Resolution
  • Exchange send connectors use port 25 by default
  • There is no way to change this in the GUI
  • In order to change the port, run the following PowerShell commands as administrator:
    1. Get a list of your send connectors:
      • Get-SendConnector | select name,port
    2. Change the send connector port:
      • Set-SendConnector “MySendConnector” -Port 587
        • NOTE: replace ‘MySendConnector’ with the name of the appropriate send connector
    3. Verify that the port has changed
      • Get-SendConnector “MySendConnector” | select name,port
