I get this error from Outlook whenever I create a recurring appointment as Daily, Every 2 Days.
I use the WPF version of the classes to create an ical file, containing the following record, which I think is incorrectly formatted.
DTSTART;TZID=E. Australia Standard Time:20111225T050000
DTEND;TZID=E. Australia Standard Time:20111225T120000
The error occurs when I try to import the file into Outlook.
