Apple Mail Setup

Apple Mail

Accounts that have multi-factor authentication enabled will need to create an app password before adding Office 365 to the Mail app.

The Mail app requires Office 365 to be setup as an IMAP or POP3 account.

IMAP is the more modern and preferred protocol.

  • IMAP
    • Server:
    • Port: 993
    • Encryption: SSL/TLS
  • POP3
    • Server:
    • Port: 995
    • Encryption: SSL/TLS
  • SMTP
    • Server:
    • Port: 587
    • Encryption: STARTTLS
