Keep your Outlook and Google calendars in perfect sync so people always see your true availability—no more double bookings.
Let's start by teasing out the difference between calendar syncing and calendar sharing.
When you share your Google, Outlook, and iCloud calendars with each other, only you can see the events. People will see you as free in Microsoft Scheduling Assistant or Google Find a Time and double book you. You can learn how to see your Google calendar in Outlook here.
When you sync your calendars, Multical copies the events over in real-time so that people see your true availability.
With a one-way sync, Calendar A gets updated whenever an event is added to Calendar B.
With a two-way sync, Calendar A gets updated whenever an event is added to Calendar B, and Calendar B gets updated whenever an event is added to Calendar A.
You can customize your syncs to be one-way or two-way, depending on your needs.
P.S. There is a free way to one-way sync your Outlook and Google. However, it can take up to 48 hours to synchronize.
Multical syncs Google and Apple iCloud calendars in addition to Microsoft Outlook, Office 365, and Live calendars. The same logic works if you want to sync your Outlook calendar to Google calendar or if you just have multiple Google calendars you want to automatically sync.
