Comment 69 for bug 849416

I'm having this same problem ever since I can remember using Thunderbird, years ago. Look guys, unfortunately MS/Outlook might not follow the industry standards or best practices, but is still what most people use out there. So more people will adopt Thunderbird ONLY when they can receive emails from people that don't use Thunderbird. I'd love to see this issue solved and be able to ditch the OSX Mail client (which by the way properly opens Calendar and other email attachments, even coming from Outlook).
Thanks in advance!
