iphone email app not working following 26.2 update

Make sure, if there is the option, that the account is set to push mail.

Your troubleshooting is good, and the only other possibility I can think of is that you have a VPN installed. UK government meddling tempted many if us to install VPN, lord forbid a free VPN.

Check Settings, General, VPN & device mgmt.

I’m not sure if this will help you, but this is what fixed it for me. It seems that when it was loading my messages it would get hung up on an old message. I either deleted that old message or put it in a folder and then the email started syncing again. I had to do that for several messages and now it has worked well for the past couple of weeks.

Me too. I called Apple. Tried all kinds of things and nothing worked. Guy told me it's a bug and will have to wait for an update to fix it. Works fine in the Outlook app. Pretty bad when Micro$oft works smoothly and the Mail app stumbles.

Mine resolved itself after I began deleting messages that seemed to hang up. For example, I had a message from 2019. I deleted that message and all the email started loading. Next, there was a message from 2022. After deleting that message all seems to be well. I have no idea why and it is completely ridiculous, but here we are.

Same thing, the update broke the email account I use for work. I can receive messages but it won’t send. Had to resort to using the Gmail app and it works but I just don’t like it nearly as much. Hoping they can get this fixed soon. No VPN here and all settings are correct.

I'm having the same issue and I don't have a VPN. I've done everything I know to do. I've deleted the account and readded it. I've deleted the mail app and then added it again. I've checked every setting. My mail on my Mac is fine but the mobile mail on my ipad and iphone are not working at all. The strange thing is that my ipad updated and the mail worked fine. It wasn't until the phone updated to 26.2 that the email on both stopped working.

I’m having similar problems with Mail app on my iPhone 15 pro after updating to IOS 26.2.1. Deleted and reloaded accounts, reset network settings, deleted and reloaded apps and called Apple and spent an hour on the phone doing exactly what I had already done, only to be told (1) I’m out of storage (I’m not), (2) it’s a problem connecting to Gmail so I should call Gmail (it isn’t). I reiterated that problem occurred after updating and none of my mail accounts are appearing or behaving as they should. But no help over the phone. I have an appt at the store later this week.

Same here. Then it didn't develop any more issues; yet. Not sure if it was the latest update but all is well again. The Apple Mail client/app has been plagued with issues for years. I like the interface and Thunderbird works quite well as a substitute.

I'm afraid iOs26 has done that to a lot or VPNS. As you paid for it, check the provider for updates, or at least let them know.

A family member of mine just bought Nord VPN against my advice!

Same. I’m now using outlook instead of apple mail. Ridiculous. 😤

Yes, same here. Only one random message would show. Frankly, I gave up. Then I checked several days ago and all is well. For now, anyway...
