Change Users UPN automatically with scheduled task

How to combine PowerShell with a scheduled task to change Users UPN automatically? Why do we want to change Users UPN automatically? First, I always say that if you can automate the process, you should do it. Second, all the accounts that are being created in Active Directory need the correct UPN suffix.

By automating the task, you make sure that it will automatically change the Users UPN and sync with Azure AD Connect to Azure. In this article, you will learn how to change Users UPN automatically with a scheduled task.
