Hi, I understand your situation and your motivation quite well. I work in an Outlook-centric corporation too.

While I like your approach of increasing compatibility for the benefit of yourself and or other users - I have contributed to Rocco's attempts at increasing Sun mailtool compatibility - I am totally pissed at Outlook. For years has it been breaking threads itself (IIRC), has never been able to display emails in a threaded manner until recently. And here comes the most popular new feature (I have seen polls) of Office 2010: Threaded mail view! Welcome, Microsoft, to the world of proper email. 20 or so years later than everyone else. And guess what: 20 years of well established standards, and Microsoft prefers to implement their own junk. If Microsoft weren't so wide spread, we would just leave them to suffer. But ... oh well. Enough rant. Had to get rid of that. *phew* Moritz
