Sharing your Outlook calendar with colleagues, family members, or assistants is one of the most practical ways to improve coordination and reduce scheduling confusion. Whether you want to share your full calendar or just your availability, Outlook offers flexible sharing options for every situation. This step-by-step guide covers exactly how to share your calendar in Outlook on Windows and Mac.
Understanding Outlook Calendar Sharing Options
Before sharing, it’s important to understand the permission levels available: Can view when I’m busy — shows free/busy status only, no event details. Can view titles and locations — shows event names and locations but not full details. Can view all details — shows complete event information. Can edit — can create, modify, and delete events on your calendar. Delegate — can act on your behalf, accept/decline meetings, and manage your calendar (typically for assistants). Choose the appropriate level based on who you’re sharing with and what they need to see.
How to Share Your Calendar in Outlook (Windows)
Method 1: Share Calendar via Email Invitation
In Outlook, click the Calendar icon in the navigation pane. Go to Home tab → Share Calendar. In the dialog that opens, type the email address of the person you want to share with. Select the permission level from the dropdown. Check “Request permission to view recipient’s Calendar” if you want mutual sharing. Click Share. The recipient will receive an email invitation to view your calendar — when they accept, your calendar appears in their Outlook sidebar.
Method 2: Calendar Properties (More Control)
In the calendar navigation pane, right-click your calendar → Properties → Permissions tab. Click Add to add people from your address book. Set permission levels for each person individually. This method gives you a complete view of who has access to your calendar and lets you manage multiple sharing relationships from one place. Click OK to apply all changes.
How to Share Your Calendar in Outlook for Mac
On Mac, open Outlook and click the Calendar view. Find your calendar in the sidebar and right-click it → Sharing Permissions. Click the + button to add people. Enter their email address (they must be in your organization’s directory or Global Address List for full sharing). Set the permission level. Click Done. Recipients will receive a sharing invitation by email.
How to Share Your Calendar via Outlook Web (OWA)
Go to outlook.office.com and click the calendar icon. In the left panel, hover over your calendar name and click the three-dot menu → Sharing and permissions. Enter the email address to share with, select the permission level from the dropdown, and click Share. For sharing outside your organization, select “Can view all details” as the maximum external sharing level (editor access is typically restricted to internal users).
Sharing Calendar with External Users
When sharing with someone outside your Microsoft 365 organization (e.g., a client, partner, or personal contact), the sharing options may be limited by your organization’s IT policies. External users can typically see your free/busy information or event titles at most. To share full details externally, you may need to publish your calendar to the internet: right-click calendar → Publish to Internet (if available) to get a sharable ICS link that works with any calendar app (Google Calendar, Apple Calendar, etc.).
How to View a Shared Calendar
When someone shares their Outlook calendar with you, you’ll receive an email with an “Open this Calendar” button. Click it to add the shared calendar to your Outlook sidebar under “Other Calendars” or “Shared Calendars.” You can toggle shared calendars on/off in the view by checking/unchecking them in the sidebar. View multiple calendars simultaneously in overlay mode (they appear as colored overlays on your calendar view) by clicking the left arrow on a calendar in the sidebar.
Frequently Asked Questions (FAQ)
Can I share my Outlook calendar with someone who uses Google Calendar?
Yes, with some limitations. You can publish your Outlook calendar as an ICS subscription link that Google Calendar can import and subscribe to. In Outlook, right-click your calendar → Publish to Internet → Publish → copy the ICS link. In Google Calendar, go to Other calendars → From URL and paste the link. Note that free/busy sharing between Exchange and Google Calendar has limited real-time sync — updates may be delayed by hours. For real-time sharing, both parties should be on the same platform if possible.
How do I revoke calendar access?
Right-click your calendar → Properties (Windows) or Sharing Permissions (Mac) → find the person in the permissions list → remove them or change their permissions to “None.” In Outlook Web, go to calendar sharing settings, find the person, and click the X to remove their access. Changes take effect immediately.
