Overview
This guide explains how to create a new calendar in Microsoft 365 Outlook and share it with another user so both people can view and edit it. Steps are provided for Outlook on Windows, Mac, and Outlook on the Web (OWA).
NOTE: This guide covers sharing a calendar between users within the same Microsoft 365 organization. Sharing with external users requires your administrator to enable external calendar sharing first.

These steps are performed by the person who will own and create the shared calendar.
Step 1 - Create a New Calendar in Outlook for Windows
- Open Outlook and click the Calendar icon in the left navigation pane
- In the left pane, right-click My Calendars and select New Calendar
- Give the calendar a descriptive name (example: Team Schedule) and click OK
- The new calendar will now appear under My Calendars in the left pane
Step 2 - Share the Calendar in Outlook for Windows
- Right-click the new calendar you just created under My Calendars
- Select Sharing Permissions
- Click Add and search for the person you want to share with by name or email address

These steps are performed by the person who received the calendar sharing invitation.
Step 5 - Accept the Invitation in Outlook for Windows
- Open your email inbox and locate the calendar sharing invitation
- Click Accept or Open this Calendar

Step 6 - Accept the Invitation in Outlook for Mac
- Open your email inbox and locate the calendar sharing invitation

Step 7 - Accept the Invitation in Outlook on the Web (OWA)

Notes
- If the shared calendar does not appear automatically after accepting, try closing and reopening Outlook
- In New Outlook for Windows, secondary shared calendars may not always appear in the directory search - if this happens, ask the calendar owner to resend the sharing invitation and accept it directly from the email
- Both users must be in the same Microsoft 365 organization for instant syncing to work - changes made by one person will appear for the other in real time
- To stop sharing the calendar at any time, the owner can right-click the calendar, select Sharing Permissions, select the person, and click Remove
- Permission levels available are: Can view when I'm busy, Can view titles and locations, Can view all details, and Can edit
