If the appointment is organized by Alice (organizer) and send to Bob (attendee) you should decline as Bob (attendee):

var decline = invite.Decline("bob@example.com");

This creates an iCalendar entity with Bob's participation status set to Declined:

You must be using incorrect email address when calling invite.Decline("participant email goes here");

email address is correct but I think PARTSTAT=NEEDS-ACTION; course the issue.

What email address you are using?

Could you please zip the original invitation and send to the email address shown in this page footer.
by (301k points)
Email was just sent.
by (1.6k points)
From your email I gather you are using "testapi@churchillcorp.com" as attendee email.

This is not correct. Attendee email is TestAPI@churchillcorp.com.

Comparison is case sensitive on local part (TestAPI) and insensitive on domain part (churchillcorp.com).

Thank you so much it has resolved the issue. but I think email id should not case sensitive.

Local part might be case sensitive, domain part must be case insensitive.

If you need a different behavior: you can iterate over attendees and preform email search in case insensitive manner first.
