Add contacts to all mailbox folder in Exchange Online

Regular Contributor

I want to add a contact to all contact mailbox folders on our Exchange. How should I proceed?


Use case is: we have a few emergency contacts in our organization and we want that every employee has that contact. So, I need to add the emergency contacts somehow to all contact folders in Outlook of all our employees.
