I am facing one issue i.e. my email protection rule is not working when I am using MS Outlook 2010, where as in the same environment with MS Outlook 2007 the rule is working fine. FYI the DLP agent build version is 18.104.22.1682.
The issus is solved.
Two things to be done.
Installed Patch 1 of HDLP agent
Enable DLP add on in the MS Outlook 2010.
