Mail not working after update iOS 18.1.1

After updating iOS to 18.1.1, the mail app is not working. It is totally malfunction and can’t receive nor send email. Start the mail app, it just pops up a white screen. I have tried to offload the app and reinstall it. It’s the same. When I hard reset the phone, it can pop up the mail account list but freezes. How do I fix it?

iPhone 14 Pro Max, iOS 18

Solution: Go to Settings. Click your name at the top to access your Apple Account. Look for a notice at the top of your Apple Account page that asks you to accept the new terms and conditions for Mail. Accept the new terms.


Context: Apple has introduced new AI features with Mail that requires the terms be accepted and it is causing all sorts of issues with the Mail app until you accept the new terms. I was having issues with Search, Sending mail, and indexing had also halted. Once I accepted these terms, everything worked perfectly again.


One more thing: Go to Settings > iCloud. Check the iCloud backup status. Mine had been halted, so it wasn't backing up. You may need to click Back Up Now after you've accepted the terms.


My usage situation: iPhone, Mac Mail user, iCloud account, Mac email account only. The only issue I had was on the iPhone Mail app (Mail was working fine on my Mac desktop and laptops). If this isn't your situation, then your mail issue may be different to mine.


Hope this helps someone!

Or Apple could fix their mistake. It worked before the update. It didn’t work after the update. Screwing up thousands of people’s emails and blaming them or their email provider is adding insult to injury. The phones are expensive. I shouldn’t have to work my way through a laundry list of things that don’t work, and I shouldn’t need to reconfigure my phone or email providers. Apple screwed it up. They should fix it.

If you are that convinced the problem lies with Apple, tell Apple:

There is no mistake. Apple ADDED FEATURES to email, but provided a way to turn them off for users who don’t want them. What mistake are you talking about? Or didn’t you read any of this thread or the release notes: What’s new in iOS 18 - Apple Support

I have no issues. I’m just a user like you in this user-to-user forum.


if you describe YOUR issue, or just read the thread you have posted to, whatever your issue is can be resolved. But you have to tell the other users here what it is. Unless your only purpose is to rant and not actually fix whatever the problem is.

I have now updated my iphone and ipad to ios 18.3.1 but still my email doesn't work. I've removed all my email accounts except iCloud. I've sent a test email from my Mac to my iCloud account (just says "hello, how are you" -- no attachments) and it takes about 15-20 minutes before it appears on my iphone and ipad -- the little wheel just goes round and round till the email finally appears --I'm just so fed up with this. My iphone is a new one and it's now rubbish. Even iCloud mail is so slow, never mind my third party accounts (Yahoo, Microsoft).


Things I've tried: 1) removing accounts and adding them again, (2) restarting the iphone & ipad, (3) turning VPN off, (4) changing iphone mail to List View as someone here suggested. None of these makes any difference.


Question: someone suggested that Categorising is going on in the background even when you've selected List View -- does this slow things down? Even so, the Categories/List View is only available on my iphone, not the ipad. The ipad doesn't have the Categories/List View option at all, and it's still really slow.

Tried it unfortunately that didn’t help me either. I still am constantly getting a message. That’s indicating that it’s not communicating with the exchange or something. I did not get all of these messages every single day before the update. I reboot in my phone several times. It’s gotta be the iPhone because my Microsoft computer works just fine, but having to go to my laptop computer to read emails is getting a bit frustrating. Apple just doesn’t seem to take any of these things seriously because there are so many people complaining about the same thing and yet what is Apple doing?
