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?
When 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 Outlook.com 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.
Adding a Holiday Calendar via Outlook on the Web
After logging in, select your Calendar.
Click the “Add Calendar” link in the Calendar Navigation Pane and in the dialog that opens select “Holidays”.
You can now click on 1 or more countries to directly add that Holiday Calendar to your mailbox.
Calendars in Outlook
After you’ve added the Holiday Calendar in Outlook on the Web, it will automatically get added to Outlook on the desktop as well after a few minutes or once you restart Outlook.
Holiday Calendars in Outlook.
You can select multiple Calendars like your regular Calendar, the Birthday Calendar and the Holidays Calendar and they will conveniently show as a single Calendar thanks to Overlay Mode.
The Birthdays and Holidays will show up color-coded based on the chosen color for that specific Calendar folder.
