How to Share a Personal Calendar in Outlook on Any Device

To share a personal calendar in Outlook, open Calendar, choose the calendar’s sharing option, add the recipient, select what they are allowed to see or change, and send the invitation. You will need to be signed in to an Outlook account that supports calendar sharing; the available permissions and button names can vary between Outlook for Windows, Outlook for Mac, and Outlook on the web.

What You’ll Need

An Outlook account with the calendar you want to share. Sharing is generally supported for Microsoft 365 or Exchange work and school accounts and Outlook.com accounts. A calendar stored only in a local Outlook data file, or attached to some IMAP or POP accounts, may not be shareable.
The recipient’s email address. For the smoothest setup, use the address associated with their Microsoft account or work account, if they have one.
A decision about access: whether the recipient should see only your availability, see event details, or make changes. Share only the detail level they need.

Step-by-Step

Open the calendar you want to share. In Outlook for Windows, select the Calendar icon in the navigation pane. Check the list of calendars and identify your personal calendar; do not select a shared, team, or secondary calendar by mistake. If you have several calendars, select the one whose events you want the other person to see. Sharing a calendar does not automatically share your email or contacts.
Choose the sharing command for your version of Outlook. In classic Outlook for Microsoft 365 on Windows, open the Calendar view, select the calendar, then choose Home > Share Calendar. If the button is unavailable, the account or calendar may not support sharing. In new Outlook for Windows or Outlook on the web, open Calendar and select Share calendar in the toolbar. Choose the calendar from the list if Outlook asks which one to share.
Enter the recipient. Type the person’s email address in the sharing window or people field, then select the matching contact suggestion if Outlook displays one. Check the spelling carefully, especially if the address has a work and personal version. You can usually add more than one person, but set the permission for each person deliberately rather than assuming everyone should have the same access.
Select the least-permissive access that will work. The precise labels depend on the account and Outlook version. Common options include viewing when you are busy, viewing limited details, viewing all event details, and editing the calendar. Availability-only access is suitable when someone just needs to schedule around you. Full details can expose event names, locations, and notes, so choose it only when appropriate. Editing lets the person change calendar items and should be reserved for someone who needs to maintain the calendar with you.
Send the invitation. In classic Outlook for Windows, choose a detail level in the Details menu, then select Send. In new Outlook or Outlook on the web, choose the permission shown for the person and select Share or the equivalent confirmation button. Outlook sends a sharing invitation. The recipient may need to open it and accept the share before the calendar appears in their Outlook.
Ask the recipient to check the correct account and calendar list. They should open the invitation while signed in to the account that received it and accept or add the calendar when prompted. Depending on their Outlook version, it may appear under Shared calendars or in the calendar list. If they use a different email address to sign in, accepting while signed into that other account may not give them access.
Review or change access later. In classic Outlook, open the calendar’s sharing or permissions controls; in new Outlook and Outlook on the web, return to Share calendar and manage the people listed there. Select the recipient to change their permission, or remove their access if they no longer need it. Permission changes may take a little time to appear for the recipient. If you remove access, ask them to close or remove the calendar from their list as well.

Outlook for Mac: Select Calendar and look for Share Calendar on the toolbar or in the calendar’s context menu. Choose the calendar, add the recipient, set their permission, and send or confirm the invitation. The layout and wording vary between Outlook for Mac releases, so if the toolbar command is missing, control-click the calendar name and look for its sharing or permissions option. The recipient still needs to accept the invitation.

Common Mistakes

Sharing the wrong calendar. Outlook can contain a personal calendar, extra calendars, and calendars belonging to other people. Confirm the selected calendar name before sending the invitation.
Choosing full details when availability is enough. Event titles, locations, and notes can reveal personal or confidential information. Busy/free access is often sufficient for scheduling.
Assuming an invitation means access is active. The recipient may need to accept it, and the calendar may not appear until they do. Check that they accepted the invitation rather than sending repeated shares.
Inviting the wrong email address. A person may have several accounts. If access fails, verify which address received the invitation and which account they used to accept it.
Confusing sharing with delegation. Calendar sharing grants the chosen viewing or editing rights. It does not necessarily give someone permission to manage your mailbox, send messages on your behalf, or handle meeting requests as a delegate.

Tips

Use availability-only access for routine coordination. It lets someone find an open time without exposing what each appointment is about. You can share more detail with a specific trusted person if their role requires it.
Share with named people rather than publishing a public link. A public calendar link can be forwarded or exposed beyond the intended audience. If your Outlook account offers calendar publishing, treat a link as accessible to anyone who obtains it and review the privacy implications first.
Explain the invitation when you send it. A short message such as “I’ve shared my calendar so you can check my availability” helps the recipient recognize the invitation and understand what access you intended to give.
Recheck permissions when circumstances change. If a colleague changes roles or a project ends, remove access they no longer need. Also review whether an editor still needs the ability to change events.
Keep private appointments private where possible. A private event setting can limit what calendar viewers see about that event, but how it appears depends on the recipient’s permission and your organization’s configuration. Do not rely on it as a substitute for choosing appropriate sharing access.

Troubleshooting

The Share Calendar option is missing or disabled. Confirm that you selected a calendar connected to a Microsoft 365, Exchange, or Outlook.com account, rather than a local-only calendar. In a work or school account, your organization may restrict sharing, especially outside the organization. Try Outlook on the web with the same account; if the option is still unavailable, ask your Microsoft 365 administrator whether calendar sharing is allowed.

The recipient did not receive the invitation. Check the address, then have them look in Junk or Spam and search their inbox for an Outlook calendar-sharing message. If it was sent to the wrong address, remove that entry and share again with the correct one. Avoid sending many invitations before checking whether the first message arrived.

The recipient accepted, but cannot see the calendar. Ask them to verify they accepted while signed in to the invited account. Have them expand the calendar list and look under Shared calendars. They can refresh Outlook or close and reopen it if the list has not updated. If they use a work account, an organization policy or a cross-organization sharing restriction may prevent access even after acceptance.

The recipient sees busy blocks but not event names. This usually means you granted availability-only or limited-detail access. Reopen the sharing controls, select that recipient, and raise the permission only if you are comfortable sharing more information. The recipient may need to refresh or reopen the calendar after the change.

The recipient can see events but cannot edit them. Viewing and editing are separate permissions. Check the person’s current access and grant edit permission only if they should be able to create, change, or delete calendar items. If the permission is correct but changes are still blocked, check whether the calendar is shared from an account or organization that limits editing.

Frequently Asked Questions

Can I share my Outlook calendar with someone who does not use Outlook?
Often, yes, if your account allows sharing. They may be able to open the invitation or view the calendar through a supported account or app, but features and sign-in requirements vary. For work accounts, external sharing may be disabled by an administrator.

Does sharing a calendar let someone read my email?
No. Calendar sharing controls access to the calendar, not your inbox. Mailbox delegation is a separate feature with different permissions. Check the permission description before sending an invitation if you are unsure what access it grants.

Can I let someone edit my calendar without giving them access to everything?
You can grant calendar editing without sharing your inbox, but editing generally allows changes to calendar items. The exact actions allowed depend on the account and permission settings. Give edit access only to a person who should be able to make those changes.

Can I share only one event instead of my whole calendar?
Yes. If the person only needs information about a single appointment, open that event and invite them or forward its details instead of sharing your entire calendar. Be mindful that a meeting invitation may expose different information or allow responses compared with calendar sharing.

How do I stop sharing my calendar?
Open the calendar’s sharing or permissions settings, select the person, and remove their access. If you shared it with several people, remove each person who should no longer have access. Updates may not show immediately, and a recipient may need to remove the calendar from their own list.

Why can I share with coworkers but not someone outside my organization?
Your Microsoft 365 administrator can limit external calendar sharing for privacy or security. The recipient’s provider and account type can also affect what works. Ask your administrator whether external sharing is permitted; do not use a public link to bypass a restriction.
