Prior to sending a mail in Hotmail, the compose window has an option to retain a copy in the 'Sent' folder. If its not selected, the message will never be stored in the Sent folder.
Note: Hotmail will dump the Sent folder after a period of time if the account is not a fee based account(MSn Premium).
Future questions on Hotmail, though not exactly the correct forum, but as close as it gets, should be posted to the microsoft.public.msn.discussion forum rather than this Vista Windows Mail forum.
Here's a link for nntp access instead of the web interface.
