“Had the same problems with imap

just installed 18.1.2 and problem solved”

sadly not for me.

Hi

Does anyone still have the problem

with IMAP accounts in the MAIL App,

I can't seem to solve it?

Yes, the problem remains.

it is an iOS/ipados 18.1 bug in the mail app.

Suggest you read pages 20-22 of this thread.

Looks like a relation to the email password for email Exchange. Possibly or probably the other mail

accounts.

ex:- try using your known password - get the unable to

verify account information.

18.1.1 seems to have fixed the problem. At least on my iPad.

I had to delete my email account and then add it back in again. Email sends and receives worked fine for two days and now are not working again.

Set up local DNS to point the external address to the IP address may solve your problem

That's bc bug only on IOS 18.

/ it Optional and will not fix issue.

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.

I also have the same problem on my iPAD with iOS 18.

My iPhone on 17.7 is going well.

The weirdest part is that I have 3 different account on the same mail server (just different username/password). 2 of them refuse to works (server is not responding) while the tird one works.

I tried to delete all the account from the mail app and recreate them ... same problem.

That appears to be central to this issue - previously iOS mail would notice when this email server’s certain rotated and its ask me to trust. 18 appears to be not asking but macOS is.

it makes me wonder what will happen to you when your server’s certificate renews - will you need to delete the account again and do it all over?

True, but why is the macOS mail app working fine?

Because macOS and iOS are NOT the same thing.

Exactly. Bug regressions like this recurring imap fetch failure get fixed in macOS releases.

Same problem. After upgrade to iOS 18, both iPad and iPhone cannot download e-mails from one of my business e-mail accounts. When I delete the account and re-add it, everything seems fine. In the last step of adding it, all input is acknowledged with a green check bar. Yet, the download of mail messages is not possible. Sending is no problem. Sometimes I am asked for a password; entering it makes no difference. I am hundred percent sure, that the password is correct. All other mail accounts (including other imap accounts) work just fine.

It is a business account that requires a domain name as part of the user name. Is it possible that this is the problem?

By the way, with my Macs on Sequoia all e-mail accounts work like a charm as well.

A fix is urgently needed. Otherwise, both iPhone and iPad are pretty much useless for me.

Thanks.

Same problem here. Mail does not download emails even though the credentials are correct and are accepted by the system. It is a professional Imap account. Problem only on ipad and iphone. On MacOs 15.0 it works perfectly. I tried any solution but it does not work. The same account with the same credentials on the same device works perfectly on Outlook...What a shame.
