Yahoo! mail stopped working with Yosemite

For the second time in two weeks, my Yahoo! account is completely unresponsive on my Mac (Apple Mail). Works fine on iPad and iPhone. Gmail and .me accounts work on the Mac, just not Yahoo! I've tried most of the suggestions in these posts, including deleting and reinstalling (took a couple of days!) Any new ideas? I think last time it just decided to finally work, and the delete and reinstall was not necessary. At any rate, I don't want to be out of commission for that long.

This has been broken for at least 48 hours now.

Dorothy, I've been having similar problem the past two weeks. This worked for me: Remove your Yahoo! account from System Preferences, Internet Accounts. Restart your Mac in safe mode (hold down the shift key while booting). Once in safe mode, go back to Internet Accounts in System Preferences and add your Yahoo! account. You should see your Yahoo! mail log in and start to fetch your mail. If it does, go ahead and restart your Mac, so it boots normally. This is what I did to get my Yahoo! to finally start working again.

Thanks for your response! Should I worry that it's taking a long time to load "mail" in system preferences? All the other services came up instantly. I do have a lot of mail, so if that is the issue I will be patient. Just wanted to make sure it wasn't stuck.

No, I would not worry. When I clicked on the Mail checkbox, it took a very long time for it to connect, but it eventually did. I think about 3-5 minutes. The other services, except Notes, enabled almost instantly.

If Mail fails to enable after the first try, keep trying.

I've got my inbox back now, and am sending and receiving messages. Thank you! However, I'm missing all my Yahoo! subfolders. The last time I deleted and reinstalled Yahoo! they came back, but not this time. Any ideas? The subfolders are still on the iPad and the web.

I think it's because Apple is not setting up the Yahoo mail account correctly under Yosemite. That's what I found for my yahoo account. Open the mail program and from the menus at the top select Mail/Preferences. Then select the Accounts tab and select your account for Yahoo. What does it say the incoming mail server is in the Account Information page?

I had to set my Yahoo account up manually because Apple was getting the information wrong for the incoming mail server and I could not change/correct the incoming mail server because it was not accessible when using the automated Yahoo mail set up.

Once I set it up manually typing in the correct information myself, the account rebuilt itself immediately including all my subfolders for my yahoo account.

If that's the case for you also, I posted what I had to do in my earlier post above.

I see now that when I reinstalled it put me back as POP, and not IMAP. Guess I'm deleting and reinstalling again. What a pain.

Any ideas how to get Yahoo! to install as an IMAP account? It keeps coming up as POP, and I don't see anywhere to change it.

I have been having this problem as well. The "inbox" folder is the only one not receiving new mail. Other folders (configured with a filter on Yahoo server-side) receive new mail. Just not "Inbox". I have deleted the account from Internet Accounts and re-added, no change. Clicked Synchronize, etc. Still no mail. This has happened on and off for the past several months. Running Yosemite, latest. Yahoo account added using all defaults. Everything works fine on iPhone, and using Thunderbird on same computer.

My issue is basically identical to what this guy posted:

http://apple.stackexchange.com/questions/167888/brand-new-10-10-yosemite-mail-ap p-can-not-work-with-yahoo-mail

I learned the trick is to use the "add other account" option and hold down the "option" key while clicking "next" after the credentials have been entered. This gives you the choice of IMAP or POP, and then you have to manually enter the incoming and outgoing mail servers. I don't know who to be more irritated with about this - Apple or Yahoo!/Pacbell

Thank You , Just try and work rigth away

Seems like there's a number of suggestions regarding this so I'll add mine since it was pretty simple for me. In one of the responses there's a link to the Yahoo Mail settings lookup: https://www.apple.com/support/mail-settings-lookup/

When I went to Mail=> Preferences=> Accounts=> Advanced, I noticed the Port Number shown was different than the Incoming Mail Server Port number that I received when I used the above link. I changed this value in the Advanced settings to the value provided from the link and I've been receiving mail ever since.

Good luck!

When I do this lookup, it only gives information for a POP account, and no option for IMAP.

I think the problem is yahoo acquired many email addresses. For instance my yahoo email address I've had for 15 years or so. It was originally Ameritech, then AT&T acquired Ameritech, which later became a yahoo address. Apple lookup shows my address server as inbound.att.net. That partially works but does not bring in all my folders I've created at yahoo. Plus it's not synced with my read/unread mail with Yahoo and there for my iOS devices registered with the yahoo server. So, manual setup seems to be the only way to point my email address to the correct yahoo mail servers. The problem is, Apple trying to be helpful, tries to automate all this and locks down the information so you can't correct it later. And setting it up manually is a little tricky because it seems they hide setting up everything manually. Plus there are some settings on by default which later lets apple manage your settings. And, they aren't getting the settings correct as can be seen in the lookup page.

See this article: http://guillaumeb.com/ym/imap.html

These settings below are apparently the default that Yahoo uses:

• Incoming Server - imap.mail.yahoo.com
• Outgoing Server - smtp.mail.yahoo.com
• Incoming Port - 993 (requires SSL)
• Outgoing Port - 465 (requires SSL/TLS)
• Username: full email address
• Password: the password you login to Yahoo! with.

Try to set up using these and see if it works.

Thanks,

John
