How to Share a Calendar in Outlook and Choose Access Levels

To share a calendar in Outlook, open Calendar, choose the calendar, select Share Calendar or Share, enter the person’s email address, and set their permission level. The exact controls vary between new Outlook, classic Outlook, Outlook on the web, and Mac, but the recipient usually must accept an invitation before the calendar appears in their view.

What You’ll Need

An Outlook account and a calendar stored in Microsoft 365, Exchange, or Outlook.com. Sharing may not be available for calendars stored only on your computer or in some IMAP/POP accounts.
The email address of each person who needs access. For work or school accounts, your organization may restrict sharing with people outside the organization.
A decision about what each person should be able to see or do. Choose the least access they need; viewing event details is different from being able to edit events.

Step-by-Step

Open the calendar you want to share. In Outlook, switch to Calendar using the calendar icon or app navigation. Check the calendar list, usually in the left pane, and select the specific calendar. If you have several calendars, confirm its name before sharing. Sharing your main calendar is not the same as sharing a separate project, family, or team calendar.
Open the sharing controls for your Outlook version. In new Outlook for Windows or Outlook on the web, select the calendar and choose Share or Share Calendar from the toolbar. If the button is not visible, right-click the calendar name and look for a sharing option. In classic Outlook for Windows, go to Calendar, select the calendar, then choose Home > Share Calendar. In Outlook for Mac, select the calendar and use the Share or Share Calendar control in the toolbar; the label and placement can vary by release. If you do not see a sharing control, check that this is an online account calendar rather than a local-only calendar.
Enter the recipient. Type the person’s email address in the sharing field or invitation’s To line. Select the correct suggested contact if Outlook offers one. For a work account, use the address associated with the recipient’s Microsoft 365 or Exchange account where possible. Add one person at a time if you need to assign different permissions to different people.
Choose an access level. The available choices depend on your Outlook version and account, but commonly include seeing only when you are busy, seeing titles and locations, seeing all event details, or editing the calendar. Use free/busy access when someone only needs to find an available time. Choose all details if they need to read event descriptions and locations. Grant edit access only to someone who should create, change, or delete calendar items. Classic Outlook may show permission levels such as Reviewer or Editor instead of the newer labels.
Check the invitation and send it. In new Outlook or Outlook on the web, review the selected permission beside the recipient before choosing Share. In classic Outlook, a sharing invitation opens; confirm the recipient and any details in the message, then select Send. If there is a message field, use it to explain why you are sharing the calendar or what the recipient should do next. The invitation is not a public link: it is directed to the people you specify.
Ask the recipient to accept and open the calendar. The recipient should look for the sharing invitation in their inbox, including Junk or Other if it is missing, and accept or add the calendar using the link or button in the message. After acceptance, the calendar should appear in their calendar list. In some Outlook versions they may need to switch to Calendar or refresh the app. If the recipient uses another email service, the calendar may open differently or may not support the same level of access.
Verify the permission and adjust it if needed. Return to the calendar’s sharing or permissions settings and confirm that the correct person has the intended access. If you need to change access, select that person and choose a different permission, then save or apply the change if prompted. To stop sharing, remove the person from the access list or select the remove option. Tell the recipient when you change access, especially if they rely on the calendar for work or scheduling.

Outlook calendar sharing normally keeps the calendar connected: changes can appear for the recipient without sending a new calendar file each time. The time it takes for a new share or permission change to show up can vary, so allow a little time before troubleshooting.

Common Mistakes

Sharing the wrong calendar. People often select their default calendar when they meant to share a separate calendar. Read the calendar name in the sharing dialog before sending the invitation.
Giving too much access. “Can view all details” exposes more than free/busy information, and edit access lets a person change calendar items. Match permissions to the task rather than choosing the broadest option for convenience.
Assuming the invitation completed the setup. Sending an invitation does not guarantee that the recipient has opened or added the calendar. Ask them to accept it and confirm that it appears in their calendar list.
Confusing calendar sharing with publishing. Sharing with named recipients is different from publishing a calendar to create a link that may be accessible to anyone who has it. Avoid publishing sensitive calendar information unless you understand the audience and your organization permits it.
Expecting identical controls in every Outlook app. New Outlook, classic Outlook, web, and Mac can use different labels and permission lists. Follow the instructions for the app you are actually using, and do not assume a missing button means the feature is unavailable to every version.

Tips

Use separate calendars for different audiences. For example, keep personal appointments on a private calendar and share a work-project calendar with colleagues. That makes it easier to grant access without exposing unrelated events.
Start with the minimum permission. Give someone free/busy access if they only schedule meetings with you. If they later need details or editing rights, update their permission rather than granting broad access in advance.
Review private events and descriptions. Calendar permissions may reveal event information, depending on the level selected and how an event is marked. Do not put confidential information in an event description unless the people with access are meant to see it.
Use delegate access only when appropriate. An assistant who needs to manage meeting requests may need delegate permissions, which are more involved than ordinary view or edit access. Set this up through the relevant Outlook or Exchange permissions and follow your organization’s guidance.
Keep access current. Remove former project members or other people who no longer need the calendar. For a work account, coordinate with the calendar owner or administrator if policy or account changes affect access.

Troubleshooting

I cannot find Share Calendar. Confirm that you selected a calendar in Calendar view, not an email or a folder. Try right-clicking the calendar name, checking the toolbar, or opening Outlook on the web with the same account. A calendar stored only on the computer, a non-Exchange account, or an account managed under restrictive organizational settings may not support sharing. In a work or school environment, ask your Microsoft 365 administrator whether sharing is disabled.

The recipient did not get the invitation. Check that you entered the correct address and that Outlook did not choose a similarly named contact. Ask the recipient to check Junk, spam, and any focused or other inbox tab. If necessary, remove the incorrect entry and send a new invitation. Some organizations block sharing invitations across their boundaries, so an administrator may need to confirm whether external sharing is allowed.

The recipient accepted, but the calendar is missing. Have them open Calendar and check the list of shared or additional calendars; the exact group name differs by Outlook version. They can try refreshing Outlook, closing and reopening the app, or signing in to Outlook on the web with the account that received the invitation. Make sure they accepted while signed in to that same account. If access was just granted, wait briefly and check again.

The recipient sees only busy times or cannot edit. Reopen the sharing or permissions list and inspect that person’s current access level. The invitation may have been sent with a limited setting, or an organization’s policy may restrict the available permissions. Change the level if you are authorized to do so, apply or resend the change if Outlook prompts, and ask the recipient to refresh. If the calendar is shared with a group, check whether the person’s access comes from the group rather than an individual share.

A permission change or removal does not seem to take effect. Confirm that you changed access on the correct calendar and selected the correct recipient. Allow time for the update to sync, then have the recipient refresh or reopen Outlook. If they still have access after removal, check for another share, group membership, or delegated permission that grants access separately. Contact your administrator if you cannot see or change the relevant permissions.

Frequently Asked Questions

Can I share an Outlook calendar with someone who does not use Outlook?
Sometimes. A person may be able to accept an invitation using another email address, but the viewing experience and supported permissions depend on their service and your account’s sharing rules. For reliable access, share with the email address tied to their Microsoft account or work account when available.

Can I share a calendar without letting someone edit it?
Yes. Choose a view-only permission, such as free/busy, titles and locations, or all details. The exact options differ by Outlook version. Avoid Editor or Can edit if the person should only view information.

Will the recipient see all my past and future events?
What they can see depends on the permission, calendar settings, and any event marked private. A view permission can expose details beyond just upcoming availability. Check the access level and review sensitive entries before sharing; do not assume that sharing reveals only future events.

Can I share only one event instead of my whole calendar?
Yes. If the recipient needs information about just one appointment, open that event and invite them or forward the meeting details rather than sharing the calendar. For a meeting, adding them as an attendee may send updates and let them respond, so use that only if they should participate.

How do I stop sharing my Outlook calendar?
Open the calendar’s sharing or permissions settings, find the person, and remove their access or change it to a more limited level. If access continues, check whether they also receive it through a group, a delegate role, or another shared calendar.

Why are some sharing options unavailable?
Your account type, Outlook version, organization policy, or the calendar’s storage location can limit sharing. Update Outlook if appropriate, try the web app, and ask your administrator about external sharing or permission restrictions. Do not publish the calendar publicly as a workaround for a policy restriction.
