exchange server will then be available to keep email flowing throughout the company.
