One of the quirks of IMAP is that messages are neither deleted immediately when you press Del nor moved to a Trash folder. Instead they are "marked for deletion" until you update the folder (usually by navigating to another folder). IMAP is not a true Active Sync so it leaves the message in the users respective folder until they navigate away from it.
To hide messages already marked for deletion in Outlook:
- Outlook 2010/2013
- Outlook 2003
