Link Public Holiday list to all my office users

Hello @Jesse Sharmila Raj,

Based on the information you provided, I understand that you would like to add holiday calendar events for all users across your organization.

You can leverage the "Direct to Calendar" functionality available in Exchange Online. This feature allows meeting requests to be automatically added to users' calendars, eliminating the need for them to manually accept the invitation. As a result, the holiday event can be populated directly to users' calendars, helping ensure consistency and reducing administrative effort.

For more information about this method, please refer to the Microsoft documentation: Use mail flow rules to automatically add meetings to calendars in Exchange Online | Microsoft Learn

I hope this information is helpful. Please let me know if you have any further questions.
