Mail not working on iPhone after iOS 18 Update

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.

FIXED

This problem is with IMAP folders that have special charecter,

I had in mine "á" in one of the folders , I renamed the folder and just used non special chars.

Fixed the problem.

Others here might have SSL Cert problems, but that is a different problem.

I have checkd this on Server side and Client side , tested back and forward.

IMAPS accounts with no folders sync fine in IOS 18, thouse that have special chars will give you this error.

Also this error is very confusing since it points users in the wrong direction.

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

Same with my email. No longer can download mails on cellular network but can on wifi. It turned out that after updating to ios 18 several apps that were switced on cellular were off after the upgrade. So check to see if cellular switch is on

I'm not using an iPad, but, restarting my iPhone after deleting my Mail settings and then renewing it worked , as it did for others. Did you try that on your iPad? Just curious because the Mail problem wasn't the only issue I had with my phone.

Yes, I actually downloaded 18.0.1 first. It screwed everything up, including Mail. I was also locked out of my phone and took it into a Tech. I got Mail working as I mentioned above in this thread.

On 2 iOS devices I deleted the mail accounts, re-added them back, the mail (1000s of messages) downloaded just fine, but then after that no new email downloads and changes to the messages are not reflected back on the other mail clients.

iPad 18 and MacOS 15 mail work, but iOS 18 seems not to communicate with the server properly. Outlook works.

"Checking for Mail..." hangs. After the connection, the server is waiting for commands.

The server is Dovecot

Connection closed (IDLE running for 0.001 + waiting input for 119.863 secs, 2 B in + 10 B out, state=wait-input)

You really DO need to contact your relevant external (external to Apple) email service provider about the problem; for me it was a behind-the-scenes fix that Comcast did - at least on my Comcast email accounts - that permanently resolved it. If your provider’s customer service or tech support rep says they have no idea what you’re talking about tell them to escalate it in order to work it out with Apple. I made only 1 call to Comcast about it and was told they were aware of the problem and expected to have it resolved within 24 hours (which they did, although as I recall I found that I did have to delete and reinstall my Comcast email accounts within iOS mail to complete the fix at my end once Comcast completed their work on it).

THANK YOU for posting this. I DO SEE a greyed out “/“ and I’ve followed your very good step by step instructions (I’m technologically challenged).

Hopefully this will stop my “flashing” stuck emails when I’m trying to read all of my incoming mail.

(Apple probably has so many glitches they don’t know how to fix with every new update…)

It only worked for the first time after upgrading to 18.1. Now, I couldn’t fetch emails from my IMAP server again. Strangely, sometimes new mails were fetched time to time. Also, all the other folders synchronize flawlessly.

Imminent?

No, I do not think so. As I have an open ticket with Apple Support, they would have contacted me if they had any good news. At least, I want to believe that they would have done so.

I will try to ask them if they have any news next week.

Ok I have ios 18.1 just updated last night. I followed the path you listed above and all I have under advanced settings from top down is:

-a toggle for [Use SSL]

-Move deleted messages into: Deleted Mailbox or Archive Mailbox

-2 choices under S/MIME:

-[Sign] can choose either Yes or N

-[Encrypt by Default] can choose either Yes or No.

There is no field for IMAP Path Prefix under any of my mail settings.

I am as well, having trouble Sending mail using IOS 18 with the Safari App. With me,

every time I try to send an email, it “bounces back,” saying I have the wrong

forwarding address/to address, when I type that address in by hand. It is

very frustrating. The problem is with my iPad.

I have the same issue, my iphone is sending emails, saves email in sent folder on iphone, but not on imap server, so it is not shown on my other devices. Very frustrating. Have been on my email providers support and apple support for hours and still it is not working.
