If you use line-of-business applications that send e-mail or you receive system health reports in e-mail, you can continue to receive them after Exchange Server is removed. If these conditions do not apply to your environment, you do not need to complete the procedures in this section.
To continue to receive e-mail from your server, you must install the Simple Mail Transfer Protocol (SMTP) service to enable your server to relay e-mail to Exchange Online. You must also set the service to start automatically, and you must configure the service to communicate with Exchange Online.
