Outlook 2007 is legacy email client witch is not used any more in any new installations. We need proper update for gpgOL. I know that Outlook is propriatery bulls1tt but any way if you have gpgOL you should update this asap! Outlook 2010 is now 2 yeas old and still waiting.
Could you do full MAPI support to Thunderbird so we could dump Outlook for good.
