Mail not working on iPhone after iOS 18 Update

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

My (hopefully temporary) workaround has been to use the Gmail app to sign in with my non Gmail account. At least I know I can reliably access my email. Seems to work better than the Apple mail app too.

It's been 2,5 months now and this problem still isn't fixed by Apple. I am experiencing the same problem as everyone else since the update to iOS 18 and the updated iOS 18.1.1 did not fix this problem either. Both my iPhones and iPad have this problem. My MacBook pro doesn't weirdly enough (old one, MacOS 13.7.1). And I can send mail from the mail program just like others but I can not receive it. Very annoying.

My girlfriend is not updating her iPhone to iOS 18 because of this problem and I wish I hadn't either... I normally never work on my old MacBook pro but since this big mistake of Apple in iOS18 I am forced to read and reply my e-mail on my old computer again. Bah.

Does anyone have a tip for a better mail-program than Mail that works on iPhone, iPad and on a MacBook?

If you go to your email, you can select one of them and instead of the big PRIMARY email, click on on 3 dots and select "list view" instead of "categories"and you can then see all your incoming emails. This was a simple fix for me as I have about 6 different email accounts on my phone.

This did not work for me. IMHO we should not have to go through all these technical acrobatics for the Mail app to work properly.

Apple needs to fix this bug. This was caused by their update to iOS18.

Unfortunately, I can confirm that update 18.2.1 still doesn't fix the synchronization problem with some IMAP servers. And all the martingales and miracle recipes read here and there change nothing. As a reminder, and I've checked again, synchronization with an iPhone running iOS 17 works perfectly.

What is Apple doing despite thousands of complaints to customer services all over the world?

It's totally crazy!

Apple needs to explain what is going on. My isp is not going to act just based on a user complaining about mail. The only client that is broken is IOS 18 mail. If Apple knows what server feature they are trying to use which does not work right with all servers provide an option to disable it! Today my IOS mail became totally dysfunctional. Other days it is fine. When it’s dysfunctional all other forms of mail clients work fine.

I deleted my email account that is not working from my iPhone 14, did a shutdown/restart, updated to iOS 18.2.1, re-added the email account to the mail app... and it still will not download mail. When will this get fixed? Is there any work around to get this to work? I've tried SSL/no SSL, I added the "/" to the IMAP Path Prefix. Nothing is working! This is very disappointing to say the least. Let's go Apple!! Fix this bug!!

Thank you. That was the discussion I meant to reference but could not find. It seems to me that Apple should provide a fall back to disable pipelining. Highly likely this is the problem I see on occasion where it spins around making no progress. Likely imap commands have been discarded.

I have no idea what sort of mail server code Comcast runs and I suspect they would not divulge that to me if I asked. That is why it’s a hard issue for an end user to pursue.

you can bet though that if a large company like Comcast is having trouble there are many frustrated users out there. The problem will only get worse as new phones are purchased and /or old phones are upgraded to iOS 18.

there is not even the slightest doubt in my mind that this problem started with iOS 18.

Most people are not having a problem with Mail so it is either unrelated to the upgrade or the result of an uncommon confluence of circumstances. Or, most likely, there are a number of different problems that people are all ascribing to the same cause. Regardless, it's not something that Apple is going to "explain."

If you want help from Apple, you will need to contact them directly.

Is there a manual way to install that update? I don’t see it anywhere

Hey, are you still using in 2024 hotmail ???? LOL Try Securityfile Mail NO ads NO phone number No spam!

The forward slash solution does not work for me. When will Apple fix this issue?

Please stop spamming this, we all know you are hired to say this over and over again, you are not helping this thread in any way…

iOS 18.0.1 did not fix my mail issue.
