How to Send Email Messages using Exchange Server & Exchange Web Services

This technical tip explains how to send email messages using exchange server & exchange web services inside .NET applications. You can send email messages using Exchange Server with the help of the tools in the Aspose.Email.Exchange. The ExchangeClient.Send() method accepts a MailMessage instance as a parameter and sends the email. Please follow the following steps to send emails using Exchange Server:

• Create an instance of the ExchangeClient class.
• Specify server name, username, password and domain.
• Create an instance of the MailMessage class.
• Specify the from, to, subject and other MailMessage properties.
• Call the ExchangeClient.Send() method to send the email.

The sample code below sends email messages using Exchange Server.
[C# Code Sample]

// Create instance of ExchangeClient class by giving credentials
ExchangeClient client = new ExchangeClient("http://MachineName/exchange/username",
    "username", "password", "domain");

// Create instance of type MailMessage
MailMessage msg = new MailMessage();
msg.From = "sender@domain.com";
msg.To = "recipient@ domain.com ";
msg.Subject = "Sending message from exchange server";
msg.HtmlBody = "<h3>sending message from exchange server</h3>";

// Send the message
client.Send(msg);

‘Create instance of ExchangeClient class by giving credentials
Dim client As ExchangeClient = New ExchangeClient("http://MachineName/exchange/username", "username", "password", "domain")
