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

At this time, Zoom does not support adding completely custom fields to the user creation form or the contact list.

However, depending on your Zoom plan and account configuration, you may be able to use existing profile fields or manage additional user information through integrations such as SCIM or your identity provider (e.g., Microsoft Entra ID or Okta) if your organization syncs users from a directory service.

If you specifically need fields like:

• Business Unit
• Department
• Sub-Department
• Location Manager

to appear in the Zoom user creation form and contact list, this functionality is not currently available as a native feature.

I recommend submitting this as a feature request through the Zoom Community or the Feedback option in the Zoom desktop app. Many organizations would benefit from the ability to define custom user attributes and display them in the contact directory.

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..?
