About Calendar Interop

As a G Suite administrator, you can use the Calendar Interop tool to allow Microsoft Exchange and Google Calendar to work together. Users in both systems share their availability status so everyone can see each others' schedules.

Administrators can

  • Turn Calendar Interop on for a domain.
  • Allow Calendar users to book Exchange calendar resources, such as meeting rooms, when they schedule a meeting.
  • Use automated tools to verify setup.
  • View error messages and suggestions for resolving those errors.
  • Track cross-system user requests for availability information in the Google Admin console.

Calendar and Exchange users can

  • See each other’s availability information. Availability (only busy blocks are visible to users) and additional event information (titles and locations of events are visible to users) lookups are supported.

    Important: Calendar Interop respects event-level privacy settings. If an event is marked as private in Exchange, the event's details are not visible in Google Calendar. Similarly, if an event is marked as private in Google Calendar, its details are not visible in Exchange.

  • See availability and additional event information of Exchange calendar resources (such as meeting rooms), and also book resources when they create events in Google Calendar.
  • Use Calendar Interop with Google Calendar on Android, Apple iOS, and web clients.
  • Use Calendar Interop with all Microsoft Outlook 2010 and later clients (including desktop, mobile, and web Outlook versions).
