iOS 18 iCloud mail does not sync with other devices; all other mail accounts work fine

Still wouldn't sync, googling led me to the following advice that did work:

On all devices:

1) Settings->Apps->Facetime: Turn OFF

2) Settings->Apps->Messages: Turn OFF

3) Reboot devices (Vol up, Vol dn, Hold Power until you see the Apple Logo)

4) Settings->Apps->Facetime: Turn ON

5) Settings->Apps->Messages: Turn ON

I was able to fix this by logging out of my iCloud account on my iPad and then logging back in using my phone.

On iPad: Settings-> Your Name -> Sign Out (bottom of Screen)

Then I went back in and resigned in and chose the option to “use a nearby device” and signed in from my iPhone.

I was only trying to sync these two devices so I suspect you’d have to do the same on your other devices as well.

My issue was the same for 3 email accounts: iCloud mail and Yahoo mail all nested in the Apple Mail App. Just got off the call with the support agend and we tried resetting the network settings, pushing email manually, deselecting the iCloud email and selecting again. None of which worked.

The solution (which worked in my case), was to:

1. Reinstall the email app (remove and install again)
2. Go to inbox, and next to the 'Select' Button, click on the 3 dots
3. Select the List View

Hope that helps to others.

My Calendars, Contacts and Messages were not syncing after update to iOS18

Updating had turned off syncing.

Settings->iCloud->Saved to iCloud[See All], and turned them all back on.

My mail is not syncing. When I delete an email on my phone, it still appears on my computer. But it works if I delete on my computer, then it is deleted on my phone. I've tried restarting my computer. Turning my phone on and off. Checking to make sure everything is turned on and I'm signed in on all devices.

So something on my computer email is not syncing with my other devices. What else can I do? HELP!!

I am having a problem with my email as well. I just purchased my iPad and upgraded to iOS 18, and my email will not sync properly, nor with my texts. My email will show, let’s say 12 emails that are new, which matches my phone, but the iPad will not populate the emails. Some texts come through, but not many - I can’t figure our why it is so random.

Help!

Same for me too. My iPad OS mail isn’t syncing either. Really frustrating. How long before Apple fixes this with either the mail server or update to iOS & iPAD OS. Inexcusable. This complaint has been going on since Sept ?!?!

Apple, you’re better than this.

Add me to the list of mail and messages not syncing across iPhone and MacBook Pro. All are updated to latest OSes but it’s been going on with previous versions as well. Tried some of fixes suggested but ongoing issue. Frustrating. Com’on Apple stop breaking things!

This problem has been going on for months and Apple has yet to fix it. Prior to iOS 18, Mail synced seamlessly between my Macbook Pro, iPad and iPhone. Now it's just a mess. Pretty disgraceful if you ask me..!!

Same problem for me. iPhone, Mac and iPad all running the latest OSes released and iCloud mail is not in sync.

Apple, please stop breaking things...

I’m having the same issue exactly.

My iCloud Photos won’t work since updating to 18 .

Just to make sure, this advice helped you with iCloud Mail???

Just tried that to no avail. Crazy that it's been months and there's still no fix to this issue!!
