Here is one small, untested, VBA sample based on http://msdn.microsoft.com/en-us/library/office/ff865637.aspx
Sub CreateReplyFromTemplate()
dim currItem As Outlook.MailItem
dim currItemReply As Outlook.MailItem
Dim MyItem As Outlook.MailItem
set currItem = activeinspector.currentitem
Set curritemReply = currItem.Reply
Set MyItem = Application.CreateItemFromTemplate("C:\HelpTopic1.oft")
MyItem.To = currItemReply.To
MyItem.htmlbody = MyItem.htmlbody & currItemReply.htmlbody
currItemReply.close oldiscard
currItem.close oldiscard
MyItem.Display
set curritemReply = nothing
set MyItem = nothing
set currItem = nothing
End Sub
