Mail not working on iPhone after iOS 18 Update

Hi,

omg; thank you so much!!!!!

I have been going crazy for days as I kept on getting a message saying that my password is out of the bloom not correct. I changed it 3 times and checked and rechecked and no joy.

Strange, it worked fine for about 24h after an update and then my Hotmail password would not be recognised.

i did what you said and it worked beautifully.

thank you sooooooo much!!!!

I just purchased an iPhone 16 plus, however I cannot reply to my emails in Hotmail. It repeatedly says there is a problem. I took the iphone back to the store and they suggested using the outlook app (instead of the full web version), however this is insufficient for my work. They said Apple should be working on fixing the problem... I hope this is so, as I will have to revert back to my old Samsung 10+ until then. Note: my Samsung has been working beautifully for 9 years. I only bought a new iphone because I was having trouble sending files from my Samsung to my new MacBook. I am extremely unhappy about this situation. It is effecting my work, business and patience.

Yes mail not working (apple app that comes with the phone). Unbelievable that apple lets this kind of problem out the door. Its happened with some other releases too. Email is 50% of the reason I have ridiculously overpowered phone. And they’ve done nothing yet. Wonderful.

My issue is a bit difference. My iPhone Xs with IOS 18 gets emails. When I delete an email from my iMac inbox it deletes it from the iPhone inbox. All well and good. The email goes to trash on each device. When I delete the email from the iMac trash... it DOES NOT delete from the iPhone trash.

But if I delete from the iPhone trash it DOES delete it from the iMac.

I've tried everything... but can't figure it out.

(Note: I use Postbox on my iMac and the standard IOS mail app on the iPhone. )

I updated to iOS 18.0 at the weekend and same thing has happened keep getting the message saying my password is incorrect even though it’s 100 percent correct. Any ideas what to do to fix? Or will there be another update to fix if Apple are aware?

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.

Seems not, at least not for me…my issue is with 2 yahoo email accounts and I have the same issue as before. None of them automatically download emails. I sometimes get the badge next to the mail app but I still need to open the app and wait for it to refresh and download emails. Weird thing is that for 2 other exchange accounts it works as intended with fetch set at 15 minutes…really hoped the update would fix it but…

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....

Did everything you described in your message and on top upgraded ios to the next version (will just say it is not public yet in order not to get moderated and edited again) . The issue is still there.

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’.

Zimbra has a trivially-exploited security vulnerability, and (unpatched) Zimbra servers might not be stable:

I am not happy at all! I have purchased every iPhone since its birth. I have an IPad Pro and a a MacBook Pro. This issue with IOS 18 turned my work imap email on my iPhone and iPad in to bricks. I tried all of the proposed fixes in this thread! Come on Apple this is the best you can do in new software deployment? You should be ashamed! I am waiting for the fix! My imap email on both can send emails and I get green check marks on all systems go but can get my inbound emails! Really unhappy and frustrated

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!

This problem turns my nice new iPhone 16 with iOS 18.0.1 into a little (expensive) boat anchor. MacOS Mail continues to work fine , but the iOS Mail has screwed my email and deleted all mail before the update was applied, including from the ISP server. This is VERY DANGEROUS.
