How to Share a Calendar in the Outlook App on Desktop

To share a calendar in the Outlook app, open Calendar, choose the calendar you own, select Share Calendar or Sharing and permissions, enter the recipient’s email address, set their access level, and send the invitation. You’ll need to be signed in to an account that supports calendar sharing; work or school administrators may restrict it.

What You’ll Need

An Outlook account with a calendar you own or have permission to share. Microsoft 365 work or school accounts and Outlook.com accounts commonly support sharing, but account type and organization settings affect what is available.
The recipient’s correct email address. For people outside your organization, confirm that external sharing is allowed.
A current Outlook app and an internet connection. The labels can differ between classic Outlook for Windows, new Outlook for Windows, and Outlook for Mac.
A decision about what the other person should be able to see or do: availability only, event details, or permission to edit.

Step-by-Step

Open Calendar and locate the calendar. In Outlook for Windows, select the Calendar icon in the navigation bar or app launcher. In the calendar list, identify the calendar you want to share. If you have several, check the name carefully before proceeding. Sharing a calendar does not automatically share every calendar attached to your account.
Choose the sharing command for your Outlook version. In new Outlook for Windows, select the calendar, then use Share Calendar on the Calendar ribbon if it appears. You can also right-click the calendar name and choose Sharing and permissions. In classic Outlook for Windows, open Calendar, select the calendar, and choose Home > Share Calendar on the ribbon. If the ribbon is simplified, expand it or look in the calendar’s context menu.
Enter the person you want to invite. In the sharing window, type the recipient’s name or full email address. Select the matching contact suggestion when Outlook offers one. If Outlook cannot find the person, use the complete address and check its spelling. Add one recipient at a time if you want to set different permissions for different people.
Select an access level that fits the purpose. The available wording varies by account and app, but common choices include viewing when you are busy, viewing titles and locations, viewing all event details, or editing events. Choose the least access that will do the job. For example, a relative coordinating a visit may need full details, while a colleague arranging a meeting may only need your free/busy status.
Check whether you are granting edit access. A person with edit permission can create, change, and delete calendar events, so use it only when you want them to manage entries. Some accounts offer a delegate option or additional settings. A delegate may be able to manage meeting requests on your behalf; that is different from simply viewing your calendar. Do not select a delegate-level role unless you intend to delegate calendar work.
Send the sharing invitation. In new Outlook, select Share or Send after checking the recipient and permission. In classic Outlook, select To to add the recipient, choose a detail level in the message, and select Send. Outlook emails an invitation or sharing message. The recipient may need to accept it before the calendar appears in their calendar list.
Tell the recipient how to open it. Ask them to open the invitation while signed in to the account that received it, then select the option to accept or add the shared calendar. If they use Outlook, it should appear in their calendar list or under shared calendars. The exact placement depends on the Outlook version. If they use another calendar program, the invitation may provide a link or instructions, but the experience and available details can differ.
Confirm the result and adjust if necessary. Ask the recipient to check that the calendar is visible and that the permission level is useful. If they cannot see expected details, return to the calendar’s sharing settings and review their access. In new Outlook, right-click the calendar and open Sharing and permissions; in classic Outlook, use the calendar sharing or permissions controls. Save or send any changes if prompted.

On a Mac: Open Outlook and switch to Calendar. Select the calendar in the sidebar, then look for Share Calendar on the ribbon or use the calendar’s context menu. Add the recipient and choose a permission level before sending. Outlook for Mac’s layout and permission choices can vary with the app version and account type. If the share command is missing, check that the calendar belongs to a supported Microsoft account and try Outlook on the web.

On a phone: Outlook for iOS and Android is useful for viewing calendars and responding to sharing invitations, but it may not show all the permission-management controls available in desktop Outlook. If you cannot find a way to share or change access in the mobile app, use Outlook for Windows, Outlook for Mac, or Outlook on the web instead. The web version usually offers a clear route through Calendar and the selected calendar’s sharing settings.

Common Mistakes

Sharing the wrong calendar. A personal calendar, a work calendar, and a calendar shared with you can all appear together. Verify the calendar name and ownership before you send an invitation. You generally cannot change sharing rights on a calendar that someone else owns.
Granting more access than intended. “Can view all details” reveals more than busy/free availability, and edit permission allows changes. Consider what information appears in event titles, locations, notes, and attachments before choosing a level.
Assuming the calendar is shared as soon as you click Send. The recipient may have to accept the invitation, open it using the right account, or refresh Outlook. Sending an invitation does not guarantee they have opened it.
Using the wrong email address or account. If a person has both a personal and a work address, invite the one they will use to access the calendar. Sending the invitation to an alias they rarely check can make the share appear to be missing.
Expecting an unsupported account to offer the same options. IMAP or POP mail accounts do not provide the same Microsoft calendar-sharing features as Exchange, Microsoft 365, or Outlook.com accounts. A calendar stored locally or owned by another organization may also have limited sharing controls.
Confusing a shared calendar with a meeting invitation. Sharing gives ongoing access to a calendar, subject to its permission settings. Inviting someone to a meeting adds them to a particular event; it does not necessarily grant access to the rest of your calendar.

Tips

Start with limited access. If someone only needs to find a suitable meeting time, free/busy access may be enough. You can raise their permission later if the arrangement requires it.
Share only the calendar they need. For a project, a dedicated project calendar can keep personal appointments separate. Before sharing it, check that you have selected the correct calendar and that the events belong there.
Use separate permissions for separate people. An assistant who schedules events may need edit access, while a teammate may only need to view details. Review each recipient individually rather than giving a whole group broad permissions by default.
Review access periodically. When a project ends or someone changes roles, remove or reduce their access in the calendar’s sharing settings. Removing a person’s permission does not delete the calendar or its events.
Keep private information out of broadly shared event details. Even if you choose a restricted permission level, review event titles and locations for sensitive information. Your organization may also apply its own retention and privacy rules.
Use Outlook on the web as a fallback. If a ribbon button is missing, sign in to Outlook on the web with the same account, open Calendar, and look for the calendar’s sharing or permissions options. This can help distinguish a desktop layout issue from an account restriction.

Troubleshooting

The sharing option is missing or disabled. Confirm that you selected a calendar you own, rather than one listed under another person’s shared calendars. Check whether the account is Microsoft 365, Exchange, or Outlook.com and whether you are online. If it is a work or school account, your Microsoft 365 administrator may have disabled sharing, especially sharing with people outside the organization. Try Outlook on the web; if the control is absent there too, ask your administrator or account support team.

The recipient did not get the invitation. Verify the address and ask the recipient to check junk, spam, and quarantine folders. If the invitation was sent to an alias, resend it to the address associated with their Outlook sign-in. You can also remove the incorrect permission entry and add the correct address again. For external recipients, organizational policies may block delivery or sharing.

The calendar does not appear after acceptance. Have the recipient open the invitation using the account it was sent to and accept or add the calendar. Then ask them to refresh Outlook, check the shared calendars list, and make sure the calendar is selected for display. If they accepted while signed in to a different account, send a new invitation to the account they actually use.

The recipient sees only busy/free information. Return to the permission list and check the level assigned to that exact email address. A more limited permission may have been selected, or the recipient may be opening another calendar that has the same name. Change the permission if appropriate, send or save the update, and have them refresh. Some details may remain unavailable if the account or organization applies restrictions.

The recipient can see events but cannot edit them. Viewing details is not the same as editing. Change their permission to an edit level only if you want them to create or change events. If the edit option is unavailable, check account support and organization policy. A shared calendar can also behave differently across Outlook versions, so have the recipient update the app or try Outlook on the web.

Changes do not appear right away. Allow time for the invitation or permission update to synchronize. Close and reopen the calendar, refresh Outlook, or sign out and back in if needed. Check that you changed permissions on the correct calendar and that the recipient is online. If a work account is involved, ask the administrator whether a policy or service issue is affecting sharing.

Frequently Asked Questions

Can I share an Outlook calendar with someone who does not use Outlook?
Often, you can invite an external email address, but the recipient’s ability to open the calendar depends on the account and sharing settings. They may need a Microsoft account or may receive a link with limited functionality. Your organization can block external sharing, so check with its administrator if the invitation cannot be used.

Can I share my Outlook calendar from the mobile app?
Some mobile app versions provide calendar-sharing options, but the controls are not consistent across accounts and releases. For reliable permission management, use Outlook for Windows or Mac, or Outlook on the web. You can generally use the mobile app to respond to an invitation and view a calendar shared with you.

Does sharing my calendar let someone see every event detail?
No. The permission you select determines what the recipient can see. Busy/free access hides event details, while a full-details permission reveals more information. Review the specific choices shown in your Outlook app before sending, since labels and options can vary.

Can the person I share with change my appointments?
Only if you grant an edit permission or an appropriate delegate role. A view-only permission does not give them authority to edit events. Choose an edit level deliberately, because it can allow the person to create, change, or delete entries.

How do I stop sharing my Outlook calendar?
Open the calendar’s sharing or permissions settings, find the recipient, and remove their access or reduce it to a lower level. The exact control may say Remove, Delete, or show a permission menu. The recipient may need to refresh Outlook before the change is visible.

Why can I share one calendar but not another?
You may own one calendar but only have viewing access to the other, or the calendars may belong to different account types. Some organizations also apply different policies to primary, shared, or group calendars. Check the calendar’s owner and account, then ask its owner or your administrator to adjust access if necessary.
