How to Share a Private Calendar in Outlook

To share a private calendar in Outlook, open Calendar, choose Share Calendar, enter the recipient’s email address, select what they can see or change, and send the invitation. The calendar stays shared only with the people you invite; it is not made public. Before you begin, decide whether recipients should see event details or only your availability, and remember that sharing a calendar is separate from marking individual appointments as private.

What You’ll Need

An Outlook account with a calendar you own or permission to manage its sharing settings. Work and school accounts may be governed by Microsoft 365 administrator policies.
The email address of each person you want to invite. For the smoothest setup, use the address associated with their Microsoft 365, Outlook, or work account.
A decision about the access level: availability only, limited event information, full details, or editing access. Give people only the access they need.
Access to Outlook on Windows, Outlook on the web, or Outlook for Mac. The labels and exact locations of sharing controls vary slightly between versions.

Step-by-Step

Open the calendar you want to share. In Outlook for Microsoft 365 on Windows, select the Calendar icon in the navigation bar. If you have more than one calendar, check the calendar list and identify the one you own, such as Calendar or a separately created calendar. Select it before sharing so you do not accidentally invite someone to the wrong calendar. In Outlook on the web, open Outlook in your browser and select Calendar from the app navigation.
Open the sharing controls. In new Outlook for Windows, select Share Calendar from the Calendar ribbon. In Outlook on the web, select the calendar in the left-hand list, then choose Share or Sharing and permissions; the wording can depend on the current layout. In classic Outlook for Windows, select the calendar, open the Home tab, and choose Share Calendar. If you use Outlook for Mac, select the calendar, then use the calendar’s context menu or the Share control to open its sharing options.
Choose the correct calendar in the sharing panel. If Outlook asks which calendar to share, confirm its name. A personal calendar and a shared or delegated calendar can appear together in the list, so check carefully. You generally need to be the calendar owner, or have an appropriate permission from the owner, to grant access. If it belongs to a colleague or a group, ask its owner or administrator to share it with the recipient instead.
Add the recipient. Type the person’s email address in the sharing field. Select the matching suggestion if Outlook displays one, then add another address if you want to share with more than one person. Check every address before continuing. Calendar invitations can reveal the calendar name and the permission you have chosen, so do not send an invitation to a distribution list or group unless everyone in it should receive access.
Select the permission level. Choose the least access that meets the recipient’s needs. Can view when I’m busy (or a similarly named availability option) lets them see when you are occupied without showing appointment details. Can view titles and locations reveals those fields but not all event information. Can view all details shows the details Outlook makes available for ordinary appointments. Can edit lets the recipient make changes to the shared calendar, so reserve it for someone who should manage appointments with you. Available choices can differ by account type and Outlook version.
Send the invitation. Select Share or Send to issue the calendar invitation. Outlook sends the recipient a message with a link or an option to add the calendar. Sharing is not necessarily complete just because you typed an address; finish the send action and look for a confirmation. If Outlook displays a warning about sharing outside your organization, check the recipient and follow your organization’s rules before proceeding.
Ask the recipient to accept and open it. The recipient should open the invitation while signed in to the account that received it and choose the option to accept or add the calendar. Depending on Outlook, the calendar may appear under Shared calendars, People’s calendars, or another calendar list. They may need to refresh Outlook or reopen the app. If they use a different email address for Outlook, have them tell you which account they are signed into before you resend the invitation.
Confirm what the recipient can see. Ask them to check that the calendar appears and that the permission matches your intention. If they should see only free/busy information, verify that event subjects and locations are not displayed. If they need more or less access, change the permission in the sharing settings rather than sending a public calendar link. Do not use a public link for a calendar intended for a named recipient.
Review access later and remove it when needed. Open the calendar’s sharing or permissions panel to review the people listed and their access levels. Select a person to change their permission, or remove their access if they no longer need it. The exact control may be labelled Remove, Delete, or shown beside the person’s name. Tell the person if access has been withdrawn; Outlook may not remove calendar data or messages they already received, and information they previously copied cannot be recalled.

Sharing is not the same as making an appointment private. Calendar sharing controls who can access the calendar and what permission they receive. An appointment can also have a Private sensitivity setting. Marking an event private is useful when you share a calendar but want to limit the details shown for one appointment. The extent to which a private item is hidden depends on the viewer’s permission and whether they have delegate-level access. Do not assume that marking an event private conceals it from every person who can manage your calendar.

Common Mistakes

Choosing full details when availability is enough. “Can view all details” may reveal subjects, locations, and other event information. For a person who only needs to schedule around you, choose the availability-only option.
Confusing private events with a private calendar. The Private setting applies to an appointment; it does not replace the calendar’s sharing permissions. Set both deliberately when you share a calendar containing sensitive appointments.
Forgetting to send or accept the invitation. Adding an email address to a sharing panel may not finish the process. Send the invite, then have the recipient accept it from the correct account.
Sharing the wrong calendar. Outlook can list several calendars with similar names. Verify the selected calendar before choosing recipients or permissions.
Giving edit access unnecessarily. An editor can change or add items, which may cause confusion if the recipient only needs to see your schedule. Start with view access and increase it only when required.
Assuming a recipient can share the calendar onward. A recipient’s ability to pass access to other people depends on their role and the account’s settings. If you need to control access, grant it directly to each intended person and review the permissions list.

Tips

Use availability-only access for scheduling. It lets a colleague find a suitable meeting time without exposing the reason for personal or confidential appointments.
Use a separate calendar for a specific purpose. If you want to share only project dates, create a dedicated calendar and put those events there instead of exposing your full personal schedule. Confirm which calendar is selected before sending an invitation.
Check the recipient’s account first. When someone says the invitation is missing, confirm the exact email address and the account they use in Outlook. An invitation sent to one address may not automatically grant access to a different account.
Review permissions when roles change. Remove former colleagues or collaborators who no longer need access. This is especially useful for calendars containing work, family, or appointment information.
Keep sensitive information out of event titles when possible. Even with careful sharing settings, meeting details may be visible to people with broader permissions or through delegated access. Use neutral titles when appropriate, and check your organization’s confidentiality policies.

Troubleshooting

The Share Calendar button is missing or disabled. Check that you are in Calendar and have selected a calendar you own. A calendar shared with you may not let you invite additional people. In a work or school account, your Microsoft 365 administrator may restrict external sharing or sharing altogether. Ask the calendar owner or administrator to confirm what permissions are allowed.

The recipient did not get the invitation. Verify the email address, then ask the recipient to check junk mail and any focused or other inbox tabs. Confirm that your sent invitation was actually sent, not left as a draft. If the address was wrong, remove or correct the entry in the sharing panel and send a new invitation to the right account. Avoid sending repeated invites to several addresses unless you know which one the person uses.

The invitation was accepted, but the calendar is not visible. Ask the recipient to open Outlook using the invited account, refresh the calendar view, and check the shared or people’s calendars section. They can close and reopen Outlook if the list has not updated. If the calendar still does not appear, remove the recipient’s permission and share it again, then have them accept the new invitation. For a work account, check whether the recipient’s organization allows calendar sharing across tenants.

The recipient sees only busy blocks or not enough detail. Open the sharing settings and confirm the permission assigned to that person. If the recipient has availability-only access, change it to the appropriate detail level and save or resend the update if Outlook prompts you. Also check whether the item itself is marked Private; private-item handling can limit what a viewer sees even when the calendar permission allows more detail.

The recipient can see more than intended. Lower their permission or remove their access immediately, then check whether they have delegate access through another route, such as a mailbox permission or a second calendar share. Changing calendar permissions does not erase details they already saw, copied, or received in notifications. If sensitive work information is involved, follow your organization’s incident-reporting process.

Sharing with someone outside your organization fails. External sharing can be blocked by your organization, the recipient’s organization, or the account type. Try the recipient’s correct work or Microsoft account address, but do not bypass a policy by publishing a calendar link. Contact your Microsoft 365 administrator if the organization needs to allow external sharing.

Frequently Asked Questions

Can I share an Outlook calendar with just one person?
Yes. Enter that person’s email address in the sharing panel and select the permission they need. The calendar is shared with the people you invite, not everyone who has the link, unless you separately create a public link.

Can someone see my private appointments if I share my calendar?
It depends on their access level and whether they have delegate or other elevated permissions. A Private appointment is intended to limit its details for ordinary viewers, but it is not a guarantee against access by someone who can manage your calendar. Use the least-permissive sharing level and avoid placing sensitive information in event details.

Can I let someone see my schedule without showing event names?
Usually, yes. Choose Can view when I’m busy or the equivalent availability-only option. The recipient can see occupied time but should not see the titles and locations of ordinary events. Exact behaviour can vary with account settings and access granted elsewhere.

Can the person I invite edit my calendar?
Yes, if you grant Can edit or the equivalent editing permission. That access is broader than viewing and can allow changes to calendar items. Give it only to someone who is meant to add or modify appointments, and review the permission later.

Does sharing a calendar also share my email?
No. Calendar sharing grants access to the selected calendar, not automatically to your inbox. However, mailbox delegation or separate mailbox permissions are different settings and may provide wider access. Check those separately if you are concerned about what a delegate can see.

How do I stop sharing my calendar?
Open the calendar’s sharing or permissions panel, find the person, and remove their access. You can also lower their permission instead of removing it entirely. The change prevents future access through that permission, but it cannot retrieve details the person already viewed or copied.
