How to send invitations to existing Proton Calendar events

You can invite anyone to an event you created in Proton Calendar(ventana nueva) by adding them as participants. Adding participants is possible when you create an event or later by editing the event.

To add participants to an existing event in Proton Calendar, you need to have created the event. You will show up as the organizer of this event.

This feature is currently available on our web and Android apps.

Adding participants to an event

First, select the event in your calendar and choose the option Edit. Scroll down to the Add participants field, where you can add the participants’ email addresses. 

When you start typing an email address, you will see a list of suggestions. This includes your Proton Contacts list and alternative email providers. To make a selection, click on the email address you would like to send an invitation to or use your keyboard Up/Down and Enter keys.

Once you’ve entered their email address, you can specify if the participant’s attendance is optional. To do this, click on the contact icon next to their email address. In this case, their email invitation will mention: “Your attendance at this event is optional.”

Your name and email address will also show up in the list of participants as an Organizer. The other participants will receive the email invitation from this email address.

To delete one of the participants from the list, click on the trash icon next to their email address.

Sending invitations

Once you’ve added all the event’s details and the participants’ email addresses, Save the event to send the invitations to all participants.

When a participant answers your invitation, you will receive a confirmation email and the event will update in your calendar. If the event hasn’t updated to reflect the participant’s response, try opening the confirmation email — this should automatically update the event. 

You can add up to 100 participants to an event. Later, you can update or cancel the invitation to your event(ventana nueva).

Please note that adding participants to events imported from a different calendar to Proton Calendar isn’t possible.
