Send Email using Outlook Exchange Web Service (EWS) - C# Console Application Example

In this blog, I am explaining how to send mail on any domain using an exchange server. You can implement an exchange server following this step.

Step 1 - Create a Console application.

Step 2 - Add "Microsoft.Exchange" library reference in your console application.

Reference -> Manage Nuget Package--> Add below package

Microsoft.Exchange.WebServices

Description:

The Exchange Web Services (EWS) Managed API provides a .NET Framework interface to EWS in Exchange Online, Exchange Online as part of Office 365, and versions of Exchange starting with Exchange Server 2007 Service Pack 1 (SP1). 

You can use this version of the EWS Managed API to evaluate the library for your application needs, to compare it to directly using XML or the auto-generated proxy library, and to create production-ready applications.

or Add via PowerShell commad

PM>Install-Package Microsoft.Exchange.WebServices

Step 3: add "System.Configuration" library in your console app

Thereafter create a method to create mailing concept using exchange server.

using System;

using System.Configuration;

using System.Net;

using Microsoft.Exchange.WebServices.Data;

namespace SendmailByEWS

{

    class Program

    {

        static void Main(string[] args)

        {

            string MailUser =ConfigurationManager.AppSettings["MailUser"];

            string MailPass = ConfigurationManager.AppSettings["mailPass"].ToString();

            string MailTo = ConfigurationManager.AppSettings["MailTo"].ToString();

            var isSentEmail = SendMail(MailUser, MailPass, MailTo);

        }

        public static bool SendMail(string MailUser,string MailPass,string MailTo)

        {

            try

            {

                ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);

                service.Credentials = new NetworkCredential(MailUser, MailPass);

                service.AutodiscoverUrl(MailUser, (a) =>

                {

                    return true;

                });

               // service.AutodiscoverUrl(MailUser);

                EmailMessage emailMessage = new EmailMessage(service);

                emailMessage.Subject ="Profanity Alert! | Profanity Found | Review";

                emailMessage.Body = new MessageBody("Hi Admin, profanity found, please review and take further action");

                emailMessage.ToRecipients.Add(MailTo);

                emailMessage.SendAndSaveCopy();

                return true;

            }

            catch (Exception ex)

            {

                return false;

            }

        }

    }

}

Dont forget to Configuration values in App.config file

<configuration>

  <appSettings>
    <add key="MailUser" value="girishkumar.s@{Tenant}.onmicrosoft.com"/>
    <add key="mailPass" value="********"/>
    <add key="MailTo" value="abc@{Tenant}.onmicrosoft.com"/>

  </appSettings>

    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>

</configuration>

Put Tenant name
