How to Get Your Outlook / Microsoft 365 Calendar ICS Link

To convert your calendar, CalConverter needs your Outlook ICS publish link (a URL ending in .ics). The tricky part: this link is well hidden, and most people look in the wrong place.

Important: where it is not

• Not in the Outlook desktop app. The installed Outlook (Windows or Mac) does not expose the ICS publish link at all.
• Not by right-clicking the calendar. The option isn't in the calendar's context menu.

You have to use Outlook on the web, and it lives under Settings — not on the calendar itself.

Step by step (Outlook on the web)

1. Open outlook.office.com (work/school) or outlook.com (personal) and sign in.
2. Click the Settings gear in the top-right corner.
3. Go to Calendar → Shared calendars.
4. Under Publish a calendar, choose the calendar you want and set the permission to "Can view all details".
5. Click Publish. Two links appear — an HTML link and an ICS link.
6. Copy the ICS link (the one ending in .ics). That's what you paste into CalConverter.

If you don't see "Publish a calendar"

On work or school accounts, calendar publishing can be switched off by your Microsoft 365 administrator. If the option is missing or greyed out, ask your IT admin to enable calendar publishing for your account.

One privacy note

The ICS publish link is public to anyone who has it — that's how Google and Apple read it. Don't share it openly, and avoid publishing calendars with sensitive or confidential entries.
