Yahoo email not working in mail app with iOS 11

I have 2 yahoo accounts - one works FINE the other - my main account - doesn't set up same on both, and compared to my sons as he has no issue and settings are the same. Still NOT working after weeks. FRUSTRATED!!

Mine too I have to delete yahoo mail and restart phone and enter email in again but it only lasts an hour before it stops working again . Just happened since 11.2.2 update . The Yahoo app works but isn’t the best

Apple need to resolve

Experiencing this issues as well! Started about a week ago for me.

Using an alternative app or deleting/re-adding my account in iOS settings have been the only steps that have worked for me. Hoping for a permanent fix soon!

Based on what i see, this cannot be a yahoo issue. Not only my yahoo webmail works fine, it also works fine on my iPad. Also I do not any Pop Account. This is a iPhone issue.

Spoke to Apple Support - only thing they could suggest is setup my phone a New (not restore from backup) and then see what happens. I did not agree to setup a New (of course) but reset my phone from backup. Lets see how many days till the issue recurs (I hope not).

(Something is wrong with this site itself - the editor does not let me select/highlight - using Edge)

Using Yahoo Mail app is not exactly a great solution. I had earlier used the app (just to try it) - did not have great experience. Ideally need a single app to see all my mails - that is what Apple app does. But we are having issues with that. In any case my problems are only sporadic - once every week or so - lasts few hours to a day.

I dont think it's a Yahoo issue as I have the same issue with my Gmail account. iCloud and Outlook both work fine but Yahoo and Gmail dont. The mails from them seem to come through along with an iCloud or Outlook mail. When they're pushed through it seems to force the phone to poll all accounts and drags the others with it.

I agree that it's not a great solution. I have an Exchange account and a Gmail account so it wouldn't work for me. However, my wife only has the Yahoo account, her needs are simple, and the Yahoo app is perfect for her (until the problem is fixed).

I had a lot of problems with Gmail on my Mac some time ago and, after searching forums for the answer, found that I needed to turn off "store drafts on server." After I did that it was fine. You might try checking that out. In addition there are some issues with two-factor authentication with Gmail that you might need to resolve.

And as I mentioned above, I think there is an issue with security between Apple Mail and Yahoo. Here's the message I received from Yahoo on my "recovery" email for my wife's Yahoo account after I deleted her Yahoo account and then tried to set it up "manually on her iPhone:"

"Your account is currently not enabled to sign in from apps that do not meet modern security standards (ex. Older versions of mail and calendar apps such as Outlook). As a result, we prevented a sign in to your Yahoo account.

We strongly recommend that you switch to Yahoo's apps such as Yahoo Mail on desktop and mobile and remove your account from all other less secure apps.

If you still want to use an app that uses less secure sign in, go to https://login.yahoo.com/account/security#other-apps and turn on "Allow apps that use less secure sign in". This is not recommended and may leave your account more vulnerable to compromise. To learn more, please visit our help page: https://help.yahoo.com/kb/SLN27791.html."

Whether it is Apple or Yahoo's configuration problems, it AT&T's problem, too. I did, however, find the following website, which indicates that it is Yahoo's servers that are, presently, and have been down for the past week, and, intermittently, it seems, since the merger of AT&T and Yahoo. In my case, the incoming mail is painfully slow; but the critical problem is that my Mail program on Mac OS X puts mail I send in the "Sent" folder, but it doesn't go anywhere - not even visible on webmail in "Sent" or anywhere else. Also had strange things showing up in my "Spam" folder (like email from me to me!). Check out this "down detector" and read the comments. This is ridiculous, and costly; and I will not let this sleeping dog lie without contacting every government agency and administrative offices until it is resolved. I also think we should be credited on our bills. Hope all is resolved very soon. http://downdetector.com/status/yahoo-mail/news/173995-problems-at-yahoo-mail-5

The issues with the Apple iPhone App are making it impossible to use.

Shifting to the Yhooo Mail App. At first glance it is clear it is not very user friendly and lacks features - Single landing page for all accounts, calendar sync- just to name a couple of obvious ones. Have not turned on notifications - I think it would popup a alert on every email. That would be annoying.

But if it works better on the core basic feature - deliver email reliably/timely - that would be the choice.

It is a shame that basic email itself is becoming a problem.

I recently installed the Outlook mail app and it seems to have a nice, clean interface and is, of course, Exchange friendly as well. In fact, it reminds me a lot of Apple Mail. Perhaps Outlook would be better choice than the Yahoo app. Note, however, that I have not used it extensively since it's my wife that has the Yahoo account. One thing I like about the Yahoo app is that you can "mark as spam" fairly easily with it. My gmail account almost NEVER receives spam, but my wife gets tons of spam in her Yahoo mail.

Per the yahoo support page you need to do the opposite of what is being recommended by @oasisg9.

Yahoo recommendation is delete Account in Apple App and add it back.

Yahoo actually now requires Account Key to be setup for Apple App. If you delete your yahoo Acct and try to add it back in Apple app - it would force you to setup Account Key. I have done this now lets see how it works.

Earlier I did not have Account Key neither for Apple App or my Ymail account itself - it did not work. So lets see now.

That is exactly what I said dude. Delete your yahoo mail account (in the apple app) on your iphone.

You are mistaken that Yahoo requires an account key to be set up for the apple app. I had an account key previously that was active, and could not access the option that says 'Allow Apps That Use Less Secure Sign In,' so I had to delete my account key in order to disable that option. Like I said, I just added my yahoo account back through the Apple Mail app on my iphone, AFTER DELETING MY YAHOO ACCOUNT KEY, and not only did it let me, but everything works fine and I can get my yahoo mail on my apple mail app now without any problems.

I spent a long time reading through this thread and everyone's comments, and actually took a few hours to research this problem through trial and error, until I isolated the issue and found an acceptable solution that works. I took additional time to share my results with everyone on this thread, since so many people were having the same issue, so I would appreciate it if you wouldn't mislead other people and discount my post with invalid information when you haven't done the proper research; otherwise you would know that what I posted is true and works.

My husband had the problem on his iphone 6 as well and was very frustrated; it started before the iOS update. He deleted and re-uploaded Yahoo, and it also updated the iOS to 11. Still no inbox updating. Today I asked him to check his spam file after reading some of the other comments. It was indeed populated. When he went back to his inbox it updated!

I've done all you suggested above, still not working😟 Can send mail no problem, when I check mail from the Apple app it downloads the mail, but doesn't show. Can get mail on computer no problem. This is frustrating!
