Sync Google Calendar and Outlook
Calensync copies events between Google Calendar and Microsoft Outlook, in either direction. A meeting on one calendar blocks the other, and you choose whether the copy shows the real title or just Busy.

Both directions
Sync Outlook to Google, Google to Outlook, or both. Updates and cancellations follow the original event.
Private when you want
Copy the full event, or mask the title, location, and guests as Busy so a work calendar only shows that you are unavailable.
Apple and ICS too
The same rule can include Apple Calendar. iCalendar (.ics) feeds, such as Proton, can be a read-only source.
How it works
1. Connect both accounts
Sign in with Google and with Microsoft. Calensync uses OAuth and does not see your password.
2. Choose the calendars
Pick the Outlook calendar as the source and the Google calendar as the destination, or the other way around.
3. Create the sync rule
Keep event details, or show Busy. New and changed events are copied automatically.
