Yahoo IMAP server - Rejected Password

My mail is working on my iphone although I have followed the instructions on it just incase... I've done it there but it's on my mac that I'm having problems... This is what I can see when I click on mail, contacts and calenders: http://tinypic.com/r/m7unwj/6

I haven't been following this too closely after I have stopped having issues and not sure if what I about to mention has already been tried or mentioned. I believe that after I removed the @yahoo.com from my user name under the account settings, I have almost never been asked for a password again. With that said, maybe once a week I will be asked for it. That could be just a timing issue or a load on yahoo's servers or maybe a security enhancement. Another thing I verified is that if I had logged in at the website, I do NOT have "Keep Me Logged In" checked.

I haven't been prompted for password for months now.

I also have fetch data enabled.

Mine seemed to rectify itself after my Ipad lost it's wireless connection and I had to re-enter all information.

Fingers Crossed!!

Ok I've managed to get it to recieve emails by going to my yahoo account online and enabling POP then when setting up my mail account changing it from IMAP to POP. Now I just can't send emails... So frustrating! At least I've done something though :/

You need to put your info into the SMTP field in settings.

CliCk on your account and then get the keyboard out of the way and click on the SMTP field and then in the next window click on the Primary Account. Now you will see the fields that need your information. Only on a POP do you need to fill in the info for SMTP.

Good luck

I tried everything to no avail. Decided to contact Apple. Talked to a really nice lady who told me to try logging into ATT mail directly from browser. Then while leaving the page up, open mail application. It worked. I'd actually erased the profile from mail app, so I did have to add it in again and this time, not a single problem!

The lady told me that they have no idea why this works! Hahaha. Whatever, I'll take it!

My situation:

Running Mac Mini with Mountain Lion.

2 Yahoo IMAP accounts, one of which works fine and the other of which started doing the password BS 4 days ago on my Mac Mail.

2 iOS devices, both of which are set up to receive Yahoo mail but neither of which had any problems accessing.

My solution (that has worked for the last 5 minutes or so):

Signed into Yahoo web account and changed password

Switched all iOS devices to "Manual" downloading of mail for the problem account

Started Mac Mail

Deleted Yahoo account in Mac Mail that was giving me problems

Created new account with new password

Voila, mail seems to be running fine again.

So I don't know whom to thank as I pretty much used a hodge-podge of solutions, but this thread was useful, so thank you all who posted your solutions in here.

It appears there is no solution that won't cost us $20. yahoo has formated their internet server to deny your pc/mac mail applications the right to access your emails "offline" with POP services unless of course you buy into their mail plus program or have a smart phone. So pay $20 dollars to view your email at your pc without opening it in your browser or just pull your phone out and do it for free. http://mailplus.mail.yahoo.com/

Been having this problem for ages with BTYAHOO IMAP servers. Yesterday I went into my keychain utility and deleted all paswords to do with BRYAHOO IMAP (there were quite a few) and voila it is now working fine!!

Everything syncs up just fine on my Samsung Galaxy Tab.

I'm seriously thinking about discontinuing using Yahoo because of this.

I haven't had this problem now for months and months ;o)

I did change settings on my Ipad and IPhone to fetch new data, but whatever has happened I am sorted!!!

Good Luck!

Have you tried my solution? Go into your keychain utility and delete all yahoo passwords. I had loads which were all the same. I was like you ready to quit yahoo after 15 years and now sorted no problems at all everything working and all syncing properly across mac ipfone and ipad.

I deleted all my keychains last week from two computers, and experienced the same problems and even more problems, so I restored the original keychain and just selected Keychain First Aid - Repair.

I've had the same problem with my yahoo accoutn getting locked out when I use IMAP on multiple devices. I cotnact yahoo support 4 times about this issue and finally they say they have found the fault on "their" servers. this is part of the response from them.

"We're pleased to inform you that we've completed our investigation and were able to identify a synchronization problem between your account and our server's database that could explain the sign-in error you were experiencing. The fix we've applied may take up to 24 hours to complete, but after that your Yahoo! account should work properly."

I don't know if this is the same issue for everyone but it seems they have fixed the issue. I will confirm this once I have re-enabled my account on all my devices that use IMAP.

Keep chasing Yahoo support they are trying to fix the issue it seems and I hope they have fixed it and in the next 24 hours I will know...
