Yahoo mail stopped downloading into Outlook (Microsoft 365)

My Yahoo account was pulling into Outlook on my desktop for years, then a few weeks ago it just stopped. Send/receive shows a server error. I re-entered my password twice. Do Yahoo accounts need an app password now?

Before you redo the account, log into Yahoo in a browser and check the mail is actually arriving there. If the mailbox is full or a filter is moving it out of the inbox, Outlook has nothing to pull. And if it's classic Outlook, look at Send/Receive Groups and make sure the Yahoo account is still included. After an update I've seen it just drop out of the list.

Nine times out of ten that's Yahoo refusing your normal password. Outlook needs an app password for Yahoo now. In Yahoo: Account info > Account security > Generate app password, give it a name, copy the code. Then in Outlook remove the Yahoo account and add it again, and when it asks for the password paste the app password, not your usual one. If it won't set up automatically, choose IMAP manually: imap.mail.yahoo.com, port 993, SSL, outgoing smtp.mail.yahoo.com 465.
