How to Exclude a particular Date while creating a

Question

I want to Create a recurring Ical Event in Outlook and I have used RRule please see below

RRULE;BYDAY=SU;WKST=MO:FREQ=MONTHLY;INTERVAL=1;UNTIL=20151204T110000

So above will make an event every 04th of month until December 2015

Now in Outlook calendar I dont want to create event on October 4th.

Say like it is a recurring event from September to December on 4th Date, But I dont want event to be cerated in October.

How to achieve this? Can we exclude any date while making recurring event/ any other value we need to add in RRULE?

Your help is much appreciated. Please see below .ics file

You want to use an EXDATE property for each of the dates that you want to exclude. See http://tools.ietf.org/html/rfc5545#section-3.8.5.1
