Mail not working after update iOS 18.1.1

After updating iOS to 18.1.1, the mail app is not working. It is totally malfunction and can’t receive nor send email. Start the mail app, it just pops up a white screen. I have tried to offload the app and reinstall it. It’s the same. When I hard reset the phone, it can pop up the mail account list but freezes. How do I fix it?

iPhone 14 Pro Max, iOS 18

My yahoo mail and iCloud are not working since upgrade to IOS 18.1.1 I’ve restarted phone, and no email is downloading! How do I fix without a complete reboot that will lose all my saved data?

One of my gmail accounts is not receiving emails on the iphone since update Thursday night. The second is. Has anyone found a solution? I have switched on and off many times, gone into settings and checked everything I was asked to check by Apple support and it still doesn't receive or send visibly - I received test email on my mac which receives all email as ever. Just not iphone since update. Any solutions?

*SOLUTION* This issue seems to be limited to accounts that were configured to use the IMAP protocol when they were created on the iPhone. Accounts using POP3 are not affected. Unfortunately there is no way to change an existing mail account from IMAP to POP3 so the only option is to create a new mail account on your iPhone using POP3. Way to go Apple! You become more and more like Microsoft every day!

I had the same problem right after the update and was able to fix my issue thanks to the IT department for the company I work for. Please give the following a try?


1.      Open Settings on your iPhone.


2.      Navigate to Apps > Mail > Mail Accounts.


3.      Select the affected email account.


4.      Tap Account Settings, then Advanced.


5.      In the Incoming Settings section, locate the IMAP Path Prefix field.


6.      If it's empty or shows a greyed-out "/", retype the forward slash ("/") so it turns white.


7.      Tap Done to save the changes.


8.      Close and reopen the Mail app to see if the issue is resolved.


Good luck!!!

I know that, but I don’t want to make such a backup because it’s already more than 500GB. Then I need to find a drive to store the data first. Moreover, I’ve done this before. After that, all the data are messed up. Some data of some apps are still missing. So it’s rather troublesome. Are there any methods to make it work? Or do I downgrade the iOS to 17? Or are there methods to reinstall the mail app only?
