Share Outlook Calendar URL: Links and Access

To share an Outlook calendar URL, open Outlook on the web, go to Settings > Calendar > Shared calendars, choose the calendar and its permission level under Publish a calendar, then select Publish. Outlook provides an HTML link for viewing the calendar in a browser and an ICS link that someone can use to subscribe; use ordinary calendar sharing instead when you want to grant access to specific people.

What an Outlook calendar URL does

“Share my Outlook calendar URL” can mean two different things. You might want to send a link that lets someone view a published calendar, or you might want to share access with named people so the calendar appears in their Outlook. Those options work differently, so choose based on who needs access and whether the calendar should update for them.

Publishing creates links that can be opened or subscribed to by people who have them. It is useful for a public schedule, such as event dates or office hours, but it is not the same as inviting a colleague to a private calendar. A recipient with an ICS subscription can see updates as the calendar changes, although the timing of refreshes depends on the recipient’s calendar app.

Direct sharing is usually better for coworkers, family members, or a small group. You grant access to particular accounts and can choose what they are allowed to see or do. Depending on your Outlook account and organization’s settings, recipients may need to sign in or accept a sharing invitation.

Choose between publishing and direct sharing

Before you create a link, decide what access you actually need to provide:

Publish an HTML link when recipients should open a browser page to view the calendar. It is convenient for people who do not want to subscribe in a calendar app.
Publish an ICS link when recipients want the calendar to appear alongside their own calendars. This is generally a subscription feed, not a way to edit your calendar.
Share with specific people when access should be limited to named recipients, or when you want to give someone editing or delegate permissions if your account supports them.
Send an individual event invitation when a person only needs details about one appointment. That avoids exposing the rest of your calendar.

A published link is easy to forward, so it should not be treated like a private invitation. If the calendar contains personal appointments, use specific-person sharing and the least revealing permission that will do the job.

Publish a calendar and copy its URL

In Outlook on the web, including the web version used with many Microsoft 365 accounts, follow these steps. The exact wording or available choices can vary with account type and organization policy.

Open Outlook in a browser and switch to Calendar.
Select Settings, then open Calendar > Shared calendars.
Find Publish a calendar. Select the calendar you want to share and choose a permission level from the available options.
Select Publish. Outlook displays an HTML link and an ICS link.
Copy the link that matches the recipient’s needs and send it through an appropriate channel.

The HTML option is intended for browser viewing. The ICS option is intended for a calendar app to subscribe to or use as an internet calendar. Keep the complete URL intact: deleting characters or changing its encoding can make it unusable. If you cannot see Publish a calendar, check whether you are signed into the right account; publishing may not be available for every account or may be disabled by an administrator.

Outlook for Windows and Outlook for Mac can have different controls depending on whether you use the new or classic app and which account is connected. If the publishing controls are missing in the desktop app, use Outlook on the web for that account. Do not assume that a sharing invitation generated from the desktop app is the same thing as a published HTML or ICS URL.

Share directly with named people

For a private calendar, use Outlook’s sharing feature rather than publishing a URL. In Outlook on the web or new Outlook for Windows, open Calendar, select the calendar you own, and choose Share. Enter the person’s email address and select the permission offered in the sharing panel before sending the invitation. The recipient may need to accept it, and their access is associated with their account rather than being granted to anyone who receives a forwarded link.

In classic Outlook for Windows, the calendar sharing command is generally on the Calendar ribbon under Home > Share Calendar. Choose the calendar, address the sharing invitation, and set the permission options shown for your account. On a Mac, available sharing controls depend on the Outlook version and account; Outlook on the web is a practical route if the desktop interface does not offer the option you need.

Permission names and choices can vary. A view-only permission lets someone see calendar information without changing your appointments; an edit permission lets them make changes. Some Microsoft 365 or Exchange accounts also support delegate arrangements, which can include managing meeting requests. Do not give edit or delegate access just to let someone check when you are free.

What recipients can do with an ICS link

An ICS URL is not a normal document download. When a recipient subscribes to it, their calendar app can retrieve calendar data from the link and refresh it later. This is different from importing a downloaded .ics file once: an import is typically a copy of the events at that moment, while a subscription is designed to receive later updates. The recipient’s app controls how often it checks for changes, so updates may not appear immediately.

In Outlook, recipients can look for an option to add or subscribe to a calendar from the web and paste the ICS URL. Labels and locations differ between Outlook on the web, new Outlook, classic Outlook, and other calendar apps. If someone only needs to view the schedule occasionally, sending the HTML link may be simpler. If they need the events alongside their own appointments, an ICS subscription is usually the more useful choice.

Do not promise that an ICS subscription lets the recipient edit your original events. A published feed is for viewing; changes should be made by the calendar owner or by people who have separately been granted editing access.

Permissions, privacy, and revoking access

Choose a permission level that reveals no more than necessary. Depending on the account, publishing choices may range from showing availability to showing more appointment details. Even a setting intended to show limited information should be checked against the actual calendar and account options before you send the link. Calendar entries can reveal routines, locations, travel, or sensitive personal details.

Anyone who obtains a published URL may be able to use it, and recipients can forward it. Treat the URL as a secret access link, not as a password-protected invitation. Share it only with the intended audience, avoid posting it in a public place unless that is your goal, and review what the calendar exposes before publishing.

If a published link should no longer work, return to Settings > Calendar > Shared calendars and use the available unpublish control for that calendar. If you shared with named people, change or remove their permission in the sharing settings. Removing a person’s direct access does not automatically retract copies of information they already viewed, exported, or received in invitations.

Common problems and practical fixes

No Publish a calendar option: Confirm the correct account is open and try Outlook on the web. A work or school administrator may restrict external sharing or publishing, and some account types do not offer the same features.
The recipient cannot open the link: Check that you copied the full HTML or ICS link, did not accidentally copy a shortened or incomplete version, and have not unpublished the calendar. Ask whether the recipient is opening the correct link type.
The calendar appears empty or incomplete: Review the publication permission and confirm you selected the intended calendar. A setting that limits visible information may not show event details. Also check the calendar’s date range and whether the events are actually on that calendar.
Updates are delayed: An ICS subscriber’s app may refresh on its own schedule. A published feed should not be treated as an instant notification system; send a separate message for time-sensitive changes.
The recipient wants to edit events: An ICS subscription is not the solution. Share the calendar directly and grant an appropriate edit permission only if the account and your privacy needs allow it.

If the recipient is inside your organization, your Microsoft 365 administrator may control which sharing options are allowed. If the recipient is outside it, external-sharing rules may apply. In either case, a missing option can reflect policy rather than a problem with your calendar.

Alternatives to sharing a calendar URL

A calendar URL is not always the best way to communicate a schedule. For one appointment, send an invitation so the recipient can respond and receive updates about that event. For a small team that needs to coordinate or edit a common schedule, a shared calendar with named users is usually easier to administer than a broadly accessible published feed.

If you only need to show availability, use a permission that hides event details where available, or share selected free/busy information through the tools your account provides. For a public list of events, a published calendar can be convenient, but consider whether a public webpage or event service is more suitable for your audience. Whichever method you choose, make sure the people who need access can use it without exposing unrelated appointments.

Frequently Asked Questions

How do I find my Outlook calendar URL?
In Outlook on the web, open Settings > Calendar > Shared calendars. Under Publish a calendar, select the calendar and permission, then select Publish to display its HTML and ICS links.

What is the difference between the Outlook HTML and ICS links?
The HTML link is for viewing the published calendar in a browser. The ICS link is for adding or subscribing to it in a calendar app. Neither should be confused with a direct editing permission.

Can I share an Outlook calendar URL privately?
A published URL can be forwarded, so it is not restricted to named recipients in the same way as direct sharing. For private access, share the calendar with specific people and set permissions for their accounts.

Does an Outlook ICS link update automatically?
An ICS subscription is designed to refresh as the calendar changes, but the receiving app determines when it checks for updates. Changes may therefore take time to appear.

How do I stop sharing my Outlook calendar?
For a published link, return to the shared-calendar publishing settings and unpublish it. For direct sharing, remove or change the person’s permission in the calendar’s sharing settings.
