Possible fixes

The app password is the one used to connect to the IMAP and SMTP servers, but it doesn't work since it's the real password that has to be used, causing the connection error.

Workaround

• Click on the notification (the error message)
• Change the password from the app password to the real password
• It now downloads the emails
