Change Who Can View an Outlook Calendar

To change who can view an Outlook calendar, open its sharing or permissions settings, select the person or group, and choose what they can see—or remove their access. The exact menu depends on whether you use new Outlook, classic Outlook for Windows, Outlook on the web, or a personal Outlook.com account.

How Outlook calendar access works

Calendar sharing is controlled separately from your email and from the invitations you send to meetings. Giving someone permission to view a calendar lets them see information in that calendar according to the access level you select. It does not automatically give them permission to read your inbox, change your account settings, or manage every calendar you own.

Outlook’s available sharing features depend on the account behind the app. Work and school accounts commonly use Microsoft 365 or Exchange, where calendar sharing is managed within the organization. Outlook.com accounts have consumer sharing options, which may look different. An organization can also restrict sharing, so a control that appears in one account may be missing in another.

Be precise about which calendar you are changing. Many people have a primary calendar plus additional calendars, such as a project calendar or a calendar they have added from another account. Changing the primary calendar’s permissions does not necessarily change the permissions of those other calendars.

Change permissions in new Outlook for Windows

In new Outlook for Windows, the calendar’s sharing controls are generally available from the calendar list. The names and placement of controls can change as Microsoft updates Outlook, but these steps are a useful starting point:

Open Calendar in Outlook.
In the calendar list, find the calendar you own and open its context menu, usually by right-clicking its name.
Select Sharing and permissions.
Find the person whose access you want to change. Select their current permission or open the relevant menu, then choose the access level you want.
To stop sharing with that person, use the remove or delete option beside their entry, then confirm if Outlook asks.

To share with someone new, use the calendar’s sharing option, enter their name or email address, select a permission level, and send the invitation. Check the calendar’s name before sending: a sharing invitation for a secondary calendar will not grant access to your primary calendar unless you select that one.

Change permissions in classic Outlook for Windows

Classic Outlook has a separate permissions view. Open Calendar, then use the calendar list to right-click the calendar you own and choose Properties or Sharing Permissions, depending on the Outlook build. In the calendar’s properties window, select the Permissions tab. You can select a person already listed and change their permission level, or add a person if the option is available.

For the primary calendar, another route in many classic Outlook versions is to select the calendar and go to Home > Share Calendar to send a sharing invitation. That invitation flow is useful for granting access; the calendar’s Permissions tab is often the clearer place to review or adjust entries already on the list. To remove access, select the person in the permissions list and choose Remove, then apply the change.

Classic Outlook may show more permission levels than new Outlook. Some are designed for assistants or colleagues who need to edit items, not merely view them. If you are unsure, use the least powerful level that meets the person’s needs. If the calendar belongs to a work account and you cannot change its permissions, your organization may control the setting.

Outlook on the web and Outlook for Mac

In Outlook on the web, open Calendar, select the calendar you own, and use Share or the calendar’s context menu to open its sharing options. Add a person or select an existing entry to adjust access, choose the appropriate permission, and send or save the change. The exact labels can vary between Outlook on the web and Outlook.com, and between account types.

Outlook for Mac also provides calendar sharing and permission controls, but the location and wording can vary by version and account. Look for sharing controls on the selected calendar or use Outlook’s calendar settings. If you cannot find a way to edit an existing person’s access, try Outlook on the web with the same work or school account; the web interface may expose the relevant sharing settings more clearly. Do not assume that removing an account from the Mac app revokes the other person’s permission—it only removes that account from your app.

Choose the right permission level

Before changing access, decide what the other person actually needs to do. Outlook may offer some or all of the following choices, depending on your account and app:

Availability only: The person can see when you are busy or free, without seeing ordinary event details. This is usually enough for scheduling.
Titles and locations: The person can see more context for appointments, such as their names and locations, but not necessarily all details.
All details: The person can view event information such as descriptions and attendees, subject to privacy settings and account behavior.
Editing access: The person can make changes to calendar items. Grant this only when they need to maintain the calendar with you.
Delegate access: Where offered, a delegate can have broader scheduling responsibilities, such as handling meeting requests. This is more powerful than ordinary viewing and should be assigned deliberately.

Permission names can differ between the simplified sharing menu and classic Outlook’s more detailed permission levels. For example, classic Outlook may show roles such as Reviewer or Editor, while newer interfaces may use plain-language descriptions. Compare what the level allows rather than relying only on the label. If the person needs to find a meeting time but not its subject, availability-only access is more appropriate than full details.

Change access, stop sharing, or check the result

To reduce someone’s access, edit their permission rather than creating a second sharing invitation with a different level. If you want them to have no calendar access, remove their entry from the sharing or permissions list. If Outlook offers a separate Stop sharing control, use it for the person or link you intend to revoke.

After changing permissions, allow time for the recipient’s calendar view to update. They may need to refresh Outlook or reopen the shared calendar. If access was granted through a sharing invitation, the recipient may also need to accept it before the calendar appears. When removing access, check the permissions list again and confirm you changed the correct person on the correct calendar. If the person still sees information after access is removed, ask them to refresh and verify whether they have another route to the calendar, such as access through a group or a different shared calendar.

Privacy limits and common misconceptions

Sharing a calendar is not the same as making it publicly searchable. In most ordinary sharing setups, you grant access to named people or people within an organization, subject to the account’s settings. Some accounts may offer a publish or public-link feature, but that is different from sharing with a specific colleague. Treat a public calendar link as information that could be forwarded or viewed by anyone who obtains it.

Marking an appointment Private is also not a replacement for limiting calendar access. Private items may hide their details from many people who can view the calendar, but behavior depends on the permission level and account configuration. A delegate with permission to view private items, or someone who is an attendee, may still have access to information. Do not put sensitive material in an event description on the assumption that the word Private will conceal it from every recipient.

Another common misconception is that sharing your calendar changes what meeting attendees can see. People invited to an event receive information needed to participate in that meeting; that is separate from ongoing permission to browse your calendar. Conversely, removing someone from calendar sharing does not retract an invitation they already received or erase information they previously copied.

When sharing controls are missing or do not work

If Outlook will not let you add or change a person, first check that you own the calendar or have permission to manage it. You may be viewing a calendar someone else shared with you, in which case its owner controls its sharing settings. Also confirm that you are using the correct account and calendar; a personal Outlook.com account and a work Microsoft 365 account can both be open in the same app.

For a work or school account, an administrator may restrict external sharing or set organization-wide calendar policies. A recipient outside your organization may be blocked even when sharing with colleagues works. Contact your IT support team if the option is disabled, an error says the action is restricted, or the permission change does not persist. Avoid sending a public calendar link as a workaround unless your organization permits it and the calendar contains only information suitable for public access.

Frequently Asked Questions

Can I let someone see when I am free without showing event names?
Yes. Choose the availability-only option, often described as viewing when you are busy or free. The precise label varies by Outlook version and account. Avoid a titles-and-locations or all-details permission if you want to keep appointment information private.

How do I stop sharing my Outlook calendar with one person?
Open the calendar’s sharing or permissions settings, select that person, and remove their permission or use the stop-sharing control. Make sure you are editing the calendar you own, then check the list afterward. Removing their entry does not cancel meeting invitations they already received.

Can someone edit my calendar if I only share it with them?
Not if you choose a view-only permission. Editing requires an edit-capable permission, and delegate access may provide additional scheduling powers. Review the selected level before sending the invitation, especially when using classic Outlook’s role-based permissions.

Why can’t I change calendar permissions?
You may not own the calendar, may be signed into the wrong account, or your organization may restrict sharing. Some permission changes are also unavailable in particular Outlook interfaces. Try the same account in Outlook on the web, and contact your organization’s administrator if the controls remain unavailable.

Does sharing my Outlook calendar share my email?
No. Calendar permissions control access to the selected calendar; they do not by themselves grant access to your inbox. However, event attendees receive meeting information through invitations, and a person with calendar access may see details according to the permission you grant.
