How to Share a Calendar in Outlook by Email or Link

To share a calendar in Outlook, open Calendar, choose Share Calendar, add the person’s email address, set what they can see or change, and send the invitation. The recipient gets an email invitation to open the shared calendar; the exact buttons differ slightly between new Outlook, classic Outlook, Outlook on the web, and Outlook for Mac.

Sharing gives someone access to a calendar that can update as appointments change, rather than just sending a one-time list of events. Before sending, decide whether they need to see only when you are free, event details, or permission to edit. Check the calendar name too, especially if you have more than one.

What You’ll Need

An Outlook account and a calendar stored in a Microsoft 365, Exchange, or Outlook.com mailbox. A calendar stored only on your computer, such as a local PST calendar, may not support sharing invitations.
The recipient’s email address. Sharing works most smoothly when the address is associated with a Microsoft account or organization, though your account’s sharing policy may allow other addresses.
Outlook access on Windows, Mac, or the web, plus an internet connection. Your organization may restrict sharing outside the company.
A decision about the permission level. Calendar access can reveal private information, so share only the detail the other person needs.

Step-by-Step

Open the calendar you want to share. In Outlook, select the Calendar icon, usually in the navigation bar. If you have several calendars, select the one you intend to share from the calendar list. Check its name and any color label before continuing; sharing the wrong calendar can expose appointments you meant to keep private.
Find the sharing command. In new Outlook for Windows, select the calendar, then use Home > Share Calendar or the Share button on the Calendar toolbar, depending on the layout. In classic Outlook for Windows, select Calendar and choose Home > Share Calendar in the Share group. In Outlook on the web, open Calendar, select the calendar, and choose Share on the toolbar. Outlook for Mac also has a calendar sharing command from the Calendar toolbar or the calendar’s context menu; the wording and position can vary by release.
Select the calendar, if Outlook asks. Some versions open a sharing window with a calendar selector. Choose the specific calendar rather than assuming Outlook has selected the one currently displayed. If the command is unavailable or the calendar does not appear, it may be a local calendar or an account whose provider does not support online sharing.
Enter the recipient’s email address. Type the full address in the recipient field. If Outlook offers a contact suggestion, confirm that it is the intended person. Add one recipient at a time if you want to give different people different access levels. Avoid putting a group of people on an invitation with broad permissions unless everyone should receive the same access.
Choose the access level. Options vary by account and Outlook version, but commonly include seeing when you are busy, seeing titles and locations, seeing all event details, or editing the calendar. Choose the least access that meets the need. “Can view all details” is not the same as “Can edit”: the first lets the person read appointments, while the second can allow changes. If you are unsure, start with view-only access and increase it later if necessary.
Review the invitation and send it. In classic Outlook for Windows, the sharing dialog may let you add a message and select the detail level before sending. In new Outlook and Outlook on the web, confirm the recipient and permission in the share pane, then select Share or Send. Read the confirmation carefully; it should identify the calendar and the person who will receive access. The invitation is sent by email, but this is a calendar-sharing invitation, not simply a copy of your appointments.
Ask the recipient to accept the invitation. They should open the sharing email and select its accept or open-calendar option, then sign in with the account the invitation was sent to if prompted. The calendar may appear under shared calendars in their Outlook calendar list. If it does not show immediately, have them refresh Outlook or close and reopen Calendar.
Check the result and adjust permissions if needed. Ask the recipient to confirm that the calendar appears and that the level of detail is appropriate. To change or remove access, return to the sharing or permissions screen for that calendar, find the person, and select a different permission or remove them. Names of these commands differ: classic Outlook may use Calendar Properties > Permissions, while web and newer versions provide sharing or access controls from the calendar menu.

If you only need to send a copy of dates: use a calendar email or an .ics attachment rather than granting ongoing access. In classic Outlook for Windows, the calendar’s Home > E-mail Calendar command can send a date-range snapshot. A snapshot does not keep updating when you change an appointment, and an .ics file the recipient imports is also separate from live sharing.

Common Mistakes

Choosing the wrong calendar: Outlook may display several calendars together, but the sharing command applies to a particular calendar. Verify its name in the share window, not just the events currently visible on screen.

Giving more access than intended: “Can edit” is powerful and should be reserved for people who need to create, change, or manage events. View permissions can still disclose sensitive meeting subjects, locations, or notes. Pick a level based on the information the recipient genuinely needs.

Expecting an email copy to stay current: A calendar email, screenshot, or attached .ics file is not the same as sharing a live calendar. Later changes will not necessarily appear in a copy that was already sent. Use the sharing invitation for ongoing access.

Sending to an address the recipient does not use: The person may accept the invitation while signed in to a different account, then wonder why the calendar is missing. Send it to the address they use in Outlook and ask them to switch to that account if prompted.

Assuming a share invitation has been accepted: Sending the invitation does not always mean the recipient has opened it. Check that they accepted and look in their shared calendars list before sending another invitation.

Tips

Use busy-only access when the recipient just needs to schedule meetings without seeing event names or details.
Use a separate calendar for a team project or family schedule if you do not want to expose personal appointments on your main calendar. Share that calendar with only the relevant people.
Use view-only access for most recipients. Grant editing rights only when the person is expected to maintain the calendar, and remove access when their role changes.
Tell the recipient which email address you invited and whether they need to accept an invitation. This helps avoid confusion when they have multiple work or personal accounts.
For a meeting invitation, invite attendees to the individual event instead of sharing your entire calendar. Calendar sharing exposes access beyond one appointment.
Remember that private-event settings and shared-calendar permissions can interact differently depending on the Outlook version and organization policy. Do not rely on a private label as a substitute for limiting who can access the calendar.

Troubleshooting

The Share Calendar button is missing or disabled: Confirm that you are signed in to the account that owns the calendar, and that you selected a calendar rather than a mail folder. Local calendars and some third-party account types do not support Outlook’s sharing feature. If it is a work account, your Microsoft 365 administrator may have disabled sharing, especially with people outside your organization. Ask the administrator or try the account’s Outlook on the web calendar.

The invitation will not send: Check the spelling of the email address, your internet connection, and whether Outlook has finished syncing. Try entering the address manually rather than choosing an outdated contact suggestion. If external sharing is blocked, sending to a personal address may be rejected; use an approved organizational address or contact IT.

The recipient cannot find the shared calendar: Ask them to open the invitation while signed in to the exact address it was sent to and select the accept or add-calendar option. Then check the calendar list for a section such as Shared calendars or People’s calendars. In Outlook on the web, refreshing the page can help; in desktop Outlook, restarting the app or allowing time for synchronization may help. They should also check junk mail for the invitation.

The recipient sees only busy blocks or not enough details: Review the permission level on your side and raise it only if appropriate. The recipient may need to remove and re-add the calendar or refresh it before the new level appears. Some organizations limit what can be shared, so a permission option may not be available even if another Outlook account offers it.

The recipient cannot edit events: Confirm that you granted editing permission rather than a view-only level. If the setting is correct but changes still fail, check whether the recipient opened the shared calendar rather than a separate copy or imported .ics file. An imported calendar snapshot is not a live editable shared calendar.

You shared the wrong calendar or person: Return to that calendar’s permissions, remove the unintended recipient, and check the access list for anyone else who should not have access. If sensitive information was exposed, follow your organization’s reporting process. Removing access prevents future viewing through the share, but it cannot recall information the recipient has already seen or copied.

Frequently Asked Questions

Can I share an Outlook calendar with someone who does not use Outlook?
Sometimes. Whether an external email address can receive access depends on your Outlook account and organization’s sharing settings. The recipient may need a Microsoft account or may be able to open a link after verification. If live sharing is blocked, send a calendar snapshot or an .ics file instead, knowing it will not automatically update.

Does sharing a calendar send all my appointments by email?
No. The invitation grants access to the calendar at the permission level you select; it is not normally a message containing every event. What the person can see depends on that level and your account’s settings. A calendar email or exported file is a separate way to send a limited copy.

Can someone edit my calendar after I share it?
Only if you grant an editing permission and the account supports it. A view-only permission allows the person to see information but not manage your events. Review the permission label carefully before sending, and remove editing access when it is no longer needed.

How do I stop sharing my Outlook calendar?
Open the calendar’s sharing or permissions settings, select the person, and remove their access or change it to a more limited level. The menu path varies across Outlook versions. The change may take a short time to appear for the recipient, and it cannot undo copies or notes they already made.

What is the difference between sharing and emailing a calendar?
Sharing gives someone ongoing access that can reflect later changes, subject to their permission level. Emailing a calendar or sending an .ics file provides a snapshot or copy and does not reliably stay synchronized. Choose sharing for ongoing coordination and a copy for a one-time schedule.
