Enabling or disabling bidirectional calendar sync

With automatic bidirectional syncing,  the Zoom meetings that you create or update on either Zoom or supported external calendars will automatically sync across all integrated applications, such as the Zoom web portal, Zoom Workplace app, and integrated calendars. Once you integrate your external calendar with Zoom, bidirectional syncing is enabled by default. If bidirectional sync is enabled, Zoom will store the third party calendar access token on Zoom Cloud.

Note: Bidirectional sync is being gradually rolled out to all paid users, with full rollout expected by the end of September 2026.

Requirements for enabling or disabling calendar event syncing

• Calendar and contacts integration configured for Google, Office365, or Exchange (excluding on-premises)

Limitations of bidirectional calendar sync

• Meetings with registrations and meetings using Personal Meeting ID (PMI) are not fully supported
• Not supported for on premise Microsoft Exchange
• The bidirectional sync does not support the following scenarios:
  • When an assistant schedules a Zoom meeting for the host using the add-on but saves it to their own calendar instead of the host's calendar.
  • If the assistant updates or deletes such an event, the changes will not sync to Zoom.

How to enable or disable calendar event bidirectional synchronization

Note: Enabling Bidirectional sync will not make any changes to meetings that have already been scheduled but only affect syncing of newly scheduled meetings and existing meetings that are updated by a user after the switch is enabled.
