No mail invitation send for appointment with thunderbird (CalDAV)

Hello,

When i create an appointment on lightning in thunderbird, i can’t send an email notification of the appointment.

I have the latest version of owncloud and thunderbird.

When i create an appointment on the Web Interface of owncloud, i receive a notification email.

Can you help me ? :slight_smile:

Thanks you

Why do you thing this is related to ownCloud?

Maybe its related to https://github.com/owncloud/core/issues/23600
