There are no pre-defined solutions for this problem since this can be different from client to client. Bellow you have 2 approaches:

1 - verify proxy configuration
  1. Open the internet options as the service account
  2. Go to the connection tab and click the Lan settings
  3. validate that the proxy settings are set to accept the connections to the Exchange environment
2 - Firewall configuration
  1. Access the firewall configuration and verify if the connectivity to the Exchange cluster from the RightsWATCH cluster is opened on port 443 (the default EWS port)
