Email not working after macOS Tahoe 26.0.1

Upgraded macOS Tahoe to 26.0.1 over a week ago. Mac is mac mini M4 (2025) with 512 GB. ALL has worked fine until yesterday (Oct 3, 2025) when 4 out of 5 iCloud email accounts refused to load. What do I do to get them back up and running? BTW 2 different iPads and 2 different iPhones and 2 different Apple watches are all fully upgraded and working fine.


Many Thanks,

Bob

Try a SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

I’m having the same issue and some others with messaging since the update. When I click on the exclamation point next to the emails it says for icloud mail: “Connections to the Server P38-imap.mail.me.com on the default ports timed out”


In every case, including my gmails, (I have many) there is a timeout error for the imap.


How do you fix this?
