I receive often emails with big attachment that fill my inbox space very quickly.
On the other side, I usually like both to remove these attach and keep the email to preserve the thread for future use. Outlook 2007 don't have this feature so I wrote the following VBA function I added to a button on my client that resolve easily this task.
TIP: You can select more message at once too. This is useful if you want to clear a big number of messages you already have archived.
Hope this helps!

Note: I already developed this VBA for outlook 2003, but Outlook 2007 requires some small update. following code should work.
UPDATE (09/06/09): Thanks to John Harvey and Patrick Philippot now the procedure save attachments in a specific folder and make good use of outlook memory:-)
UPDATE (22/10/09): Thanks to Steve Evans now it shows a link to folder where the attaches are saved
