Yahoo email not working in mail app with iOS 11

My email is also having issues.

I’m on 11.2.5 and currently if I login to yahoo’s website I have 51 unread emails, however, on the mail app I have no unread emails. Every 3 or 4 days I’ll get some emails but I don’t get all of them. I also have 2 different gmail emails on here. They seem to be working fine.

For yahoo mail not working on iPhone, especially in iOS 11, there are different solutions depending on what kind of situation you are in, but you can check this tutorial to find the possible methods:

[Solved] How to Fix Yahoo Mail not Working on iPhone with iOS 11 >

Thanks for the support. I have tried adding and removing a few times. I have also changed my yahoo password. I guess I’m just going to download the yahoo app and wait for Apple to update the software

I have also uninstalled/reinstalled several times. I have contacted Apple support that told me uninstall/reinstall...didn't word so advised contacting yahoo to reboot the server for the affected account. My child has the same issue. HOW do I contact yahoo support to get the served rebooted is what I would like to know. I have already wasted soooo much time on this nonsense.

Thank you for your advice. I have tried all of those steps multiple times. Yahoo mail app seems to be the only thing that works. It’s sctuallu not that bad and it’s nice to get the emails as they come in.

Alright I think I figured out how to fix this issue.

You have to login to your Yahoo account from a browser then select your name, Account Info and Account Security.

You should see a "manage app passwords". Add iPhone mail and follow the prompts.

I had to remove and recreate the yahoo mail account but at the end it worked.

The reason for this is that now Yahoo has tighten their security requirements and wants you to have more secure passwords. By following the above steps you are basically performing a two-step authentication and using a random password to access your account from your iPhone.

Hope this helps someone.

All this on and on round and round seems to be utter nonsense. No other way to describe it.

Yahoo is trying to do its own 2-factor and app validation, parallel Apple is trying to do its own. None of them are solving the problem.

I originally tried setting up 'Secure Key' for my iPhone App - (as originally suggested by Yahoo) - did not help at all.

Now this new Yahoo thing "Create App Specific Password". You cant even do this, only way to do this is you have to delete the Yahoo Account in the iPhone App and then try recreate it (there is no other way to update the password). The directions state 'update password'.

I went this route - now the account does not get added in the iPhone App - as it says account already exists. I don't know if it (mistakenly) referring to the acct I just deleted or to the Account I have with the Yahoo Mail app (I have this). Also it asks for 'Secure Key' and not the "App Specific Password" which I had just created.

So now I am left without yahoo account on my iPhone App. Maybe (in all likelihood) this was the ultimate objective of Yahoo and had to go thru all this to achieve their goal.

What utter nonsense.

This whole thing about additional security is total crap, either your mail should be working or not - nothing in between - sometime working sometimes not.

I totally agree with you is just nonsense.

I have to retrace my earlier comment from yesterday when I said that I thought I found a solution... well, is not true. This morning my Yahoo emails are not coming in again so the App password doesn't fix it!.

you should be able to recreate your yahoo account after you restart your phone.

I am calling Apple support again now.

Thanks for your detailed fix description. You are probably NOT on iOS 11. The setup screen looks very different. IMAP settings are rejected. I was able to select POP tab in the settings and used a pop server. This allowed me to set up Yahoo! on iPad. Yes, I have enabled 'Allow apps that use less secure sign-in'.

Still, it's a shame that a built-in Yahoo! option does not work. I hate to install a separate app for each email that I use so Gmail or Yahoo!, forgive me, I am not putting your apps on my iPad.

I been having same problem with my Yahoo via mail configured on my phone. when I use apple mail on iPhone 7 with iOS 11.2.5(15D60) yahoo email dose not work. It dose not download all my yahoo email. It shows there are mail and it’s downloading but nothing shows in my inbox. This is been going on for fast couple months and last two updates. I took it into apple store and they tell me I need to contact Yahoo.

I told them

It works fine on the computer and even using yahoo mail app. But Apple never think it’s their problem.

Thanks for posting this. When I log into my Yahoo account and go to Account Security, I do not have any options to manage app passwords. I only see a link to Change Password. Anyone else having this issue?

Hello,

I was able to work around using the IMAP option which is annoying if you have more than one yahoo email account. I decided to use the yahoo mail app (app store) until this issue has been resolved. I was able to add all of my yahoo accounts to the yahoo mail app with the option of adding my gmail accounts. I hope this helps.

Yahoo is my default email and I am unable to get mail in. I reset my phone, deleted and attempted to reload email that says I already have the account ughh I am my wits end on this one. I have had this email forever and it would be awful to have to start over.

I really wish people wouldn't post answers like the one just have. The instructions ARE NOT working for everyone and it would be much more helpful to those of us who are experiencing these issues if we had constructive feedback instead of responses like this.

Looks like yahoo has turned everything off right now to access their servers unless using their app. I’ve tried setting up imap thru iPhone mail manually, selecting the Yahoo! option, setting it up in iPhone outlook app and all I get is server unavailable or not responding. Very frustrating because I don’t want to use their app with annoying advertisements.
