iCloud email in Outlook 2016

Are you using an app specific password for your iCloud account in the Outlook password field?

See >>> https://support.apple.com/en-ca/HT204397

To generate app specific passwords, your Apple ID must have either 2 Step Verification, or 2 Factor Authentication.

Your screen shot clearly shows the email domain as @daino.com. That may be your Apple ID, but it is not where Apple sends you email. Apple has no ability to deliver your mail there via their servers.

@daino.com has their own servers and you need the IMAP and SMTP settings for it. It appears to be your corporate domain, so I suggest you consult whoever set that up for you.

My Apple ID is an @gmail address but I don't get mail directly from Apple servers at that address. I have a matching @icloud email address that would require an app specific password in Outlook.

Since June of last year, 3rd party apps. like Outlook, have required an app specific password to access iCloud mail.

I believe simply signing in to Outlook in iCloud for Windows no longer passes your Apple credentials to the Apple servers. It used to, but does not anymore.
