Error during MS Office Recurrence rule parsing

Hello!

We’ve faced another issue with recurrence rule parsing for MS Calendar event.
The rule pattern is next:

String pattern = "DTSTART:20200921T010000\n" +
        "DTEND:20200921T013000\n" +        "RRULE:FREQ=WEEKLY;UNTIL=20210315T010000Z;INTERVAL=2;BYDAY=MO;WKST=SUEXDATE;TZID=AUSCentralStandardTime:20201130T103000";
    MapiCalendarRecurrencePatternFactory.fromString(pattern);

Executing fromString method throws such error:

The string of a recurrent rule does not correspond to the standard: options of a rule  is not retrieved
AsposeException: The string of a recurrent rule does not correspond to the standard: options of a rule  is not retrieved

  at com.aspose.email.CalendarRecurrence.<init>(SourceFile:89)
  at com.aspose.email.MapiCalendarRecurrencePatternFactory.fromString(SourceFile:1043)

If I delete the last part of pattern there will be another exception:

String pattern = "DTSTART:20200921T010000\n" +
        "DTEND:20200921T013000\n" +        "RRULE:FREQ=WEEKLY;UNTIL=20210315T010000Z;INTERVAL=2;BYDAY=MO;WKST=SUEXDAT";
    MapiCalendarRecurrencePatternFactory.fromString(pattern);

Incorrect option value ‘BYDAY’ a recurrent rule: ‘SUEXDATE’

Could you please take a look at these issues?

Thanks!

Hi @tahir.manzoor,

Unfortunately I don’t have an input file as event data is retrieved using API. Recurrence rule pattern is computed programmatically.
So PFA AsposeTest.zip (67.3 KB) archive that contains source code with issue.

Hope that will be enough to find a problem.

Thank you!

The pattern string has a mistake, WKST and EXDATE is mixed. So, you faced this issue.

;WKST=SUEXDATE;TZID=AUSCentralStandardTime:20201130T103000

The EXDATE part of rule must not be included to RRULE option as shown below:

String pattern = "DTSTART:20200921T010000\n" +
      "DTEND:20200921T013000\n" +
      "EXDATE;TZID=USCentralStandardTime:20201130T103000\n" +
      "RRULE:FREQ=WEEKLY;UNTIL=20210315T010000Z;INTERVAL=2;BYDAY=MO;WKST=SU";
MapiCalendarRecurrencePatternFactory.fromString(pattern);
