Google Improves Google Calendar's interoperability with Microsoft Outlook

Google 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 fewer calendar emails in their inbox. 

Building upon this, Google announced 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. 

This feature is available now and for free for any user.
