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,

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.

Have you tried removing the account(s) and reentering them in Mail?
Delete the account from Mail and put it back in.
Sounds like I was having the same problem.
When I would hit send, it would get hung up and not send. After multiple calls to apple support a tech told me to go to settings/composing/check spelling: (I had, 'when I send' selected, but I was instructed to change it to 'never'). So far so good problem solved, but...
I asked how she knew about that fix and she said she recieved a 'work around' notice for this issue.
I'm a big Apple fan and am afraid they are really starting to faulter badly. Don't ge me started on the ****** AI debacle....
I have tried everything to sort this issue - reloading settings a few times too. BUT the only thing that works is turning spell checking to NEVER.
Or, put a deliberate spelling mistake in your email (I add an z to a simple word) and then after you correct it before sending (with spell check on sending ON) it sends!
Apple - please send out an update to sort this!
There is the alternative until a fix is found that you access the accounts via your browser.
There was another suggestion on another thread earlier today that if you allowed Mail Full Disk Access it might work.
Not yet. I still have the 4 out of 5 accounts that refuse to load. But, and that's a big but, while working on the only one that loads right away one of the others loads and is again usable! Later, it went back to its unloaded state. Then, 10 minutes later it's back up again. All I have to say now is that macOS Tahoe 26.0.0 worked as advertised, and 26.0.1 the bug fix, turned out to be a bug creator!
BTW, I have submitted a "Feedback Assistant" description of the problem to Apple. I hope the Gurus in Apple get it really fixed ASAP. 'Steve' we miss you.
This is happening to me too since the update of 26.0.1. Mail app is not responding and in spinning ball of death. I have removed all of my email accounts including iCloud. Still not working. This is not like Apple to let a bug go so long without being fixed. I am having flashbacks of using Windows OS.
I've got the same problem. Accounts work fine on iPad and two iPhone. Nothing but frustration and failure and countless hours of deleting, reinstalling, starting in Safe Mode, force quitting and hunting message boards - nothing.
I tried this and no luck. I also tried turning off Siri and Apple Intelligence just in case they were trying to also index emails. No luck still. Mail App is still in “Not Responding” mode = Spinning Ball of Death.
I have hesitated to respond to the suggestions that have been submitted, especially by AlWeir. Thank you for trying, Al. The reason for my hesitance has been the problem went away on its own. First 1 of the 5 cleared up. Then a day later another one cleared up. At this point I was elated. Then, on the next day, 2 more came back. Now I figured that since the remaining one was not used at all, just a vestige of the past, I deleted it from macOS mail and all 4 are continuing to work properly.
In my search for a solution the only thing I could find as a possible cause was that the accounts were not using the correct outgoing servers. I typed in the correct ones but it didn't seem to make any difference. But then, the next day they were OK. I can't figure out the real cause of the problem, so I hope the next "Bug Update" that seems to be coming out soon will kill more bugs than it creates.

The 2iPads, 2 iPhones, and 2 AppleWatches were never affected with this problem; and yes I could log into iCloud accounts on them. The only device that had the problem was the M4 Mac mini; and it went away on its own as outlined above.
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?
I have exact issue. Multiple yahoo account and even iCloud and gmail don’t work on Tahoe 26.0.1 Mac, but all work great on iPad and iPhone. Have deleted internet accounts and te added several times.
