we have issue with Dynamic CRM, as it failed to send emails from the application server, however we have check port 443 (since CRM uses EWS for sending emails) its fine, as well as the user is application impersonate, server IP are also added in the relay list.

below is the error once try to send email

Error : system.Net.WebException: Unable to connect to the remote server --->

System.Net.Sockets.socketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.X.X.X: 443
