Windows Desktop Search the contents of PGP'd emails in Outlook inbox

Hi,

Is it possible to allow (or set it up in a way) Windows Desktop Search (WDS) to index PGP encrypted emails in my Outlook inbox? If this is not possible, is there another way to allow the searching of an inbox in Outlook, ie. once the passphrase has been authenticated and I can view encrypted messages.

Currently when doing a search in Outlook I can search on the sender/subject (unencrypted elements) but the contents of emails are not being matched when searching.

Versions info:

Windows XP

Outlook 2007

PGP Desktop 10.2.0

Windows Desktop Search 4.0
