Yahoo email not working in mail app with iOS 11

Was anyone having this problem using Yahoo Mail Pro? I signed up for it like 10 years ago and kept forgetting to cancel it, but once i cancelled it, it seems I my mail barely updates and it takes forever to get messages. I guess i lost the push function when i cancelled pro, but not sure if this is the root cause of my messages not showing up.

My email started malfunctioning about a week ago so around 1 December. I’m curious if the purchase of Yahoo by Verizon has anything to do with it. Being devils advocate here. It’s seem to start after that acquisition was approved and perhaps there’s been some server changes. I don’t think Verizon would want to fight with Apple but rather maybe changing the addresses of the servers. At any rate, because Verizon also have cell phone service it would be an all parties best interest that they work this out and quickly.

I have the same problem. There is no problem receiving yahoo mail on my 4th generation iPad. No problem with my android phone either. Just with the new iPad Pro running the latest version of iOS 11. I met with Best Buy Geek Squad on 12/15/17 to discuss the problem. They told me that it was a known problem and that Apple and Yahoo were working to resolve it. I hope they find a fix soon because this is really not acceptable.

If it is worth something, I started having the same issue after updating to ios 11.

Must mention that around the same dates I added a second yahoo address, for what another user says maybe ios does not know how to manage 2 accounts in yahoo.

I was having the same issue. Went into account security settings in my yahoo account (on the browser version) and clicked to “allow third party apps”. Then reinstalled on my phone and worked perfect.

In iPhone settings all I did was the following:

Accounts & Passwords / Yahoo! / Account / SMTP / Add Server / Host Name

Type in 'smtp.mail.yahoo.com' and hit 'Save'. Didn't require to enter a username or password. It will verify for fifteen to twenty seconds and the result was immediate, i.e. emails downloading to my inbox with no issue.

Thanks!

Just followed your instructions, seems to be OK now, will keep an eye open to validate.

In case of having the same issue will try as suggested by another user, allow 3rd party apps in tge Yahoo email settings.

Thanks! Again.

Yeah, that works for a little while then it stops working. It says “checking mail” but just spins. It’s bull crap that this is happening. It’s probably yahoos way of forcing us to use their app. I’m just going to switch to gmail. Either that or it’s apples way of forcing anyone with an older phone to upgrade.

I am having the same issue with Yahoo email, except that I am still on iOS 10.3.3. This started about a week ago. There are many people complaining about this on the Yahoo help community forums, though the moderators are marking the threads as solved despite acknowledging that their "engineers" are working on it. If I delete the Yahoo account in iOS mail settings and set up a new account, it works for a while before invariably failing to download emails again a few hours later. This is very frustrating.

Yes this is exactly what happens. And I’ve done all troubleshooting except a totally clean wipe and restore from default on the iPhone to see if that fixes. Probably not though.

I think I’ve found a workaround for the problem. Under “Accounts and Passwords” go to “Fetch” and change from Automatically to Manual. I did that about 24 hours ago and so far, every time I’ve opened the mail app, my new mail appeared within a few seconds. I can live with that until the problem gets a proper fix. Apple, Yahoo. Come on!

Yea 1 week ago is about when it started for me when I logged onto my laptop and saw 17 unread (important) emails. No idea what happened here but does not seem iOS related, I had no changes on my phone prior to this not refreshing. I did the imap/pop thing 2-3 times, deleted accounts 2-3 times, reset phone, updated software and same issue. The imap manual setup can get it to work for 2-3 hours then it fails again as noted. Really frustrating. I hate yahoo but I am pretty committed to it after using for 10+ years. Anyways I set up a forwarding to my gmail from yahoo and it works great, I'll be using that feature as I slowly change over everything to my gmail over the next year or so.

TL:DR - yahoo ***** switch to gmail and forward your yahoo to your new gmail in the meantime.

This seemed to have worked for me (for the time being):

Open the Yahoo mail webpage from your desktop. Go to Account Info (click on the gear icon/help in the upper right hand corner and Account Info is at the bottome of the popup menu). Once you're at the Account Info page, on the left hand side click on Account Security. Turn off "Allow apps that use less secure sign in." If it's already off, turn it on and see if it makes a difference. Finally, for good measure, remove your Yahoo mail account from your iPhone and reinstall using the default settings.

This has allowed me to fetch email on my iPhone for about 6 hours now, the longest stretch in days. We'll see if it still works tomorrow...

POSSIBLE SOLUTION... I have this issue currently and for at least the past few weeks. Based off of one of the other comments I decided to try and turn OFF two-factor authentication. So far this is working, although I'd prefer it work with two-factor on.

I find that if you log into yahoo mail through a browser, all missing emails start to appear on the iPhone. Once you log out and try to let the iPhone go solo, it's just a matter of days until you notice that you're not getting email anymore. And the vicious cycle starts again.
