What’s changing

In June of 2024, we introduced an improved email notification experience between Google Calendar and third-party calendar services, like Outlook, via beta. Beginning today, this update is now generally available.

Specifically, this update addresses feedback we’ve heard from our customers regarding the syncing experience from Google Calendar to third-party calendars. Event guests will now enjoy a more reliable syncing experience and less calendar emails in their inbox. 
  • Google Calendar will send additional filterable emails to improve event sync accuracy when users make updates to recurring events. 
  • Email notifications purely intended to sync information will be easily filterable by the recipients. They will display a banner in the email body with instructions on how to create inbox filters to hide similar emails, which can help to minimize clutter in recipients’ inbox.
  • At scale, Outlook system administrators can use Microsoft’s Powershell to implement an email filter rule for these messages for all users.


Additional details

With this release, we have also updated a user invisible email header, Envelope-Sender address (also called Return-Path or bounce) to improve reliability of DMARC alignment when delivering to third-party recipients.
