3. Run pine.
4. Select SETUP -> Config.
5. Change the inbox-path to {<outlook.office365.com>}INBOX,
   e.g., {outlook.office365.com}INBOX.
6. Exit SETUP.
7. Press Yes to save the setting.
8. Next time when you run pine, you will be prompted to input your e-mail username and password.

1. After login your Unix Account, you can edit your .pinerc file manually.
