Add Edge Transport Server to existing Exchange 2016 Hybrid

Marcus Wong Theen Nam 1,111 Reputation points

I have an existing Exchange server 2016 hybrid deployment in my infrastructure. Currently all mail between on-prem and O365 routing to my on-premise third party email gateway.

I would like to replace it with Edge transport server so that mail flow between on-prem and O365 can route through the edge transport server.

May I know what's the proper steps to do this? I have the idea below but not sure if this is correct for environment that have an existing hybrid configuration.

  1. Install Edge Transport Server in DMZ
  2. Export the Edge subscription and import it to Exchange on-prem server
  3. Subscribe Edge transport server
  4. Create public DNS record for the Edge server and assign public IP to it
  5. Re-run HCW, select the secure mail flow to go through Edge server and enter the Edge server public FQDN

Is this correct?
