When creating connections to an Exchange mailbox we need to know the version of the source Exchange environment. Add reference for System.Configuration (to support application configuration).Install Exchange Web Services (EWS) Managed API from NuGet Package Manager.Open Visual Studio and create a new Console Application.Let’s look at the solution in a little more detail. Net, using C# as the language of preference, hooking into the Exchange Web Services (EWS) Managed API as the polling endpoint and using simple SMTP endpoints to send mails. Transform the received email to an SMTP-friendly message to be sent to a list.Use an efficient calling mechanism to poll for new email based on a given criteria.Listed below are the steps, I intended to follow: In my scenario there was a requirement to develop a program to retrieve mails from an Exchange mailbox and, based on a specific criteria, send the email to multiple users based on an distribution list identifier. In this blog I’m going to take a look at one way we can do this. The component reading the emails can read the mail content, parse its contents and transmit the data to other downstream systems.
