That makes sense. Except for that one guy who had subfolders in his Trash folder. ;-) I tried to explain him that Outlook supports archiving mails and can even do so automatically, but he - like most of us - is a creature of habit, and I quickly stopped.

All in all, if it works for these users, I am not going to impose my style of organizing my mailbox on them. But using the Trash for that purpose seems dangerous for the same reason using the trash bin in the office as an archive is.
