Hi, Currently, the gem doesn''t produce valid ical data for outlook to happily parse. Had to change line 52 in event.rb: old- ical_property :seq, :sequence new- ical_property :sequence same with journal.rb line 30, todo.rb line 31 that now produces data that will open in iCalendar + Outlook and can be validated using the iCalendar validator ( http://severinghaus.org/projects/icv/) -- Regards, Matt Didcoe mattman at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
