New to this forum, but trying to find a way to programatically group mail
items in a folder by the subject (i.e. want to export mail folder into a
threaded discussion forum).

When I am in Outlook and I sort by Subject, it knows that the 'Subject 1'
email 'belongs' with 'Subject 1' and 'Subject' etc.

How can I do this programatically so I can export it into my threaded
discussion forum.
