It works, but it doesn't open automatically calendar .ics info when there are more than one contents in winmail.dat, even if the "Open calendaring data directly" option is checked.
I often receive Outlook mails with appointment (.ics) + rtf description: Lookout doesn't prompt to add to calendar the event.
The only (annoying) workaround is to save the .ics file and import it manually.

This review is for a previous version of the add-on (1.2.7).
