VCard and ICal are definitions of text-based PIM information in files. In OX terms, VCard defines contact data, while ICal defines both Tasks and Appointments. ICal internally identifies itself as VCalendar 2.0, which illustrates who closely related both protocols are. That is why questions on both formats are answered in one article.

This article deals with features that are in VCard and ICal but are problematic within the OX.

RRULE: "The second last sunday in a month"

ICal allows you to define an appointment with occurs "the second last sunday every month". OX simply does not. We only support counting from the beginning of a month, but not from the end. Since a month might have either four or five occurrences of a certain day, it is not possible for us to simply convert this.
