Calendar Sharing

Share an Outlook calendar with other people

If you have an Exchange, Office 365, or account, you can send a sharing invitation to other users so they can view your calendar in their own Calendar list.

Calendar sharing isn't limited to the default Calendar folder that is created in all Outlook profiles. You can create additional calendar folders and choose which of those folders to share. For example, you can create a calendar folder for a specific project and share it with your co-workers. Optionally, you can grant them permission to modify the events and appointments in the calendar.
