I am working with an Outlook plugin called Titus, that is writing custom x-header information into messages. I would like to apply EV custom filtering based on this information to control the retention period or decide not to archive certain based on what is in these x-headers.
Using OutlookSpy I am able to see the headers are in 0x007D001F / PR_TRANSPORT_MESSAGE_HEADERS_W.
I have used Rob's excellent explanation of custom filtering (https://www-secure.symantec.com/connect/articles/c...), but I'm unable to get it working with the x-header information.
I couldn't find any examples of anyone else filtering based on x-headers, so I'm not even sure it's possible to do.
Can anyone give me advice on how to grab this out or share an example of this working in their environment?
Thanks!
