Mail not working after update iOS 18.1.1

I got you beat 2 hrs on Saturday with a regular tech then 1/2 hr with a senior tech. Then 10:30am-9pm today. Sending reports to engineers Centurylink sent me a message stating it’s coming from the 18.1 update from Apple and it’s widespread. CenturyLink on top of it LOL

One would think that a company worth 3.5 trillion dollars, u.s., would work the bugs out of software before putting it out for their customers to use. But no, it appears we are the canaries that tell them when things go dark in the coal mine, and/or worse. Thanks.

Recent update to ios 18.1.1 no longer allows for photos to be added to emails. Why?

This is beyond frustrating - my emails will not load - I get the spinning wheel of death - it’s not our network or anything else as everything works fine on my work Android using the same email addresses - this began as soon as I did the update and I’m so frustrated. Please fix this asap, Apple!!

This is now my third or fourth post since September 2024.

The problem began with the original iOs18 Update.

I am now running 18.2.1 on an iPhone 12 mini and have restarted, reset, adjusted email settings [i.e / slash etc]. I have communicated with my hosting company, for over 30 years, [ prohosting.com ]on numerous occasions and they have advised since Sept/Oct 2024 that they are "aware" of the issue but cannot offer any other solution other than changing email clients.

This is the latest response from support at ProHosting.com

" We are aware of the issues with devices running iOS 18, this also includes the newly released iPhone 16. The stock mail app on these devices cannot connect to the ProHosting mail servers. The short term fix would be to install a different app for checking your mail on the affected devices."

I have multiple accounts on different servers and *ALL* stopped receiving/sending on the day I updated the iOS.

It is not clear to me whether this is an " either / or " problem. Whether it is exclusively an Apple bug, a hosting provider bug [i.e certificates etc ] or whether it is a combination of both.

What is clear is that *NEITHER* Apple nor hosting/mail providers are forthcoming with any *DETAIL* regarding the blockage/failure/bug that *CLEARLY* is affecting a substantial minority of users, apparently because neither appears to consider it "their" problem.

What is TRUE, is that basic functionality of the Apple Mail App STOPPED after the iOS 18 Update [ or iterations] and it has NOT recovered since.

NO RESPONSE *IS* a Response. It would at least assist the LARGE minority of users experiencing this bug to proceed with some logical trouble-shooting if Apple would *acknowledge* the users requests and provide canonical guidance.

Apple??

I have the same problem on my iCloud email and yahoo emails, apple needs to send a fix, nothing I have tried works. Every time there is a new update something goes wrong.

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.

Whenever I try to manage messages, the sheet menu will not stay visible.

if I open a mailbox and select a couple of messages, then I tap "Move" to move those emails to a subfolder, or even trying to delete multiple emails...

the sheet menu opens and closes immediately. Before I can select an action.

This 18.1.1 update has caused major problems with organizing emails in just a few days.

So l have a sneaking suspicion that there is more to this than we all know. The update was suppose to improve mail. Instead with AI involved l think it’s meant to read through the mail faster 🧐. Also explain this, my husband’s iPhone is older so he doesn’t get updates. But his third party mail is still affected hmm. Like l said more to this than we know. iPhone sales slowing down in China. I read Apple was hoping everyone will update their devices. I don’t have the funds to update. The current problem is draining my battery faster. Apple gonna replace my battery?

I had 8 email accounts on my iphone.

After the iOS 18.1.1 update, I had to delete each one, close my email app and close Settings, turn off my phone, turn my phone back on, go back into Settings/Apps/Mail/Accounts and add my email accounts ONE BY ONE... turning my phone off/back on in between each Add.

Frankly, I cringe every time I get a notification for an iOS Update. If I ignore it for too long; my phone becomes glitchy. But if I diligently load the Update when notified; then there is ALWAYS some sort of collateral damage. You would THINK that with a development division as large & experienced as Apple's, they would find these issues during Beta-testing and correct them BEFORE sending out the Update.

Following on from earlier post, the mail icon has been moved to the apps section instead of the first page in settings.

My new iPhone 16 pro max same thing with emails from my server..

with Apple support for about 2 hours they are going ask the engineers tomorrow..

Apple this update IOS 18.1.1 is destroying my sanity! Emails are not coming in on my husbands iPad! One account comes in, his personal one doesn’t work at all. I deleted the account changed the password, reinstalled it and it still doesn’t load the emails! You need to fix this problem! You can see from this thread that it has been happening to multiple people! Please fix it! (It works on phone but not on IPad)

I posted this earlier with the link but Apple removed it.

I think the only solution is to contact your third party email provider with this information below and demand they fix the issue at their end. I’m not sure why some users are having a problem with iCloud.com accounts since that’s an Apple product.

A lot of users have pointed out that the problem seems to stem from how Apple Mail handles connections with IMAP servers after the iOS 18 update. 

The heart of the issue? It looks like iOS 18 has become a bit pickier with security certificates — especially if you’re using a self-signed certificate.

Essentially, the system may no longer trust these certificates, even though they worked just fine in iOS 17.

The strange part is that it’s not only the self-signed certificates causing trouble. Even users with legitimate SSL certificates (the kind you expect to work without issues) are facing the same syncing errors. 

The Mail app seems to have difficulty “talking” to the IMAP servers, and in some cases, it’s flat-out refusing to fetch new messages.

Possible Culprits

While Apple hasn’t officially commented on the situation, there are a few things that could be contributing to this glitch:

Stricter Security Requirements: iOS 18 may have tightened its policies on how it handles email server connections, particularly with certificates. 

This could explain why previously accepted certificates are now getting rejected.

TLS Version Issues: Some users have speculated that the issue might relate to TLS (Transport Layer Security) protocols. If your email server is using an older TLS version, it might be incompatible with iOS 18’s updated standards.

I deleted my Gmail account from my phone and reinstalled and it appears to work now…..

Have you given feedback to apple? So many of us with same problem everyone needs to send feedback so they fix it.
