Mail not working on iPhone after iOS 18 Update

Hi all, I Just check my Emails Securityfile Mail on iPhone 11 Mail/app IOS18 and it's no errors but it won't synchronize all my folders and emails. so yeah it is bug, don't panics hold your buts tight, they will fix it.

Thank you for your sharing information. I am also very confused by this issue. On some devices, recreating the account resolved the problem, but on others, even after recreating the account, the issue persists. Additionally, there are devices that can connect to Gmail, while others cannot.

I’ve deleted and reinstalled once, with no improvement. I don’t fancy doing it again and again: I’ve just made Outlook my default mail app. It’s vastly superior and works with both my Yahoo and Gmail accounts. Bye bye, iOS Mail!

My issue with a little different. Since the upgrade I was getting a “connect , just updated” message constantly but was not able to get any new emails. I began deleting each email app and reinstalling it. Until I hit the Gmail app. After reinstalling it, all issues got resolved.

I have this exact issue and adding a forward slash (/) does nothing. This is a bug, as Polkamatic stated, and I want to know when this will be fixed.

My biggest issue is that it only happens with one of my Gmail accounts. I don't even know how that is possible.

Do not get your hopes up...

Did everything you described in your message

The issue is still there.

Afterwards I rolled back to ios 18 as I found some more things that I did not like.

But who knows, maybe in the public release they will have this solved but I already gave up on hoping....

You are lucky. I have contacted my mail provider and they cannot help much. Moreover they do not really understand why from the two mail accounts I have with them, only one has problems. The other one is functioning correctly. I will try to contact Apple by phone and I will post here their ‘advice’.

Emails cannot be retrieved after iOS update 18 and Apple sent iOS 18.1 and now I can send or retrieve. Absolute garbage!!! I can only use email when connected to wifi. I’m on the road 90% if the time. Furious!

Are you sure you didn't already have a forward slash there? In my case, the gray forward slash isn't an editable character. You can't type next to it. When you insert a new slash, it just replaces the gray one.

No change on 18.1b3.

This is unbelievable. emails not working on extremely expensive iOS devices.

Same here. No joy on iOS or iPadOS.

rather infuriating that such simple and necessary functionality was screwed up.

Hello, somehow, self-signed certificates don't work anymore (even though they could be trusted before and most likely adhere to the requirements).

I was able to provide MDM payload with a Step-CA root certificate, its intermediate certificate and the signed certificate of the mailserver - it seems to be important that the chain of trust be completely working, including working DNS and alt name of the host. With iOS18.0.1, i have my mail back working.

If there are other bugs (like Prefixes on IMAP paths) i don't know, but i did not experience them and by looking in the SMTP/IMAP server logs, i was confirmed enough that TLS did not work.

Correct. The problems were created with very much tightened email security measures (need for which was prompted by nefarious international hackers) unevenly implemented across programmers and service providers. I’m sure they are still working their way through the necessary fixes but it is best for everyone notify their own relevant providers/companies.

This is driving me nuts. Bug is still there in 8.1b6. I submitted feedback on Apple’s main feedback page. I also shared feedback on Apple’s feedback app on the 18.1b6 device. This is beyond infuriating

I was able to temporarily fix my email issue. Instead of creating my email accounts as IMAP, I made them POP3 accounts.

It sucks because my emails won’t sync with my Mac email but at least I’m getting mail on my phone.

I hope Apple will get this fixed soon because there are many people having issues with the Mail app since iOS 18 was released.

It seems that after EVERY UPDATE there is a new “glitch”. (I’m scared to even get an update now!)

I can access my different email accounts individually but when I try “All I boxes” all I get is my screen flashing and it keeps saying “connecting” at the bottom - sometimes for more than an hour - I’VE TRIED!!!

Im technologically challenged so hopefully there is a simple walk through soon on how to actually fix it.

My only workaround is looking at each individual email - SO FRUSTRATING !!!
