In organisations that have moved to Office 365, or are moving to Office 365 while using a hybrid setup with an on-premises Exchange 2010, 2013 or 2016 server and/or Lync/Skype, your helpdesk tools and scripts need to be adjusted.
While previously, you would provision your account in Active Directory, the mailbox on the onpremises Exchange Server and voip functionality on the Lync/Skype server, after your migration, you no longer need to provision mailboxes or lync accounts on premises. After a user has been migrated to Office 365, his ‘user type’ in the Exchange on premises server is ‘Remote Mailbox’. But for new users, this is not set automatically.
If you’re using scripting or tools like ADManager, you can use some simple Powershell commands to set the correct properties on a newly created user.
Configure and run below script on your Exchange server (or use a remote session in the script) to fully provision your existing non-mail enabled user on premises as a Remote Mailbox.
This script will comply with your Recipient settings in Exchange (email proxies). It should be easy to adjust the script to also include licensing, or anything else that is currently done manually. Let me know if you need any help 🙂

Hello
I gone thru your script and like the approach. Before test this script, I want t understand that creating user and its email box, how much time it will take for sync with Azure.
