You administer the Microsoft 365 and Power Platform environments for Contoso, Ltd. The company has a model-driven app that is used to track customer interactions with employees. The app uses standard table types for customers. A user named Elisabeth Rice signs in to the app by using the following sign in name: erice@contoso.com.
After marriage, Elisabeth changes her legal name to Elisabeth Mueller.
You need to update the sign in name for the user without losing any application history.
Solution: Ask the Microsoft 365 administrator to sign in to the admin portal and change the username.
Does the solution meet the goal?
- A. Yes Correct
- B. No
Explanation
Yes. Users of a model-driven app are Microsoft Entra ID users whose profile is synchronized to their Dataverse user (SystemUser) record. The Username managed in the Microsoft 365 admin center maps to the User Name (DomainName) field of the Dataverse user record, and this field is always synchronized. When the Microsoft 365 administrator changes the username, the same user object (same object ID) is updated and the new sign-in name flows to the existing user record in the environment. Because the user record is not replaced, all records owned by or linked to Elisabeth keep their history.
