Exchange 2016 architecture ( https://technet.microsoft.com/en-us/library/jj150491(v=exchg.160).aspx)
- Exchange has to be installed withen the internal domain network with Active Directory (AD).
- We need 3 servers totally:
- Server1: Domain controller, install AD DC, and DNS roles
- Server2: Exchange server; To install exchange server, Server2 needs to join the domain first.
- Server3: This server is gonna be in Perimeter network (DMA zone), meaning dont join it into the domain.
- Server1: The DNS server setup.
- The Forwarders setup to the ISP's dns so that any queries the local DNS can not resolve will be forward to the ISP's DNS servers
- Setup Server1,2,3 with static internal IPs and the DNS pointing to Server1's IP addr as the local DNS server is installed on Server1.
- Server2 - Exchange
- Join the domain then install Exchange server
- Server3 - the server in DMA
- Make sure this sure does not join the domain. Install Edge Transport server here
Setup Edge Transport Server:
- In the Server1's DNS server, add Server3 and it's ip address so that Server2 and Server3 can see each other.
- On Server3 (Edge Transport),
- Open "Exchange Management Shell"
- Run command to create xml
- New-EdgeSubscription -filename c:\edgeSubscription.xml
- Select Y then copy the xml file to Server2
- On Server2 Exchange server,
- Run command to import xml
New-EdgeSubscription -FileData ([byte]$(Get-Content -Path "C:\edgeSubscription.xml" -Encoding Byte -ReadCount 0)) -Site "Default-First-Site-Name"
If not sure what is the site name, run "disite.msc" to found out.
Run command to confirm import successful, it should show "SyncStatus: Normal"
If the SyncStatus is not Normal, or can not ping Server2, it could be the firewall blocked the inquery. Turn off the firewall.
Setup the router:
Go to Port Forwarding setup:
- Ms Remote desktop: TCP port 3389 to Server1 Domain controller port 3389
- Smtp-edge: TCP port 25 to Server3 port 25
