Add Holidays to your Microsoft 365 Exchange Online or mailbox

I’ve been looking for an option to add a Holiday Calendar to my Exchange mailbox in a similar way to the Birthday Calendar, which displays as a separate folder in Outlook. I haven't found out how to do it though.

Is there a way to add a separate Holiday Calendar to my Outlook Calendar as well?

Holiday Calendar buttonWhen you have your account configured in Outlook, you can import Holidays into your main Calendar folder. The downside of this method is that it isn’t updated automatically and only shows a limited time into the future.

To add a separate, always up-to-date, Holiday Calendar to your Exchange Online or mailbox, you’ll have to use Outlook on the Web (OWA).

Once you’ve added the Holiday Calendar via Outlook on the Web, it will automatically sync with Outlook as well.
