hi

- Hi Tien Ngo Thanh,
SMTP is usually used with POP3 configuration - so the easiest answer to this is to disable POP3 and IMAP4 protocols on the users mailboxes in the Exchange Online Admin Centre or via Powershell

Best, ChrisChrisHoardMVP SO if I need allow one user can use smtp then only need allow POP3 and IMAP ?
- Correct - it can be managed on a mailbox by mailbox basis so you can turn on or leave one on. To be exact it is only disabling POP3 protocol as SMTP is used alongsisde POP3 for the outbound, however we tend to manage IMAP alongside POP3 as both are considered legacy protocols.
Hope that clarifies!
Best, Chris
