Managing holidays and birthdays calendars for all users.

[Bogdan Kulish]

Hello to all. Is it possible to manage the holidays and birthdays calendars for all users in M365 admin console, like bulk remove birthdays calendars for users or add / change country for holidays calendar?

You will need some EWS/Graph API based script for that, here's a sample one: https://developermessaging.azurewebsites.net/2014/06/03/ews-importing-bank-holidays-from-an-outlook-...

Hello @Bogdan Kulish,

looks like i'm faced with the same challenge you had some time ago. Trying to find a solution to disable/enable the birthday calendar for multiple users on backend side (by using Powershell/EWS/GraphAPI).

Did you manage to find a working approach and are able to share it?

Anyone else is also welcome to join in ;)

Thanks and cheers!
