Outlook has no macro recorder, all macros in Outlook are coded using
VBA code.

For information on creating a button and assigning a macro to it see
http://www.slipstick.com/outlook/toolbar.htm#macro

Open Outlook VBA by clicking Alt+F11. Insert a code module using
Insert, Module. In that code module place a Sub. In that Sub use code
something like this:

Sub ForwardItem()
   Dim oExplorer As Outlook.Explorer
   Dim oMail As Outlook.MailItem
   Dim oOldMail As Outlook.MailItem

   Set oExplorer = Application.ActiveExplorer
   If oExplorer.Selection.Item(1).Class = olMail Then
       Set oOldMail =  oExplorer.Selection.Item(1)
       Set oMail = oOldMail.Forward
       oMail.Recipients.Add "address you want it sent to"
       oMail.Recipients.Item(1).Resolve
       If oMail.Recipients.Item(1).Resolved Then
           oMail.Body = "my added text" & vbCRLF & oMail.Body
           oMail.Send
       Else
           MsgBox "Could not resolve " &
oMail.Recipients.Item(1).Name
       End If
   Else
       MsgBox "Not a mail item"
   End If

Be aware that secure versions of Outlook will fire the security
prompts on accessing the Recipients collection and on Send telling you
that a program is accessing your address book and that a program is
trying to send email. Avoiding those prompts is a matter of advance
programming.
