Similary, a few years ago (Nov/Dec 2005, I believe) I notified Microsoft about some CSRF flaws in OWA 2003. Sending a message, deleting a message, and logging out were all vulnerable. An attacker could trick a victim into sending an insult to her bosses (that would show up as an "internal" message) and removing the message from her Sent Items folder. Clearing the deleted items folder, or removing a single message from the deleted items folder, did not appear to be vulnerable(!). Microsoft said the flaws were fixed in Exchange 2007 but I have no way of verifying that. -Peter
