When configuring your Office 365 account in an email application such as Outlook, Apple Mail or Thunderbird, you should always choose Exchange if this option is available. If your email application doesn't support Exchange, you should be able to configure your account using the IMAP settings below:

  • Incoming (IMAP) mail server: outlook.office365.com 
  • Incoming (IMAP) server port: 993 
  • Encryption method: SSL
  • Outgoing (SMTP) mail server: smtp.office365.com 
  • Outgoing (SMTP) server port: 587 
  • Encryption method: TLS
