New Outlook stopped syncing my iCloud email

Switched to the new Outlook on Windows a week ago. iCloud mail came across at first but nothing new has arrived for days. The Gmail account in the same app syncs fine. Do I need an app-specific password again?

you need two-factor turned on for your Apple account before it'll let you create an app-specific password at all. and if new Outlook won't auto-detect it, add it as IMAP manually: imap.mail.me.com port 993 with SSL, and smtp.mail.me.com on 587. your username is the full iCloud email address.

Did you change your Apple ID password recently? That kills every app-specific password, and Outlook needs one for iCloud - your normal Apple password won't work there. Go to your Apple account page, Sign-In and Security > App-Specific Passwords, make a new one, then in Outlook remove the iCloud account and add it back using that new password. Just updating the password in the existing account was flaky for me, removing and re-adding sorted it.
