I want to add birth dates for all users in the tenant and then use this information in Power Automate to create a workflow that sends Teams messages and emails on their birthdays. I don't want to store this data in a SharePoint list.

I've attempted two approaches so far:

  1. I tried to update the birth date in Delve, but I couldn't do it in bulk for all users (not optimal anyway, we are not utilizing Delve).
  2. Creating a custom security attribute in Entra ID, but I couldn't assign it to all users in bulk.

Is there another solution to add the birth date property for all users more effectively?

    There's a built-in birthday property you can leverage via the Graph API:

    birthday DateTimeOffset The birthday of the user. The Timestamp type represents date and time information using ISO 8601 format and is always in UTC time. For example, midnight UTC on Jan 1, 2014 is 2014-01-01T00:00:00ZReturned only on $select.

    You can use the standard GET/PATCH requests to work with it.
