Before you connect
What you need
Allow IMAP access in Yahoo!メール settings
At mail.yahoo.co.jp open 設定, then メールの設定, then "IMAP/POP/SMTPアクセス". Set access from outside official Yahoo! JAPAN services (Yahoo! JAPAN公式サービス以外からのアクセス) to 許可する and switch IMAP to 利用する.
Your normal password
Yahoo! JAPAN has no app passwords: IMAP takes your regular Yahoo! JAPAN ID password. If you normally sign in without a password (SMS only), set a password first in your account settings.

- imap.mail.yahoo.co.jp:993
- SMTP
- smtp.mail.yahoo.co.jp:465
- Encryption
- SSL/TLS
Yahoo!カレンダー shut down its CalDAV interface in March 2021, so there is no calendar access for outside apps. Email works fully.
