In other words, if the e-mail address field (typically Email1Address) does not have a value, then the e-mail address can be programmatically changed. If the field already contains an e-mail address, however, the value of the e-mail field will not change and you will not receive an error message.

The following Visual Basic for Applications automation code illustrates the problem:

    Sub ChangeEmailAddress()

      ' The Outlook object library must be referenced.
      Dim ol As New Outlook.Application
      Dim myContact As ContactItem

      ' Create a new Contact item.
      Set myContact = ol.CreateItem(olContactItem)
      myContact.FullName = "Joe Smith"

      ' This will properly set the email address.
      myContact.Email1Address = "joe@abc.com"
      myContact.Save

      ' This will not change the email address.
      myContact.Email1Address = "mike@xyz.com"
      myContact.Save

      ' The email address appears to be changed here...
      MsgBox myContact.Email1Address

      ' ...but it is not actually changed.
      myContact.Display

   End Sub
				

Note that programmatically, the Email1Address will properly return the second e-mail address (mike@xyz.com) until the first e-mail address is resolved.
