Creating and sending a mail is a very simple task. However, while writing custom applications with form region fetching data from web services or other business object layers, often it is a big performance overhead to fetch these info on form region load. Rather, it's much better to sync up with Outlook's Send/ Receive process and pre-fetch the data and cache it accordingly. Oops, now this is simple too but trust me, difficult to locate this island of information. Lets see how it is done:

A simple routine to create a mail is as follows:

Mail

NameSpace oNameSpace;

oNameSpace= oApp.GetNamespace("MAPI");

oNameSpace.Logon(<Profile>,<Password>,false,false);

MailItem newMail = Application.CreateItem(Outlook.OlItemType.olMailItem);

newMail.To = toValue;

newMail.Subject = subjectValue;

newMail.Body = bodyValue;

newMail.SaveSentMessageFolder = oOutboxFolder;

newMail.Send();

To sync with Outlook's event, try this out:

Syncing up with Send Receive

SyncObject mySyncObject = this.Application.Session.SyncObjects[1];

mySyncObject.SyncStart += new Microsoft.Office.Interop.Outlook.SyncObjectEvents_SyncStartEventHandler(mySyncObject_SyncStart);

mySyncObject.SyncEnd += new Microsoft.Office.Interop.Outlook.SyncObjectEvents_SyncEndEventHandler(mySyncObject_SyncEnd);

mySyncObject.OnError += new Microsoft.Office.Interop.Outlook.SyncObjectEvents_OnErrorEventHandler(mySyncObject_OnError);

void mySyncObject_SyncStart()

{

  //TODO--MessageBox.Show("SyncStart");

}

void mySyncObject_SyncEnd()

{

  //TODO--MessageBox.Show("SyncEnd");

}

void mySyncObject_OnError(int Code, string Description)

{

  //TODO--MessageBox.Show("SyncError");

}

Simple and fun. Hope it helps you folks.
