Apple Mail imap not working even though Email Configuration is correct

Greetings phoonies,

Thank you for using Apple Support Communities. It seems like you are not able to receive emails on the Mac, but you are on your iPhone. We would recommend you use this article for more information. We'd like to specifically call out this section/information.

• "Try quitting Mail, then opening it again.
• Choose Window > Connection Doctor, then follow any instructions in the Details column. Check for problems logging in to email accounts or with the incoming mail server, or with firewall software blocking network traffic.
• Check whether you’re affected by another firewall, such as software installed separately from macOS or built into an internet sharing router, or administered by your email account provider. Contact the appropriate person for information.
• If you’re still having problems, contact your email account provider to verify your user name, password, incoming mail server, and other required information. Then verify the information is entered correctly in Mail account preferences."

Greetings phoonies,

Thanks for the update. Since one of the three accounts will connect, another thing you could do is to remove the 2 accounts that are not syncing and add them back again.
