Office 365

The campus e-mail infrastructure is moving to Office 365, a cloud solution from Microsoft, in Summer 2015. Current users of the Alpine (Pine) and Mutt e-mail clients may need to modify their configurations at that time.

Alpine Configuration

# ~/.pinerc
smtp-server=smtp.stanford.edu:465/ssl/user=${USER}
inbox-path={outlook.office365.com:993/ssl/user=${USER}@stanford.edu}Inbox
default-fcc={outlook.office365.com:993/ssl/user=${USER}@stanford.edu}Sent Items
postponed-folder={outlook.office365.com:993/ssl/user=${USER}@stanford.edu}Drafts
default-saved-msg-folder={outlook.office365.com:993/ssl/user=${USER}@stanford.edu}Archive
trash-folder={outlook.office365.com:993/ssl/user=${USER}@stanford.edu}Deleted Items

Mutt Configuration

# ~/.muttrc
set smtp_url="smtps://$USER@smtp.stanford.edu/"
set folder="imaps://$USER%40stanford.edu@outlook.office365.com/"
set spoolfile="+Inbox"
set postponed="+Drafts"
