Share a calendar using GSSMO
With G Suite Sync for Microsoft® Outlook® (GSSMO), you can easily share calendars with other G Suite users, both within your organization and publicly.
People can view your calendar either in Outlook or from their Google Calendar account in a web browser. You can publish a view-only calendar, where you manage events that others can see. Or you can let other people schedule events, as well.
Share a calendar publicly
If you're sharing a calendar publicly or across your organization, send the address as an Apple® iCal® link, which people they can use to access the calendar. For details on how to find the link, see Create & manage a public Google calendar.
Share your calendar with specific people
For details on how to share your calendar with specific people, see Share your calendar with someone. If you share a calendar with a person, the calendar appears in their Outlook navigation pane. You don't have to send them the address.
