PGP Desktop Recover Blocked Email

I am using Windows XP with Outlook 2007 and PGP Desktop 10.1.  Whilst sending an e-mail I manually blocked the e-mail by mistake.  I need to recover the blocked email.  When an email is blocked by PGP it is no longer present in the drafts folder, outbox or sent items in Outlook.  Does PGP store the e-mail somewhere?  Any help would be greatly appreciated.
