Comment 2 for bug 1580500

This would be indeed a nice addition. Currently when I receive a event invitation send by outlook, the message looks empty when opening it. In the main view it shows the message has an attachment and when looking at the source you can see that it is an calendar item from based on the Content-Type: text/calendar; charset="utf-8"; method=REQUEST.

But if you can not guess this from the subject, it is hard to know what the content of the mail is. It would be great if there is at least an indication that this is an calendar item. Integration with the Calendar app would also be great.
