We are deploying an Exchange 2016 server in one Forest & one domain name but in multiple sites.
On Exchange 2016 ( Main site)
2nd Exchange ( 2nd site )
( these two server will be in DAG )
but 5 other site will have separate Exchange server 2016 but will be same domain. but i want to know the mail flow between these site. only the member of that site will have there mailbox in there server only. all site will have there different IP schemes.
Any advice to make there exchange environment error free. waiting for you reply.
