I had something similar so perhaps this helps: If you still have a google account that has the “calendar” feature enabled, this will lead to google sending invite acceptance emails. Especially if you have a business account (which was my experience,) where you verified the domain. The solution for me was to disable “calendar” as a service on the entire account. Realize that “google calendar” and “google mail,” are technically distinct services. However that doesn’t seem to stop “calendar” from sending emails on your behalf.
