Ever want to add some comments to a message which you have received? Normally Outlook does not allow received messages to be edited - but you can bypass this read-only feature.
In Outlook XP: Open up the desired message by double-clicking.
Select "Edit Message" from the "Edit" menu.
Now just go ahead and edit the message as desired.
