I have been using the following to talk to Outlook from Excel

Set OutL = CreateObject("Outlook.Application") 'this will launchOutlook
(Hidden)
Set NewMail = OutL.CreateItem(0)
NewMail.Subject = UserForm1.TextBox1.Value
NewMail.To = ActiveCell.Value
NewMail.Body = UserForm1.TextBox2.Value
NewMail.Send


Is there any parts of Outlook that can be accessed other than "To",
"Subject" and "Body", Ideally I would like to access the Source of the
message body so that I could send HTML to it and create emails that are
formatted?

I am using Office 97
