Hi Sébastien,
My understanding was that the way of working you describe imports a snapshot of the calendar and not a permanent sync to it. I want the live Moodle calendar to appear in Outlook. The way I described (which is the way the Moodle documentation says to do it) always gets an error saying there are no appointments in the Moodle calendar. It does import it into Outlook but without any appointments in it.
Thanks
Bob
