Prerequisites

- The necessary permissions to authorize third-party app access on your Google, Microsoft, or Calendly account
How third-party calendar sync works in Zoho Calendar
When you connect an external calendar account, Zoho Calendar establishes a secure connection using the third-party platform's authorization protocol. Once authorized, Zoho Calendar periodically checks for new or updated events and reflects them in your calendar view.
Depending on the integration, sync can be one-way (events flow into Zoho Calendar only) or two-way (changes made in either calendar are reflected in both). Event data such as title, date, time, and description is carried over during each sync cycle.
What syncs and what doesn't
Not all event data transfers across integrations. The table below outlines what you can expect.

Troubleshooting
If your sync is not working as expected, the following common issues may help.
Events not appearing after setup
Check that the correct permissions were granted during account authorization. Try disconnecting and reconnecting the account.

Limitations and considerations
