Share a Calendar in Outlook 365: Step-by-Step Guide

To share an Outlook 365 calendar, open Calendar, choose Share calendar, select the calendar and recipient, then assign a permission such as viewing details or editing. The recipient usually gets an email invitation and must accept it to add the shared calendar. You need an Outlook or Microsoft 365 account, and your organization’s settings must allow the type of sharing you want.

What You’ll Need

An Outlook account and access to the calendar you want to share. You can share calendars you own or have permission to manage; you cannot grant access beyond your own rights.
The recipient’s correct email address. For people in your organization, use the address associated with their Microsoft 365 account when possible.
A decision about what the recipient should be able to see or do. Choose the least access that meets the need, especially for work or personal calendars.
If you are sharing with someone outside your organization, permission from your Microsoft 365 administrator may be required. Some organizations block external sharing or limit what details can be exposed.

Step-by-Step

Open the calendar you want to share. In Outlook on the web, sign in to Microsoft 365 or Outlook, then select Calendar from the app navigation. In the new Outlook for Windows, select the Calendar icon in the left navigation. In classic Outlook for Windows, select the Calendar icon at the lower-left or in the navigation pane. If you have several calendars, identify the specific one by its name before continuing.
Open the sharing controls. In Outlook on the web or new Outlook, select Share calendar near the top of the calendar view. If the button is not visible, open the calendar list, right-click the calendar name, and look for Sharing and permissions or Share. In classic Outlook for Windows, select the calendar, open the Home tab, and select Share Calendar. Outlook for Mac has a Share Calendar command from the Calendar view; depending on the version, it may be on the toolbar or under the calendar’s context menu.
Choose the correct calendar. If Outlook asks which calendar to share, select the calendar you intend to provide access to. The main calendar is usually named Calendar, but users may have additional calendars for projects, teams, or personal events. Check the name carefully: sharing one calendar does not automatically share every calendar in your account.
Add the recipient. Type the person’s email address in the sharing box. Select the matching suggestion if Outlook offers one, then confirm the address is correct. You can often add more than one person, but setting access individually is safer when different people need different permissions. If the recipient does not appear in the directory, type their full email address rather than a display name.
Choose a permission level. For someone who only needs to coordinate availability, choose an option like Can view when I’m busy. To reveal event names and locations, choose Can view titles and locations if it is offered. Choose Can view all details only when the recipient needs the full event information. Can edit allows the person to make changes to the calendar, so reserve it for trusted collaborators who need to add, change, or remove events. The exact labels vary by Outlook version and account.
Send the invitation. Select Share or Send to issue the calendar invitation. In classic Outlook for Windows, the Share Calendar command may open a sharing invitation email; address it and select Send. If Outlook asks whether you want to send an update, confirm when you are granting or changing access. The invitation is separate from ordinary event invitations, so do not assume that forwarding a meeting will share the calendar.
Ask the recipient to accept and open the calendar. They should open the sharing email and select Accept or Add calendar, then check the shared calendar in their Outlook calendar list. They may need to refresh Outlook or switch to Calendar to see it. If the email is missing, ask them to check Junk or Spam and confirm that you used the right address. A shared calendar may appear under Shared calendars or People’s calendars, depending on the client.
Verify access and adjust it if needed. Ask the recipient to confirm that the calendar appears and that they can see only the level of detail you intended. If access is too broad or too limited, return to the sharing or permissions panel, change that person’s permission, and save or send the update. To revoke access, use the same panel and remove the person or choose the option to stop sharing. Removing access does not delete the calendar or its events.

For classic Outlook permissions: If the usual Share Calendar invitation does not offer the level you need, open the calendar’s Properties or Sharing Permissions dialog and use its Permissions tab. The permission roles can include Reviewer, which allows viewing, and Editor, which allows creating and changing items. More advanced roles and delegate access are different from basic calendar sharing. Delegate access can include managing meeting requests on your behalf, so do not select it simply to let someone see your schedule.

Common Mistakes

Granting more access than necessary. Can edit is not just a way to see more information; it lets the person change calendar items. Use a view-only permission unless editing is genuinely required.
Sharing the wrong calendar. A user may have multiple calendars with similar names. Check the calendar selected in the sharing panel, particularly before sharing a personal calendar or a calendar containing confidential appointments.
Assuming the invitation was accepted. Sending the share request does not guarantee the other person has added the calendar. Ask them to accept the message and check the calendar list in their Outlook account.
Expecting a shared calendar to work like a copied calendar. A shared calendar stays connected to its owner’s calendar. It is not a separate copy, and the recipient’s ability to make changes depends on the permission granted.
Using a meeting invitation to share the calendar. Inviting someone to one event gives access to that event, not to the rest of your calendar. Use the calendar-sharing controls for ongoing access.
Overlooking work-account restrictions. A company policy can prevent sharing with people outside the organization, even when Outlook shows a sharing option. Repeatedly resending the invite will not override an administrator’s restriction.

Tips

Match the permission to the task. Someone arranging a meeting may only need to see when you are busy. A close teammate may need event details, while an assistant who manages appointments may need edit or delegate rights. Decide based on the actual job, not convenience.
Review what event details reveal. Titles, locations, notes, and attendee information can contain sensitive material. If a calendar includes private appointments, keep sharing limited or consider maintaining a separate calendar for information that is appropriate to share.
Share with individual accounts where practical. A named person’s access is easier to review and remove than a broad link. Avoid forwarding an invitation to others, since access may be intended for the original recipient only.
Use separate calendars for different audiences. For example, keep a team project calendar distinct from a personal calendar. This makes it easier to share relevant events without exposing unrelated appointments.
Check permissions periodically. When a project ends or someone changes roles, remove access they no longer need. Calendar permissions can remain in place long after the original reason for sharing has passed.
Know that interface labels can differ. Outlook on the web, new Outlook, classic Outlook for Windows, and Outlook for Mac do not always place sharing commands in the same location. Look for Share calendar or Sharing and permissions, and make sure you are signed in to the account that owns the calendar.

Troubleshooting

The Share calendar button is missing. Confirm that you are in Calendar rather than Mail and that the calendar is one you own or are allowed to manage. Try selecting the calendar name in the calendar list, then use its right-click or context menu. In classic Outlook, select the calendar first and check the Home tab. If your account is a work or school account and sharing controls remain unavailable, contact your Microsoft 365 administrator.

The recipient did not receive the invitation. Check the spelling of the email address and whether the message was sent from the account that owns the calendar. Ask the recipient to search Inbox, Junk, and Spam for the sharing invitation. If the address was wrong, remove the mistaken permission if it was created, then share with the correct address. Resend only after confirming the recipient and permission.

The recipient accepted, but the calendar is not visible. Ask them to open Calendar and inspect Shared calendars or People’s calendars. They can refresh the page, close and reopen Outlook, or sign out and back in to the correct account. In some clients, the calendar is added only after they select the acceptance link in the invitation. If they use several Microsoft accounts, verify that they accepted while signed in to the account you shared with.

The recipient sees busy blocks but not event details. This usually means the permission is set to show availability only. Change the permission to a detail-view option if it is appropriate, then send or save the update. The recipient may need to reopen or refresh the shared calendar. If the event itself is marked Private, its details may remain hidden even when the person has broader calendar access.

External sharing is blocked or an error appears. Your organization may prohibit external calendar sharing, or allow it only at a limited detail level. Ask your Microsoft 365 administrator whether external sharing is enabled and which permissions are permitted. Do not try to bypass the policy by publishing a public calendar link: a link that anyone can use may expose information beyond the intended recipient.

The recipient can see the calendar but cannot change events. That is expected with view-only access. If they need to update events, change their permission to Can edit or the equivalent role available in your Outlook version. If they need to manage meeting requests on your behalf, investigate delegate access separately and grant it only after confirming what that role allows in your account.

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 your account type and your organization’s sharing rules. They may need to use a Microsoft account or a supported calendar app. Ask your administrator if external sharing is restricted.

Can I share a calendar without showing event details?
Yes. Choose a permission such as Can view when I’m busy, where available. This lets the recipient check availability without seeing normal event titles and details. Events marked Private can have additional limits, so check the result before relying on it.

Can the other person add or edit appointments?
Only if you grant an editing permission, such as Can edit or the equivalent Editor role. View-only sharing does not let them change your calendar. Give editing access only to people you trust, because it may allow changes to existing items as well as new ones.

How do I stop sharing my calendar?
Open the calendar’s Share or Sharing and permissions panel, find the person, and remove their access or select Stop sharing. The person may need to remove the calendar from their own list as well. Revoking permission does not erase events from your calendar.

Is sharing the same as publishing a calendar?
No. Sharing normally grants access to specific people through Outlook permissions. Publishing can create a link or feed that may be accessible to a wider audience, depending on its settings. Use person-by-person sharing for private calendars and follow your organization’s rules before publishing anything.
