on Android, there is an app which enables you to read (and deal with) the Outlook invitation you may receive (.ics files) This app is named Invitation processor https://www.youtube..../watch?v=FHjmOs3fMx0
How come that it is not possible to have the same little piece of software on Windows for at least displaying a given invitation (be it .ics or .ical) in plain and clear language?
For non Outlook users, such as all those using The Bat, it is a nightmare.
The syntax of the invitation is seen there http://www.faqs.org/rfcs/rfc2445.html
It should be a standalone little app, on which you just drop an .ics attachment...
Just my 2 eurocents..
