Book Google Workspace resources from third-party calendars
Organizations that use both Google Workspace and other calendaring systems, like Microsoft Outlook, can now more easily coordinate shared resources, such as rooms, projectors, or company cars. We are introducing an open beta that allows non-Google users to book Google Workspace resources directly from their preferred calendar service.
Google Workspace admins can grant specific non-Google users or entire non-Google domains permission to book Workspace resources. Once these permissions are configured in the Admin Console, non-Google users can reserve a resource by simply adding its email address to the calendar event guest list. If the resource is configured to auto-reply, it automatically accepts or declines the invitation based on its availability and sends an email notification to the organizer.
Additionally, for organizations using both Google Workspace and Microsoft Outlook, admins can configure Calendar Interop. This allows Outlook users to find and book Workspace resources by their name and view their availability before sending an invite.
Getting started
- Admins: This feature is OFF by default and can be configured at the resource level in the Admin console. Admins can specify which non-Google users or entire domains are permitted to book specific rooms. Visit the Help Center to learn more.
- End users: Once an admin has granted permission, non-Google users can book a room by adding the resource email as an attendee to their calendar event.
Rollout pace
- Rapid Release and Scheduled Release domains: Gradual rollout (up to 15 days for feature visibility) starting on April 7, 2026
