Mail not working on iPhone after iOS 18 Update

Hi guys,


After updating my iPhone from iOS 17.7 to 18, I encountered an error with my work email. It's showing "IMAP server is not responding."Our mail server uses TLS version 1.1. Does iOS 18 support this version? Can you confirm?

I’d get the server to TLSv1.2 and with forward security configured minimally, and test again.


IMAP (read, receive) and ESMTP (send) are separate network services, so check both.


There are various ways to check the TLS and cipher offers by a server, and curl and testssl among those,:

Also check the IMAP and ESMTP server logs for any failure-relevant details that might be included there.

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 !!!

So, I have had three 90 minute sessions with Apple support, initially on-line then at the Genius Bar and then next level support by phone from the Bar. None acknowledged an issue with iOS 18 and ended up blaming my ISP. I have deleted and re-entered the email account maybe 20 times under “support” or “””genius””” direction. I want to see an acknowledgment that iOS18.?.? Fixes this issue before investing mote of my life in this vexing and apparently trivial issue. Quite appalling effort from Apple.

Mail from the same Mail server works on my other devices using a different mail client without all the Voodoo and secret decoder rings. Apple just needs to look at it so they can fix their bug. This is their own message board, so they should also be reading this thread. Maybe they're waiting for us to figure it out so they can fix it?

I do not think that this solves all our cases. Maybe some.

If that would be the answer (on the provider side and not on Apple side) then how do you explain the fact that I have two e-mail accounts with the same provider and only one has problems?

They are both configured in the same way, one functions with Apple Mail, but the other not.

I do not think that my provider needs to modify whatsoever. Moreover, the problematic account was not problematic before the update and is not problematic with Outlook or Spark.

I have. As I have two mail accounts with the same provider and only one has problems, Apple cannot say that the solution must come from the provider.

On the phone I was told that they are working in it. Should I believe them? But Even if I do not believe them, I have no other way than using another app and waiting.


I strongly believe that we need, all of us, to contact them. The more complains they have, the better for us. But we must not accept that they say that it is our or the provider’s mistake. We all have a tablet where our mail functions. We can all bring at least this as argument. It is not also very logical that so many mail accounts have problems just by updating the IOS. So if they tell you that it is the provider’s problem, it is up to you (to your arguments and your patience) to tell and insist that this is not the case and make them accept it.


I think that the issue has not yet reached the ‘press’. That would help us a lot, I think, as for the time being we are complaining between ourselves.

I did wait until 18.1 and STILL this issue persists. So now I have an essentially bricked iPad, since email is its primary use. I’ve been deleting accounts, adjusting settings, and re-adding them for 2 days now. Sadly, I’m used to this extreme inconvenience because I have to do this when mail server certificates change anyway since Apple doesn’t let you trust new mail server certificates. Unfortunately, adding accounts back doesn’t seem to fix this latest Apple-induced FAILURE.

I am so absolutely disgusted with Apple. I just received my brand new Iphone 16 pro max 1 T and mail doesn't work and nor does the share location map on my messages app for those who have shared their location with me. Works on my other devices. I have been an apple user since for decades. It's time for me to start looking else where. Almost $2000 for this device. Apple is not good!

WHOA…. This evening, my iPhone (18.1) started getting mail from my IMAP account. It started around 9:40 central time. It has so far updated and gotten new mail a couple times since — it seems like it is going really slow or delayed, but it IS grabbing it. I checked my iPad (also 18.1) and was NOT getting anything new from that account. The only thing I did different is that I had been on the phone with apple support to cancel an AppleCare renewal, and was searching my mail to find the agreement number.


So I tried searching mail in the IMAP account inbox on my iPad…. I thought, maybe that’s what changed something here? I mean, how could Apple suddenly “Fix this” remotely, right? (Well, maybe there are things they can silently update, who knows)


Then, about ten minutes ago (10:30 central), my iPad started getting and showing the new mail from that account also…

I am still unable to collect email on my iPhone whilst it works perfectly with identical settings on my MacBook. This is incredibly frustrating as I’m out and about a lot so rely on my phone for emails. I tried the slash in IMAP field but that hasn’t improved things for me. I’ve deleted and recreated my email accounts several times with no joy.


Seems to be taking a long time for Apple to resolve this. Beginning to lose faith in Apple and certainly wish I hadn’t updated iOS. Anyone know if there is a fix imminent?


Thanks

well, as of this morning neither the iPhone nor the iPad fetched any new mail since 10 PM last night.


so now it’s an an even stranger bug. Why’d it work momentarily? It’s back to nothing new despite that account getting about 60 new emails since then. None have appeared in the mail app.
