Import AD users on Exchange server

As of I remember, last time when we were on the blog of Exchange. We were up to the configuration of Virtual Directories for Exchange server. And we have already done work with import of bulk users on our Active Directory, Importing user on Active Directory will not create an Exchange mailbox on the Exchange server. Hence, we need to effort differently to create mailbox for use users on Active Directory. If it was Exchange Server 2010, we could have done it on GUI easily. But with the Exchange 2013 and Exchange 2016, those facilities are not available. Therefore, we need to trick to import those AD users on Exchange server to create mailboxes.
