How to Share a Calendar in Outlook and Set Permissions

To share an Outlook calendar, open Calendar, choose Share Calendar, select the calendar and recipient, set what they can see or do, then send the invitation. The exact button names vary between classic Outlook, new Outlook, Outlook for Mac, and Outlook on the web, but the key choice is the permission level: decide whether someone needs availability only, full event details, or editing access.

What You’ll Need

An Outlook calendar connected to a Microsoft 365 or Exchange account, or an Outlook.com account that supports calendar sharing. Calendars stored only in a local file or a non-Exchange account may not offer the same sharing options.
The recipient’s email address. For a work or school calendar, sharing may be limited by your organization’s Microsoft 365 administrator.
A clear idea of what access the recipient needs. Choose the least access that will let them do the job, especially if event details include private or sensitive information.

Step-by-Step

Open the calendar you intend to share. In Outlook for Windows, select the Calendar icon. If you have more than one account or calendar, check the calendar list and identify the correct one before sharing. You might see a personal calendar and a work calendar with similar names. Sharing the wrong one can expose unrelated appointments or send an invitation from the wrong account.
Start the sharing command for your Outlook version. In classic Outlook for Microsoft 365 on Windows, select the calendar, then go to Home > Share Calendar. In new Outlook for Windows, open Calendar and select Share Calendar from the toolbar; choose the calendar if Outlook asks. In Outlook on the web, open Calendar and select Share or Share calendar, then select the calendar. In Outlook for Mac, open Calendar, select the calendar you want to share, and choose Share Calendar or Sharing Permissions, depending on the version. If the command is not visible, check the calendar’s context menu or the toolbar’s more-options menu.
Enter the recipient. Type the person’s email address in the sharing or invitation field. If Outlook offers a directory list, select the correct person from your organization’s address book; do not rely on a similar display name alone. You can usually add more than one recipient, but sharing separately makes it easier to give each person an appropriate permission level. For an external recipient, use the address they can access and check that your organization permits external sharing.
Choose the permission level carefully. Common choices include viewing only when you are busy, viewing titles and locations, viewing all event details, and editing the calendar. Availability-only access is suitable when someone just needs to schedule around you. Full details may show subjects, locations, and other information recorded in events. Editing access lets the recipient make changes, so reserve it for people who need to maintain the calendar. Some accounts also offer delegate access, which can include additional scheduling responsibilities; do not select it unless that is what you intend.
Review what will be shared before sending. Confirm the calendar name, email address, and permission setting. Consider whether private appointments or sensitive event descriptions are on the calendar. A general calendar permission may reveal details for more events than the recipient needs. If only certain appointments should be visible, consider creating a separate calendar for shared work rather than granting broad access to a personal one.
Send the sharing invitation. In new Outlook, Outlook on the web, or Outlook for Mac, select Share or the equivalent confirmation button. In classic Outlook for Windows, the sharing invitation opens as an email: verify the recipient and detail level, then select Send. The recipient may need to accept the invitation or use its link before the calendar appears in their Outlook. Sending the invitation does not necessarily add the calendar automatically on every version or device.
Ask the recipient to check the invitation and open the calendar. They should look in their inbox and, if it is missing, their junk or quarantine folder. Depending on their Outlook version, accepting may add the calendar under Shared calendars or open it alongside their own. If they use a different email address for Outlook than the one you invited, have them confirm which account they are signed in to before trying again.
Change or remove access when needed. In classic Outlook for Windows, select the calendar and use Home > Calendar Permissions to review or remove a person’s permission. In new Outlook or Outlook on the web, open the calendar’s sharing options or context menu and look for Sharing and permissions. On Mac, open the calendar’s sharing permissions. Select the person’s entry to adjust access or remove them, then save or confirm if prompted. Removing permission stops future access, although it cannot undo information the person has already seen, copied, or exported.

Common Mistakes

Choosing the wrong calendar. Outlook may show several calendars with similar names, especially when you have multiple accounts. Confirm the account and calendar name in the sharing window, not just the name in the left-hand list. If you discover the error after sending, remove the unintended permission and then share the correct calendar.

Giving more access than necessary. Full details and editing permissions are not the same as availability-only access. A recipient who only needs to arrange a meeting usually does not need to edit your events. Remember that event descriptions can contain private notes, meeting links, or information about other people.

Assuming the invitation automatically adds the calendar. The recipient may have to accept the invitation, click its link, or add the shared calendar in their own Outlook. If they cannot see it immediately, confirm acceptance and the account they are using before resending.

Sharing with an address that is not the recipient’s Outlook sign-in. A person may receive an invitation at one address but use another account in Outlook. This can lead to access prompts or a calendar that appears to be missing. Ask them to open the invitation while signed in to the invited account, or resend it to the account they actually use.

Tips

Use availability-only sharing for scheduling. If colleagues only need to find an open meeting time, share when you are busy rather than exposing subjects and locations. This is often enough for meeting coordination.
Give edit access only to a calendar maintainer. Editing can change or delete events, so it is best suited to a trusted assistant or teammate responsible for keeping that calendar current. If Outlook offers separate delegate settings, read their description before granting them.
Use a dedicated shared calendar for group plans. A project, rota, or household calendar can keep shared events separate from personal appointments. Add relevant events there instead of granting broad access to a personal calendar. Check which calendar is selected when you create a new event.
Review permissions periodically. Remove access when a project ends or someone changes roles. If a person still needs access but their responsibilities have changed, lower or raise their permission rather than leaving an outdated setting in place.
Expect small differences on Mac and the web. Outlook for Mac and Outlook on the web use similar sharing concepts, but the toolbar labels and location of permission controls can differ from classic Outlook for Windows. Use the calendar’s sharing menu and verify the permission before confirming.
Keep private appointments private where appropriate. Marking an individual event private can limit what some calendar viewers see, but how private details are handled can depend on permission level and delegate settings. Do not treat the Private label as a replacement for choosing the right overall sharing permissions.

Troubleshooting

The Share Calendar option is missing or disabled. Confirm that you selected a calendar backed by Microsoft 365, Exchange, or Outlook.com, rather than a local or unsupported account calendar. In work or school Outlook, your administrator may have blocked sharing, especially with people outside the organization. Try Outlook on the web if your organization allows it; if the option is still unavailable, contact your Microsoft 365 administrator and ask whether calendar sharing is enabled for your account.

The recipient does not receive the invitation. Check the spelling of the email address and confirm it is the address they use to access Outlook. Ask them to search their inbox, junk folder, and any company quarantine. If there is no invitation, remove an incorrect entry if necessary and send a fresh one. Avoid repeatedly sending invitations without checking the address, since that can create confusion about which permission is current.

The recipient sees a permission error or cannot open the calendar. First confirm that they accepted the invitation and are signed in with the invited account. If the recipient is outside your organization, external sharing restrictions may prevent access even when Outlook lets you enter their address. Check with your administrator rather than trying to bypass the restriction. For an internal recipient, remove and re-add the permission only after verifying the correct account and calendar.

The calendar appears, but details or changes are missing. Confirm the permission level you granted. An availability-only setting intentionally hides event details, and view-only access does not let the recipient update events. Changes may also take time to appear or require the recipient to refresh Outlook. If the recipient should edit events, update their permission to an appropriate editing level and have them reopen or refresh the calendar.

You shared the wrong calendar or person. Return to the calendar’s sharing permissions, remove the unintended recipient or access entry, and verify the intended calendar before sharing again. If sensitive details were exposed, treat that as an information-sharing incident and follow your workplace or organization’s reporting process. Revoking access prevents future viewing but cannot retract information already seen.

Frequently Asked Questions

Can I share an Outlook calendar with someone outside my organization?
Sometimes. Outlook.com accounts may allow sharing with external recipients, but work or school Microsoft 365 organizations can restrict it. If the invitation fails or the external person cannot open the calendar, ask your administrator whether external calendar sharing is allowed.

Can I share only my free and busy times?
Yes. Choose a permission such as Can view when I’m busy or the equivalent availability-only option. The exact wording varies by Outlook version. This lets someone check when you are available without showing the full event details.

Can the other person edit my calendar?
Yes, if you grant an editing permission and the account supports it. Choose an edit level only for someone who should be able to change events. If they only need to schedule around you, use a viewing permission instead.

Does sharing a calendar give someone access to my email?
No. Calendar sharing grants access to the selected calendar according to its permission settings; it does not by itself grant access to your inbox. Delegate arrangements can involve additional scheduling capabilities, so review the options carefully before granting delegate access.

How do I stop sharing an Outlook calendar?
Open the calendar’s sharing or permissions settings, select the recipient, and remove their permission. The recipient should lose ongoing access, although previously viewed or saved information cannot be recalled. If your Outlook layout differs, look for Calendar Permissions in classic Outlook or Sharing and permissions in new Outlook or on the web.

Why can I share a calendar with one person but not another?
Your organization may apply different rules to internal and external recipients, or the recipient’s account may not support the requested sharing method. Check the email address, the permission options available for that account, and any administrator restrictions. Ask your Microsoft 365 administrator for help if the policy is unclear.
