How to Share a Calendar Link in Outlook for Others

To share an Outlook calendar as a link, open Outlook on the web, go to Settings > Calendar > Shared calendars, choose the calendar and viewing permission under Publish a calendar, then select Publish and copy the HTML or ICS link. The HTML link opens a browser view; the ICS link lets someone subscribe in a calendar app. Publishing is different from inviting named people to a private calendar, so choose the option that fits your audience and privacy needs.

What You’ll Need

An Outlook account and access to the calendar you want to share. Publishing is available for many Outlook.com and Microsoft 365 work or school accounts, but an organization administrator can turn it off.
A browser and an internet connection. Outlook on the web is the most consistent place to find the publishing controls; use the account that owns or manages the calendar.
A decision about what recipients should be able to see. Depending on the account, the permission choices include availability only, titles and locations, or full details.

Step-by-Step

Decide whether a published link is appropriate. A published calendar link is designed to let people view a calendar without sending a separate sharing invitation to each person. Anyone who gets a working link may be able to use it, so do not publish a calendar containing private appointments or sensitive details unless the permission level is suitable. If access must be limited to specific people, use Outlook’s calendar-sharing invitation instead; that is not the same as a public link.
Open Outlook on the web and select the right account. Sign in at Outlook on the web with the account that owns the calendar. Select the Calendar icon, then check the calendar list to identify the calendar you intend to share. If you have several calendars, such as a personal calendar and a team calendar, confirm the name before continuing. Publishing the wrong one can expose unrelated events.
Open the publishing settings. Select the Settings gear, then go to Calendar > Shared calendars. Find the section named Publish a calendar. If the settings pane is narrow, scroll within it or expand the relevant section. In new Outlook for Windows, the settings route is generally the same. The classic Outlook for Windows desktop app may show calendar-sharing controls, but it does not provide the same publishing options in every account configuration; use Outlook on the web if you cannot find Publish a calendar. On Mac, use Outlook on the web for this publishing workflow rather than relying on a desktop menu that may vary by version.
Choose the calendar and permission level. In Publish a calendar, select the calendar from the dropdown. Choose the least revealing permission that meets your need. Availability-only access shows when you are busy without displaying event names. A titles-and-locations option reveals more, while full details can show appointment information such as descriptions or other event data. Exact labels can vary by account. Do not assume that publishing changes only the events you create; check the selected calendar and permission carefully before making the link.
Publish the calendar. Select Publish and wait for Outlook to create the links. If you change the calendar or permission selection, publish again if the page prompts you to. Outlook provides an HTML link and an ICS link. Treat both links as access credentials: avoid posting them publicly or sending them to people who should not see the calendar.
Copy the link that suits the recipient. Choose Copy next to HTML when you want a link that opens a readable calendar page in a web browser. Choose Copy next to ICS when the recipient wants to add the calendar to another calendar app as a subscription. ICS is not simply a normal web page link. Depending on the recipient’s app, it may be called an internet calendar or subscribed calendar, and updates may appear after that app refreshes its subscription.
Send the link with a short explanation. Paste it into an email, message, or other appropriate channel. Tell the recipient whether it is the browser-view link or the subscription link, what calendar it opens, and what level of detail you have allowed. For example: “This HTML link shows my availability calendar. The ICS link is for adding it to a calendar app.” Avoid sending both links without explaining the difference.
Check that the link works and review access later. Open the HTML link in a separate browser window or ask an intended recipient to check it. A private window can help reveal whether the page requires a sign-in, but behavior can vary with the account and organization’s policies. If the link does not show the expected calendar, revisit the publishing settings and confirm the selected calendar and permission. When you no longer want to share it, return to the same section and select Unpublish, if available. Recheck after changing permissions or removing publication; recipients may already have copied or downloaded calendar information.

Common Mistakes

Using Share Calendar when you need a link. Share Calendar usually sends a permission invitation to a person or group. That is useful for controlled, named-person access, but it does not necessarily create a link that anyone can open. Use Publish a calendar for an HTML or ICS link when your account permits it.
Choosing full details by accident. Full-detail publication can reveal more than busy times, including event names and other information. Select the minimum permission needed, and review the calendar for sensitive events before sharing.
Sending the wrong link type. An ICS link is intended for subscription in a calendar program; recipients may not see a normal browser page when they open it. For a simple view in a browser, send the HTML link.
Assuming the link is restricted to its recipient. A published link can be forwarded. Do not treat possession of the link as proof of identity or as a substitute for a private, individually granted permission.
Expecting instant updates from an ICS subscription. Calendar apps refresh subscribed calendars on their own schedules. A change you make in Outlook may not appear immediately in the recipient’s app.

Tips

Use a separate calendar for events you are comfortable sharing. That makes it easier to publish a useful schedule without exposing personal appointments stored in your main calendar.
Choose availability-only access when people just need to find an open time. If they need to know what an event is called or where it takes place, grant a more detailed level only after considering the privacy implications.
Tell recipients whether they should bookmark the HTML page or subscribe using the ICS link. If they import rather than subscribe, their copy may not keep updating; the exact wording and behavior depend on their calendar app.
Review the published calendar occasionally, especially if your needs change or the link has been shared widely. Unpublishing stops future access through the published link, but it cannot erase information someone has already copied, saved, or captured.
For a small group that needs to edit events or have individually controlled access, use a sharing invitation with the appropriate permission instead of a published view-only link. Check the available options for your account before promising editing access.

Troubleshooting

I cannot find Publish a calendar. Confirm that you are signed in to the account that owns the calendar and are using Outlook on the web. Some work or school administrators disable external calendar publishing, and some account types or calendar configurations may not offer it. If the option is absent, ask your Microsoft 365 administrator whether publishing is allowed. If it is not, share with named people using the available calendar-sharing feature or ask about an approved alternative.

The link opens an error page or asks the recipient to sign in. Confirm that you copied the complete link from the correct row and did not accidentally copy the ICS address when you meant to send the HTML address. Test the link in a separate browser session. An organization’s policy, account restrictions, or recent changes to publication can affect access. If external viewing is blocked, a recipient sign-in may be required or the link may not be usable outside the organization.

The recipient sees too much or too little. Return to Settings > Calendar > Shared calendars and check the selected calendar and permission level under Publish a calendar. Change the permission to the appropriate level and republish if Outlook asks you to. Then send the current link again. If privacy is a concern, unpublish the calendar while you review the settings; do not rely on a message asking recipients to ignore details they have already seen.

New events are missing from an ICS subscription. First check whether the event is on the calendar you published. Then allow the recipient’s calendar app time to refresh, or ask them to use its refresh or update-subscription control. Removing and adding the subscription again may help if it has become stuck, but the steps differ by app. Avoid importing the ICS file as a one-time copy if ongoing updates are required.

Frequently Asked Questions

Can I share an Outlook calendar link with someone who does not use Outlook?
Often, yes. The HTML link can be opened in a browser, and many calendar apps can subscribe to an ICS link. Their organization’s settings or app may still block access, so test the link with the intended recipient.

What is the difference between an HTML link and an ICS link?
HTML is intended to display the published calendar in a browser. ICS is a calendar subscription address that another calendar app can use to retrieve events and updates. The receiving app determines how it presents and refreshes the subscription.

Can I share only my free and busy times?
If your publishing settings offer an availability-only permission, select it before publishing. The exact label varies. Review the setting rather than assuming a link automatically hides event titles.

Can I make the link accessible only to one person?
A published link is not the best way to enforce person-by-person access because it can be forwarded. Use Outlook’s sharing invitation for named people when your account supports it, and grant only the access they need.

How do I stop sharing the link?
Go back to Settings > Calendar > Shared calendars, find the published calendar, and select Unpublish if that control is available. If you cannot unpublish it, contact your administrator or check the account’s sharing settings. Remember that stopping the link cannot remove copies already saved by recipients.
