My accounts in Mail app stopped to sync post update

Yo can do what you want - but that is not a login/connection issue.

simple developers faulted somewhere in code after login process. can see communication log from me in this thread - clearly seen that has been logged-in (ok), asked for folder statuses (ok). but not requested any from messages that are in Inbox (stuck in new "rotating of icon" = they indirectly saying "user need not more than new interface improvements in some rounded corners and so on" - that is tendence in app-development already many years exist).

I manage a few mail domains and several thousand customers.

We recommend that everyone download another Mail Client (e.g., Edison's E-Mail) from the App Store and use that. FInce the problem is solved, that's fine.

Hi,

I had a similar issue with my email disappearing from multiple accounts, and after troubleshooting, I discovered that the problem was related to my self-hosted IMAP mail service on Synology. After updating the SSL certificate, the issue was resolved, and all my emails reappeared. If you're using a self-hosted solution, I recommend checking your SSL certificate as well.

Hope this helps!

The Comcast (Xfinity) level 3 technician, a MacBook user, said that the problem is a synchronization issue. He said that there are YouTube videos explaining how to fix the problem by repeatedly setting up one’s client email account until you get lucky and the two systems synch. This can take many attempts. Until Apple releases the fix, using your ISP online email site is the only thing that can be done.

I’ve been facing this issue since updating to iOS 18. Has anyone found a resolution? The only workaround that seems to work is accessing iCloud Mail through a web browser, but the app itself fails to connect and gives a “Network Error (POSIX 61).”

Any suggestions would be appreciated!

If you can not receive iCloud mail, go to Settings/Your Name/iCloud/Mail/iCloud Mail, and make sure, that "Use on this iPhone" is enabled.

I did not run into any issues using my 3rd party mail accounts or iCloud Mail on my iPhone after the iOS 18 upgrade.

@ingo2711 if you are referring to my comment --

I have deleted the account 20 times. I deleted the Apple Mail app from the phone, reinstalled from the App Store. it didn't help.

my comment about 3rd party email -- is a 3rd email app called Email - Edison Mail (from the App Store) I set up my mail accounts in the app and everything works as it should.

BTW - I never had the iOS 18 beta.

The issue is with the Apple mail app.

I've never had the iOS18 Beta installed,

As mentioned before, you can use the iPhone Feedback link, selecting the iOS 18 version is not required, Apple seems still be updating the iOS 18 related help articles, and the list is not complete yet.

The more users do this, the more attention will this issue get, when Apple techs go through the Feedback reports.

Feedback - iPhone - Apple

I have just installed iOS18.0.1 and the problem persist.

3 WEEKS without syncing mails on my iPhone.

How much AI is required to fix a sync issue with the mail app???

Hi,

I am also expriencing these issues with Apple Mail App in iOS 18. Apparently mails are not displayed on iPhone 15 pro and iPad Air (M1). The app sometimes shows a 'Network error (POSIX 96)' error message, but also states a latest update timestamp - but no (new) mails displayed.

I have tried the following:

• Restart Mail app
• Restart device
• Reset network settings
• Uninstall Mail App -> Restart device -> install Mail App

None of the above has remediated the issue.

Sending Mail does work though.

Using the mail account with e.g. Outlook works.

Mail works under Mac OS Sequoia (Apple mail app).

Please fix the Apple mail app for iPhone and iPad!

Cheers,

Martin

my mail hasn't been working for 2 months. since installing beta I've had huge problems with iPhone 15 pro.

Go to apple.com/feedback and sent in a Bug Report. It's the best we can do right now.

You can not choose IOS18 as operating system, but it's not mandatory, so just write it in your feedback.

My email wont download on ohone either! Ios18

Disabling SSL is not recommended, as it makes your iPhone browsing less secure. Your data can be intercepted more easily on unsafe sites.

Same problem here with Cyrus 2.4.17.
