Ok, so I figured out most of this with some helpful code from the web. The following code works when I create draft emails. I select the draft or draft that I want to have a "From Field" populated for and run the macro. problem is at this point, I am getting the outlook is trying to send an email on your behalf message that needs to be worked out and I cannot get the macro to run when it is attached to an outlook button. Message: The Macro SendMail cannot be found.
Anyway, here is some code that may be useful to others with a similiar problem with populating the from field.
Sub SendMail()
Dim objApp As Outlook.Application
Dim objSelection As Outlook.Selection
Dim objExp As Outlook.Explorer
Dim objMsg As Object
'dim OlSecurityManager as Outlook.
Set objApp = New Outlook.Application
Set objExp = objApp.ActiveExplorer
Set objSelection = objExp.Selection
'OlSecurityManager.ConnectTo objOLApp
'OlSecurityManager.DisableOOMWarnings = True
'On Error GoTo Finally
For Each objMsg In objSelection
objMsg.SentOnBehalfOfName = "email@domain.com"
objMsg.Display
'objMsg.Send
Next
'Finally:
' OlSecurityManager.DisableOOMWarnings = False
End Sub
