How to Share a Calendar in Microsoft Outlook

To share a calendar in Microsoft Outlook, open Calendar, select Share or Share Calendar, choose the calendar and recipient, set an access level, and send the invitation. The recipient generally needs to accept the invitation to view the shared calendar. Before you begin, confirm you are sharing the right calendar and decide whether the other person needs to see availability only, event details, or make changes.

The exact buttons vary between new Outlook, classic Outlook for Windows, Outlook on the web, and Outlook for Mac. The steps below cover the common Microsoft 365 versions. Sharing works best with a Microsoft Exchange or Microsoft 365 work or school account; Outlook.com calendars can also be shared, while calendars from some other email providers or stored only on a device may not offer the same options.

What You’ll Need

An Outlook account and access to the calendar you want to share. You may need permission from your organization to share it.
The recipient’s email address. For the smoothest results, use the address associated with their Microsoft 365 or Outlook account.
A decision about the permission they need: availability, event details, or permission to edit.
A current Outlook app or access to Outlook on the web. The names and positions of buttons can differ by version.

Step-by-Step

Open the calendar you intend to share. In Outlook, select the Calendar icon from the app navigation, usually on the left. If you have several calendars, look in the calendar list and identify the one to share. Your primary calendar is not necessarily the only one listed: you might also have a team, project, or separately created calendar. Select the calendar or make a note of its name before opening the sharing controls.
Find the sharing command for your Outlook version. In new Outlook for Windows, open Calendar and select Share on the toolbar; if prompted, choose the calendar. In classic Outlook for Windows, select the calendar, open the Home tab, and choose Share Calendar. In Outlook on the web, open Calendar and select Share in the toolbar or next to the calendar name. In Outlook for Mac, select the calendar and look for Share Calendar or Share in the calendar toolbar. If the command is missing, check that the selected calendar is hosted by an account that supports sharing.
Enter the person or people to invite. Type an email address in the recipient field. Choose the matching contact suggestion if Outlook displays one, then add other recipients if needed. Sharing with a small group is often easier to manage when you send individual invitations, because you can give each person a different access level. Check spelling carefully; an invitation sent to the wrong address could disclose calendar information.
Choose an access level deliberately. The exact labels vary, but common choices include viewing only when you are busy, viewing titles and locations, viewing all event details, or editing the calendar. Busy-only access is suitable for scheduling without disclosing what an appointment is about. Full-detail viewing can reveal meeting names, locations, notes, and other information in events. Editing allows the recipient to change calendar items, so use it only when they need to maintain the calendar. Some classic Outlook setups show permission roles such as Reviewer or Editor instead of the newer wording.
Send the sharing invitation. Review the calendar name, recipient address, and permission level, then select Share or Send. Outlook sends an email invitation. The person may need to select Accept or Add calendar in that message before the calendar appears in their calendar list. Let them know which calendar you shared if you manage several calendars with similar names.
Check that the invitation was sent and accepted. Look for a confirmation or sent invitation in Outlook. Ask the recipient to check their inbox and junk or spam folder, and to accept the invitation using the account that was invited. After accepting, the shared calendar may appear under a heading such as Shared with me, Other calendars, or People’s calendars; the label depends on the app. They may need to select its checkbox to display it alongside their own calendar.
Change or remove access if needs change. In new Outlook or Outlook on the web, select the calendar’s sharing or permissions option; you can usually find it by selecting or right-clicking the calendar name. In classic Outlook for Windows, select the calendar and go to Home > Calendar Permissions. Choose the person’s entry to adjust their permission, or remove their access if they no longer need it. The recipient may retain information they already saw or copied, so removing access cannot undo prior disclosure.
Check the result with the recipient. Ask them to open the shared calendar and confirm that the intended events and level of detail are visible. If they can see the calendar but not the event information you expected, review the permission level and whether individual events are marked private. If they cannot see the calendar at all, have them accept the invitation while signed in to the invited account and refresh Outlook.

Common Mistakes

Sharing the wrong calendar. A person can have a primary calendar and several additional calendars. Verify the selected calendar’s name before sending the invite; sharing one calendar does not automatically share all of them.
Giving more access than necessary. Choosing full details or edit access for convenience can expose sensitive appointment information or allow unwanted changes. Start with the least access that will work and raise it only if the recipient needs more.
Assuming the invite itself adds the calendar. In many cases the recipient must accept the invitation. Sending it does not guarantee they have opened or added the calendar.
Inviting an address the recipient does not use. They may open Outlook under a different work, school, or personal account and then see an access error. Confirm which address they will use to sign in.
Confusing a live shared calendar with a calendar file. An emailed .ics file is usually a snapshot or subscription, not the same as granting a person permission to view or edit your live Outlook calendar. Use the sharing invitation when you want ongoing access with managed permissions.

Tips

Use the least-privilege approach. For basic coordination, busy-only visibility may be enough. Share event titles or full details only when they are genuinely useful to the recipient.
Keep private appointments in mind. An event marked private may hide its details from someone who otherwise has permission to view your calendar. If the recipient needs information about a particular event, consider whether you should change that event’s privacy setting rather than granting broader access to everything.
Explain what the recipient should expect. Include the calendar name and purpose in a short message, and ask them to accept the Outlook invitation. This is especially helpful when sharing a calendar with several similar names.
Review access periodically. Remove former project members or people who no longer need access. For a work or school account, an administrator may manage sharing policies or group access, so personal settings might not be the only control.
Use a published link cautiously. Publishing a calendar to the internet is different from inviting a named person and may make calendar information accessible to anyone who obtains the link. Prefer direct sharing for ordinary collaboration and follow your organization’s privacy rules.

Troubleshooting

The Share button is missing or disabled: Confirm that you selected a calendar rather than Mail or another app. Some calendars connected through IMAP, POP, or another provider are not hosted in Exchange and cannot use Outlook’s standard calendar-permission feature. Your organization may also block external or all calendar sharing. Try Outlook on the web with the same account; if the command is still unavailable, ask your Microsoft 365 administrator whether sharing is allowed.

The recipient did not receive the invitation: Verify the address and resend the invitation if needed. Ask the recipient to check junk mail and any quarantine folder managed by their organization. If the invite went to an external address, their mail system may have filtered it. Try sharing with the exact address they use for Outlook, and ask an administrator about external-sharing restrictions if delivery continues to fail.

The recipient accepted but cannot find the calendar: Make sure they are signed in to the account that received the invitation. Ask them to check Shared with me or Other calendars, expand the relevant section, and select the calendar to display it. Closing and reopening Outlook or refreshing the web page can help. If the invitation was forwarded, have the intended recipient request a new invitation directly; forwarding does not necessarily grant access.

They can see the calendar but not the details: Review the permission you assigned and check whether specific events are marked private. Busy-only access intentionally hides event subjects and details. If the recipient needs more information, raise their permission only as far as necessary. Some changes can take time to appear, particularly when the recipient uses an older Outlook app or a different device.

You cannot edit the calendar or change permissions: Check that you are the calendar owner or have been granted rights to manage sharing. For a work or school calendar, an administrator or calendar owner may need to make the change. In classic Outlook, use Home > Calendar Permissions to review entries; in newer versions, use the calendar’s sharing or permissions menu. If you recently changed a permission, allow time for the update to sync and ask the recipient to refresh.

Frequently Asked Questions

Can I share an Outlook calendar with someone outside my organization?
Often, yes, if your account and organization’s settings allow external sharing. Enter the person’s email address and choose an appropriate permission. If Outlook blocks the request or the option is unavailable, contact your Microsoft 365 administrator.

Can someone edit my calendar after I share it?
Only if you grant an edit-level permission, and the available options depend on the account and Outlook version. Choose a view-only permission when the person only needs to see your schedule. Review who has edit access from the calendar’s sharing or permissions settings.

Will the recipient see every appointment?
Not necessarily. What they can see depends on the permission level, whether an event is marked private, and which calendar you shared. Busy-only access shows availability rather than full details, and private events can remain hidden even when other events are visible.

Can I share just one event instead of my whole calendar?
Yes. Invite the person to that event by adding them as an attendee, or forward the event if appropriate. Sharing an individual event is often better when someone needs one meeting’s details but should not have ongoing access to your calendar.

How do I stop sharing my calendar?
Open the calendar’s sharing or permissions settings, select the recipient, and remove their permission. In classic Outlook for Windows, select the calendar and use Home > Calendar Permissions. Removing access stops future viewing through that permission, but it cannot retrieve details the person already viewed or saved.

Does sharing a calendar also share my email?
No. Calendar sharing grants access to the calendar at the permission level you choose; it does not by itself grant access to your Inbox or email messages. Check each app’s permissions separately if you are configuring broader delegation.
