Mail not working on iPhone after iOS 18 Update

This thread does not make encouraging reading and is filling up my inbox with far too many emails. I'll just stick with Outlook for my Yahoo and Gmail accounts, and unsubscribe from the thread.

Bye, everyone!

I have discovered something that is by far not a fix, but maybe it points to the root of the issue (at least for me). Seems that when on Wi-Fi connection and while charging, the e-mails are being fetched properly (for yahoo accounts) as per the fetch interval (15 minutes). I checked if I have some kind of restrictions for background app refresh for the native email app, but there are none (as there were none on ios 17. Moreover the Maill app is not even present in the list of apps that can be forced not to sync in the background and on top of that I have all enabled in that list) so I guess that is the issue that needs fixed (for me at least). The app thinks it has some kind of limitation like low power mode or something and it only fetches at 15 minutes intervals while charging and on Wi-Fi....hope this gets fixed...

I am having the same issue. After upgrading to iOS 18, I am no longer able to receive emails to my Inbox. Interestingly enough, I do get receive mail in my Junk folder, and am able to send email. I just cannot receive email to my Inbox. I hope Apple fixes this soon.

No, you are trying to financially benefit from your spammy posts that do not in any way address the problem.

The service you keep promoting, Securityfile, is a rinkydink operation at which you are programmer, tester, etc. – that's what your profile said yesterday, before you deceptively changed it. Moreover, I personally would be concerned about its safety, given that I can't find any evidence of anyone using it, reviews, or anything to give me any comfort that it is even on the level.

Please stop. Your posts are unhelpful noise.

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.

I did contact my non-Apple mail provider. This is also something Apple asks you to do. As I have already written, I have two e-mail accounts with the same provider. But the second one (which has the same configuration, apart of course the name and the password) has no problem! This is the most weird part of the issue.

It is for sure a problem of the app. In the « advanced settings » of the incoming server: at the top you have the possibility to set the folders of the mails. Well, with my problematic account I do not have the possibility to choose the folder of the sent emails. The only possible choice is… my Phone!!!

There is another very strange thing. We can all send e-mails from these problematic accounts; but where are these sent emails stored??? I cannot find them! They are nowhere.

Anyway. Now I have both Outlook and Spark installed and of course not the ‘Insecurity Mail’ as I cannot carry my laptop in the forest.

Next update: next Tuesday (Unless I have something to report before)

I have a hunch - does the working account have far fewer messages in it?

It has occurred to me that (while it should not make a difference) this may be the reason why some people have this problem and others don't. One thing I have noticed is that I only have this problem in my very full inbox. If I delete a bunch of items from a subfolder (using mail on my mac) that folder updates instantly on my phone, even while it is struggling to receive mail into my inbox.

Thanks! My Inbox is not that full, rather empty. These are my private mail accounts and I clean them systematically and transfer many items to a pst folder. (I am always afraid that even the best server can break down and hoping that one of my backups will survive)

Do you have it installed on your device? I’m asking because I had a previous version and the mail was still not working properly so I downgraded to the official one back. If so, which version do you have?

Maybe it fixes it for some people, but not for everyone. I have tried the current and previous releases.

I did this, but still had the same issue. It turned out to just be my outlook account that was causing the issue. When I deleted that account the email app stopped constantly trying to reconnect. When I re-added my outlook account I started having the same issue again.

edit: this wound up not being true. It only seemed like outlook was causing the issue. It started constantly refreshing again.

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.

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.

Is not only this. I am having issues with iCloud mail services too (yes - that is correct - apple icloud service mail and mail app : ). On Mac all folders being synced correctly, however on iphone some subfolders, mails are dissapearing - so there is a clear bug with mail app after IOS 18 upgrade.

Problem you mentioned with certs they had for ages and they never fixed (this was since 2011). After each setup I had to recreate mail accounts (imagine this doing for multiple business and family accounts - for every family member after every IOS upgrade). Is not funny Apple! Your support useless. Every time I am trying to explain this issue to tech guys I am being ignored or they admitting is a bug and telling me that not much can be done.

Same! I absolutely did not want to update this soon. I typically wait until they have worked out the kinks, but given that I was in the hurricane path, I wanted to download it so that I could have the satellite. Siiggghhh
