How to change the "From" address while others view the mail. I used the following code,

Set olApp = CreateObject("Outlook.Application")
Set olNS = olApp.GetNamespace("MAPI")
Set olMessage = olApp.CreateItem(olMailItem)
lMessage.Importance = olImportanceHigh
olMessage.To = Trim(txtTo) = Trim(txtCC)
olMessage.Subject = Trim(txtSubject)
olMessage.BodyFormat = olFormatHTML
olMessage.HTMLBody = Trim(lblHTMLBody)

Is their is any way to display a different label other than my email address while others view my email.
