From FarmShare

Alpine and Mutt are installed in the Cardinal environment, but not on FarmShare 2; FarmShare 2 users can install either application using a local package manager like Linuxbrew, but these applications are not supported there. The following configurations should work with Stanford e-mail accounts hosted by Microsoft Office 365.

NOTE: Microsoft will require the use of "modern" authentication starting October 1, 2022. Alpine and Mutt support this authentication method, but not in the versions currently installed on cardinal systems. Users will need to install more recent versions using a local package manager until the cardinals can be upgraded.

Enable IMAP

IMAP and POP services are disabled for many users as a security precaution, including all users with accounts created after October 31, 2017, and existing users that have not used an IMAP (or POP) e-mail client in the recent past. If you would like to use Alpine or Mutt to check mail on FarmShare machines you can request that IMAP be enabled for your account by submitting a HelpSU request.

Alpine Configuration

# ~/.pinerc
smtp-server=smtp.office365.com/submit/tls/user=${USER}@stanford.edu/auth=xoauth2
inbox-path={outlook.office365.com/tls/user=${USER}@stanford.edu/auth=xoauth2}Inbox
folder-collections="IMAP Folders" {outlook.office365.com/tls/user=${USER}@stanford.edu/auth=xoauth2}[], "Local Mail" ~/Mail/[]
default-fcc={outlook.office365.com/tls/user=${USER}@stanford.edu/auth=xoauth2}Sent Items
postponed-folder={outlook.office365.com:/tls/user=${USER}@stanford.edu/auth=xoauth2}Drafts
default-saved-msg-folder={outlook.office365.com/tls/user=${USER}@stanford.edu/auth=xoauth2}Archive
trash-folder={outlook.office365.com/tls/user=${USER}@stanford.ed/auth=xoauth2u}Deleted Items
ldap-servers=ldap.stanford.edu "/base=cn=people,dc=stanford,dc=edu/impl/tlsm/nick=Stanford Directory"

Note: The ${USER} expression automatically substitutes your local username. If you are configuring Alpine on a system where your local username differs from your SUNet ID you must replace the entire expression with your SUNet ID.

Mutt Configuration

A mutt configuration that should work with Office 365 requires an external script to manage authentication, which is documented here.
