How to remove users' extensions using the Remove-MgUserExtension cmdlet

What is the Remove-MgUserExtensioncmdlet?

The Remove-MgUserExtension cmdlet is used in Microsoft Graph PowerShell to delete extension attributes from a user object in Microsoft Entra ID.

Extensions are custom attributes added to Microsoft Entra ID user objects for storing additional information. Over time, some of these attributes may become obsolete, redundant, or no longer relevant to business processes. The Remove-MgUserExtension cmdlet is particularly useful for maintaining data hygiene by ensuring that only necessary and up-to-date attributes are retained, reducing clutter and minimizing security risks associated with storing unnecessary user data.
