Google calendar notifications not received by external recipients

[sinisa_k]

Hi,

I am facing an issue when a Google Meet invitation is sent to an external non-Google recipient (O365). The email from calendar-notification@google.com doesn't pass SPF, DKIM, and DMARC. I have in place SPF, DKIM, and DMARC, and all emails sent from our domain are marked with a pass except calendar events sent to external recipients, which are sent from calendar-notification@google.com on behalf of a sender. Our SPF record includes _spf.google.com and DMARC policy is set to reject

Any ideas on how to resolve this issue?

Kind regards,

Sinisa

We are experiencing the same issue with coroprate customers using O365, which is a huge dealbreaker, as we can not invite them to meetings.

I really hope this will get fixed soon.
