If youâre using Office 365 for business or other Microsoft Exchange-based email, you can find your Post Office Protocol 3 (POP3) and Internet Message Access Protocol 4 (IMAP4) server settings by using Outlook Web App.
SMTP is the protocol used to <send> new mail regardless of what protocol is used to <retrieve> new email which is why POP3 and Imap accounts are shown as POP3/SMTP and Imap/SMTP account types in the Outlook account settings. All external internet email is sent using the SMTP protocol from an SMTP server.
