Comment 73 for bug 849416

Added my vote to this - this should be treated as a serious data-losing bug, calendar invites used to be rare (between people in different organisations) since cross system compatibilities were very common, but they are very common these days as they work on every platform EXCEPT Thunderbird. Since the symptom is a blank message with no indication at all that it is a calender invite it means people lose data every day because of it.

Note - I've had two invites, from people in different organisations this week, if I wasn't looking for this bug I'd have lost the invitation thinking they just randomly sent me a blank email, instead of going to Apple Mail to open the invitation.
