Since updating to 8.1, my Yahoo! Mail no longer synchronizes updates. No settings have been changed, and all login credentials are correct and were working as normal prior to 8.1.

[dfaris]

I'm having the same issue and I did not update to 8.1 yet.

[Ixia]

Mine's working fine since the update, which makes a change as it is prone to issues.

[Madam ImAdam]

I trying to see if it has something to do with being part of a Linked a Inbox. On my iPad, my Yahoo! Mail account is working normally, so it us not a Yahoo server issue.

[dfaris]

Yahoo always has issues especially with phones.

What happens when you delete the account and add it again?

[Madam ImAdam]

I just unlinked the inboxes, no effect, then deleted and re-added the account. Under settings, email+accounts, it is grayed-out and "synching..." for about the last half-hour.

[dfaris]

Let us know if that works.

Mine has been working smoothly since installing the update on Monday (knock on wood). It has acted up periodically since I got the phone, though, so who knows if it will keep working? Screws up on my PCs pretty regularly, too, usually reporting that my credentials are wrong when they're not.

[dfaris]

Mine is still not working and I'm on WP 8 since 8.1 is not out for the 1020 on ATT yet. I'm guessing it is not a 8.1 issue.

[Torcher Death]

Mine's not working properly either ... L520 on WP8.0 here
Inbox is fine, but not able to send any mails...starts popping up that credentials are invalid message, until I remove & re-syn.

[dfaris]

I'm at 19 hours now with not sync. I tried deleting the account and redoing it but that did not work.

[aikidaves]

Do you have another device you can use to access your account to see if it's only your phone or if it's an account problem?

[dfaris]

Works fine on my desktop and windows tablet so far it is just my phone.

[dfaris]

Its been over 24 hours now. Anyone else have any luck getting yahoo to work?

[akthelonelyman]

happens to me a lot these days. don't know why.especially on wifi. i sync it manually time time to check for new emails. though when on cellular data is almost works as usual.
the email app has gone kinda unreliable in cyan update.

[dfaris]

Going on two days now. Can't get yahoo to sync on WiFi or cellular.

[dfaris]

Well for anyone still having issues. I deleted my email account again and added it back in use the settings below and it seemed to work
for now.
Yahoo email
Incoming Mail (IMAP) Server - Requires SSL
Server: imap.mail.yahoo.com
Port: 993
Requires SSL: Yes

Outgoing Mail (SMTP) Server - Requires SSL

[Madam ImAdam]

Nothing has resolved this for me. Yahoo mail tajes hours to synchronize on the a Windows Phine, and is working instantaneously on my iPad. It's becoming very frustrating.

[dfaris]

Well I'm just got 8.1 for my phone and yahoo seems to be working just fine.

[DJWhiteSquall]

I'm getting the same scenario on my 1020, but not with Yahoo, its happening to my Outlook email. Mine hasn't synced since 8am today, and this has started to happen quite frequently.

The error message I end up getting (80C805E2) says "last updated about a week ago." its being kind of hard on itself because it was clearly downloading email this morning at 7.

[Ixia]

Arghh...It's playing up again, now it keeps saying my password is incorrect (it isn't) and it won't sync, so I can't get my email at all. Really sick of this, wish I knew if it was a wp8.1 issue or a Yahoo issue. I suspect it's WP, as I have no issues using my yahoo account on the PC.

[aikidaves]

I'm actually pretty sure it's a Yahoo issue, as I've been having this off and on for years on my PC. It hasn't happened at all since I got my Lumia in April. Go figure.

[Andrew Gordon]

I've been having problems with Yahoo and Ovi accounts on and off for months but today my Ovi account just flat out refuses to sync or accept my password on either my 1520 or on Windows 8.1.
I've changed passwords and deleted both accounts but it still isn't working. Accessing my account through a browser works fine though.
I've given up trying to fix it now and just hope that whatever is causing the problem is resolved soon.

[gwcams]

It's happening on both my PC and WP. I have even tried adding it as a Yahoo account
