I just spent a good hour researching and testing to find this via a Microsoft forum thread explaining why our encrypted emails were still getting caught by DLP. We had a mail transport rule setup and a similar DLP rule - but the transport rule allows an exception to quarantine if the email was encrypted. I do not understand why if our transport rule allows an exception for encrypted messages that the DLP policy would fail to work in conjunction with that?
The funny thing is that if we weren't using the "Fancy DLP" stuff via the portal in the the EAC, then editing the Mail Transport rule allows you the option to "Add this to DLP Policy" if you're using the "Simple Exchange Only DLP stuff".
