UPDATE: A customer reported that the link in his confirmation mail 'click here to join' does not work, because it is missing the ':' after https. We don't know how widespread this is or whether it is a one-off for this particular customer. However, he did report that the the URL in the Outlook invitation/appoint is OK.
