Hello Everyone,
I just install a fresh copy of Microsoft Exchange 2016 cu14 (on premises) which is the latest from Microsoft.
I have configured DNS
I have applied product key to both Mailbox Server and Edge Transport Server.
I have bought and applied UCC SSL certificate to Mailbox server.
I have opened all ports as listed on Microsoft website for Exchange Server communication.
I can send emails with/without attachment to the internet.
The problem is messages from the internet get stuck in the queue on the Edge Transport Server.
Could anybody help me with any other configuration I need to do?
Thank You All.
