Creating multiple Airlock Gateway mappings for ActiveSync

The next step consists of connecting the previously created virtual host and back-end group with multiple ActiveSync mappings.

    • -Exchange Autodiscover
  5. Go to: Application Firewall >> Reverse Proxy
  6. Connect the new ActiveSync mappings with the corresponding virtual host, which is exchange.ext.virtinc.com.
  7. Connect the new ActiveSync mappings to the corresponding back-end group.
  8. The mappings have been established.
