To do this, you'd have to be sure that the reader is using Word to read Rich
Text messages.  If that condition is satisfied, then you can run this macro
with the e-mail already open:

Sub ConvertToTable()
   Dim objWord As Word.Application, objDoc As Word.Document
   
   Set objDoc = ActiveInspector.WordEditor
   Set objWord = objDoc.Application
   objDoc.Select
   objWord.Selection.WholeStory
   objWord.Selection.ConvertToTable (" ")
   
   Set objDoc = Nothing
   Set objWord = Nothing    
End Sub
