Comment 35 for bug 849416

First, I'm glad I'm not the only one seeing this bug.

Without looking at the code (I'll be doing that shortly), my hypothesis is that Thunderbird only displays one text/* multipart MIME part, and Outlook invitations are sent with text/plain, text/html and text/calendar. The code needs to be changed to "teach" Outlook that text/calendar should be presented as a file attachment, not "ignored" when displaying the text/html or text/plain.

Now, to see if I can come up with a fix ...
