MailMessage msg = new MailMessage();
msg.To.Add(new MailAddress("someone@somedomain.com", "SomeOne"));
msg.From = new MailAddress("you@yourdomain.com", "You");
msg.Subject = "This is a Test Mail";
msg.Body = "This is a test message using Exchange OnLine";
msg.IsBodyHtml = true;

SmtpClient client = new SmtpClient();
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("your user name", "your password");
client.Port = 587; // You can use Port 25 if 587 is blocked (mine is!)
client.Host = "smtp.office365.com";
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = true;
try
{
client.Send(msg);
lblText.Text = "Message Sent Succesfully";
}
catch (Exception ex)
{
lblText.Text = ex.ToString();
}

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();

//Read fromEmail from registery
string fromEmail = Registery.fromAddress;

//Read fromPassword from registery
string fromPassword = Registery.password;

//Read toAddress from registery
string toAddress = Registery.ToAddress;

//Read outgoing server name from registery
string smtpServer = Registery.smtpServer;

//Read port of outgoing server from registery
int port = Convert.ToInt32(Registery.port);

//Read whether enableSSL is true or false from registery
bool enableSSL = Convert.ToBoolean(Registery.enableSSL);

message.From = new MailAddress(fromEmail.ToString());
message.To.Add(toAddress.ToString());
message.Subject = ServiceName + " " + status.ToString();
message.Body = "Service Name :" + ServiceName + Environment.NewLine + "Status :" + status.ToString();
message.IsBodyHtml = true;
message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;

///smtp server and port configured at registry
SmtpClient smtpClient = new SmtpClient(smtpServer, port);

///enable ssl is required for secure connection.It is must be true for gmail server and false for other servers.
smtpClient.EnableSsl = enableSSL;

smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new NetworkCredential(fromEmail,fromPassword);
smtpClient.Send(message);
}

catch (Exception ex)
{

Logger.Log("Error In Sending Mail. " + ex.Message + " , " + ex.InnerException, 3);
}
