Improving Google Calendar's interoperability with Microsoft Outlook

Improving Google Calendar's interoperability with Microsoft Outlook
Monday, March 3, 2025

What’s changing
We recently announced an improved syncing experience from Google Calendar to third-party calendars, like Microsoft Outlook, that allows event guests to enjoy a more reliable syncing experience with less calendar emails in their inbox.
Building upon this, we’re excited to announce that Calendar now reliably processes calendaring emails sent using the Microsoft-specific format for rich text emails called Transport Neutral Encapsulation Format (TNEF). As a result, Calendar users and organizations that routinely collaborate with internal and external Outlook users will now benefit from a more reliable experience when receiving invitations and RSVPs from Outlook users.
