RRULE Problems

Hi Aspose

Using the below ICS file and code, running Aspose.Email for Java 17.2, we receive the error 'class com.aspose.email.system.exceptions.ArgumentOutOfRangeException: Specified argument was out of the range of valid values' when creating the MapiMessage. This error is being generated by the RRULE, although the ics file can be dragged into Outlook correctly. Can you please explain what we are doing wrong?

Thanks
