What Is SMTP?
• Any email client's most fundamental feature is sending emails, and Outlook is no different. The SMTP settings need to be set up correctly in order for your email to be sent without any issues.
• The common system for transmitting emails over the internet is called SMTP, or the Simple Mail Transfer Protocol. Your email client's SMTP server is in charge of sending outgoing emails to the recipient's mail server. By establishing a connection with the SMTP server and sending the email to the recipient's mail server, your email client transmits the message, which is subsequently delivered to the recipient's inbox when you click the "Send" button.
