RSVP buttons not showing when sending event invitation via email

[phong.nguyen]

Hi everyone,

I have sent the event invitation to the user via email, the RSVP buttons are not showing and working in the usual way in mail clients.

When I send an invitation from Gmail, RSVP buttons show and work in Thunderbird but not with Gmail & Outlook (Figure 1.1, 1.2, 1.3)

Hope someone can help me understand this problem and how to solve it.

Thank you and best regards,

Can you attach two emails with source code:

1. Email with buttons
2. Email from Espo without buttons

and we can try to help you

Here is where ICS is generated: https://github.com/espocrm/espocrm/b...t/Ics.php#L181

You need to add:

ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS- ACTION;RSVP=TRUE;CN={NAME}:{EMAIL_ADDRESS}

Anyone know where to add yuri code to?
