POP, IMAP and SMTP Settings for Microsoft 365
To manually set up email clients that don't support Microsoft Exchange, you'll need to find your server settings. Use your Port number (IMAP or POP) for incoming mail and your SMTP for outgoing mail. Use IMAP if you have a choice, since it offers better email synchronization across devices and accounts.
POP Settings Server name: outlook.office365.com Port: 995 Encryption method: TLS
IMAP Settings Server name: outlook.office365.com Port: 993 Encryption method: TLS
SMTP Settings Server name: smtp.office365.com Port: 587 Encryption method: STARTTLS
You may need to enable POP or IMAP for your account in the Microsoft Admin Centre. This is because IMAP / POP connections are now considered insecure. For more help, please contact us.
