Add Custom Attributes to Contact List and User Accounts in office 365 Admin

I would like add custom attributes to the contact list as well as to user accounts during the creation process. The required attributes are as follows:

Business Unit

Department

Sub-Department

 Location Manager

Kindly anyone advise on the procedure to configure these attributes and enable them in the contact list and user creation form.

    Microsoft 365 does not natively support adding custom fields such as Business Unit, Sub-Department, or Location Manager directly to the user creation form in the Microsoft 365 Admin Center.

    The department is already available as a standard user attribute, while Office Location can be used for location-related information.

    For additional attributes, consider:

    • Microsoft Entra ID extension attributes
    • Custom security attributes
    • Microsoft Graph or PowerShell-based provisioning
    • Integration with an HR or identity management system

    If your requirement is to display these custom fields directly on the Microsoft 365 Admin Center user creation page, this is not currently supported out of the box and would require a custom provisioning or identity management solution.

    HR applications like Workday and BambooHR has fields which can use extensionAttributes for your purpose. 

    Microsoft provides 15 pre-defined extension attributes (extensionAttribute1 to extensionAttribute15) that can be reused.

    You can map your requirements as:

    • Business Unit → extensionAttribute1
    • Sub-Department → extensionAttribute2
    • Location Manager → extensionAttribute3

    Isn't it quicker to just ask me? 20 people will run data on contacts for 2 full years and in the end you will realize that the "contacts" are..?
