Delete calendar invite e-mail after RSVP

Via a Power Automate flow it is possible to automatically respond to a calendar invite. The flow in this article shows how you can also delete the calendar invite e-mail after you have RSVP’d.


This question from aishak12:

I want to accept a meeting invitation and then delete the invitation to from “Inbox” to “Deleted”. Right now the accept meeting invitation is working however it is not deleting the invite.

Calendar invite e-mail not deleted

The Respond to an event invite (v2) action is very easy to use to auto-accept calendar invites. Unfortunately, the original calendar invite e-mail does not get deleted, after the invite has been accepted.


In the interface the calendar invite e-mail does get deleted. This is to avoid confusion that you have not responded yet. With Power Automate you would want that same behaviour.

$Filter eventMessage on subject

The challenge with this scenario is that the When an new event is created trigger action does not contain a link to the related event message. Luckily, the Graph API has the eventMessage resource type.

With the Get eventMessage method it is possible to retrieve events. You can combine that with a $filter query parameter which uses the subject value to find the correct eventMessage via the Graph API.

Flow setup


1. Add a When a new event is created (V3) action.
In this setup I am using a trigger condition to make sure that only invites with a certain subject are auto-accepted.


a. Select your Calendar
b. In the Settings add the trigger condition from the code snippet below

2. Add a Respond to an event invite (V2) action.


a. In the Event Id use the Id of the trigger action
b. Select Accept as the Response
c. Provide a value for the Comment.
d. Select Yes as the Send response?

3. Add a Send an HTTP request action.


a. Use the URI from the code snippet below

b. Use the GET Method

4. Add a Delete email (V2) action.


a. Use the expression from the code snippet below for the Message Id

That is it for the setup of this example.

Happy testing!
