Outlook lets you share your calendar with individual people, but you can also publish your calendar so that anyone with the right link can see it. Here’s how to do that and why you might find it useful.
What’s the Difference between Sharing and Publishing?
You can make your Outlook calendar available to other people in two ways:
Share your calendar. When you share your calendar, only the person you share it with can see it. You can share your calendar multiple times and manage each share individually. For example, you can share your calendar with Alice and then share it with Bob; later on, you can remove Bob’s access while keeping Alice’s access. Sharing is the best option if you want to be certain that only people you choose can see the calendar.

Publish your calendar. When you publish your calendar, anyone with the link can see it. Anyone finding the link by accident is all but impossible, although people could share the link with others. Publishing is all or nothing, so if you remove the publishing link, it won’t work for anyone. Publishing is the best option for a public calendar that multiple people need access to, such as your project team at work, or a sports team you organize on the weekend.
A quick note for people using corporate IT: A lot of companies make their staff calendars internally visible by default. This allows everyone in your organization to see each other’s calendars, which makes booking meetings much easier. This is not the same as publishing your calendar, which is primarily used for sharing your calendar with people outside your organization.
How to Publish Your Outlook Calendar
In previous iterations of Outlook, you could publish your calendar from the Outlook client on your laptop. But since the introduction of Office 365 (O365), Microsoft allows you to publish a calendar with people outside of your organization only by using the Outlook web app.
Log in to your O365 account and navigate to Outlook by clicking on the app launcher (the 9 dots in the top-left corner) and selecting the Outlook icon.
