SMTP Setting Locations in Common Mail Apps


In the fall of 2019, smtp.cornell.edu will no longer work as an outgoing server setting for outgoing email.

The recommended ways of using Cornell email are:

  • For Cornell Office 365 mail, any Outlook-branded app or Apple Mail for macOS.
  • For Cornell G Suite, using the web interface at gsuite.cornell.edu.

If you choose to use an app other than Outlook or Apple Mail for macOS with Cornell Office 365, using one that connects using the Exchange protocol (Apple and Google products have this option) will be less likely to produce unexpected behavior.

For more complete information about the settings below for Office 365, see Other Ways to Manage Your Cornell Email. For more complete information about the settings for G Suite, see Google's Use IMAP to check Gmail on other email clients.
