Question

outlook failure to communicate with yahoo server

Neena 0

Since the last update (Office 365), my outlook has become an exercise in frustration. Constant requests to provide passwords, won't update my yahoo accounts, get a 0x800CCC0E error code, have uninstalled and reinstalled Office 365 numerous times, yahoo unable to generate app password, Outlook appears to work but as soon as a shut down happens, it stops working and communication errors stop anything from updating.

I've booted/rebooted numerous times, I've uninstalled/reinstalled 365, I've deleted all outlook profiles and created new ones multiple times, I've checked with my ISP and they say it's a microsoft problem, I've shut off firewall but no help.

Everything on the yahoo email address works fine on the web and on my Apple phone. The problem is on both my desktop and laptop - identical issues. Desktop is Windows 11, Laptop is Windows 10. All softwares are the latest version.

Hi @Neena-4150 ,

Looks like your issue is a known issue and it is fixed, the Outlook Team added OAuth support for Yahoo IMAP accounts starting with build 16308.10000 in the Office Beta Channel and Current Channel (Preview). As of 8/2/23 Yahoo OAuth is now at 100% Current Channel. It's not at Monthly Enterprise Channel or Semi-Annual Channel yet.

If you are on channels such as Monthly Enterprise Channel or Semi-Annual Channel and you want to use Yahoo OAuth, you can switch to Current Channel using the guidance here, Change the Microsoft 365 Apps update channel for devices in your organization.

Honestly, I don't understand the response. I am a single user not an enterprise. I'm not an IT tech person. I need the response in simple, non technical language pointing me to exactly what I need to do to fix the issue.

Hi @Neena-4150 ,

What detailed version of Outlook are you using? (File > Office Account > About Outlook)

Version 2308 (build 16731.20078) is what it says on the subscription product screen. But when I click on “About Outlook” it says Microsoft 365 MSO (version 2308 build 16.0.16731.20052) 64-bit

Hi @Neena-4150 ,

Thanks for your reply.

According to the version information you provided, you are in Current Channel (Preview), Yahoo OAuth is now at 100% Current Channel. It is recommended you create a new profile and re-add your Yahoo account to Outlook Desktop, and you may see the Yahoo OAuth prompt.

If you see this prompt, make sure to use your regular password and not the app password.

And if you don't see the prompt, follow these steps to create an App Password in this article: https://support.microsoft.com/en-us/office/yahoo-oauth-password-guidance-3c96fc22-a31a-4382-8fa4-2ee9204b85a2

something is still not working. When I create a new profile, it asks me to connect an email address. The following sequence of screens is what I get. Note: I am NOT connecting to my Rogers email (it's a yahoo account white labeled as rogers), but keeps asking for my rogers email credentials. ROgers is also my ISP but those aren't the creds it's asking for. I've spent about 6 hours on the phone with Rogers and they maintain this is a Microsoft issue. Following is sequence of screens I get. Eventually, it does set up the email, but as soon as I close and then restart outlook, it starts asking me for Rogers credentials and I get a send/receive error - last screen shot.

Hi @Neena-4150 ,

Check that passwords saved in Microsoft Edge settings are correct (or in other browsers).

In addition, clear the cached credentials in the credential manager: https://support.microsoft.com/en-us/windows/accessing-credential-manager-1b5c916a-6a16-889f-8581-fc16e8165ac0

Hello everyone!

Many thanks to Brian Tillman for pointing out that Yahoo (also ATT.net email) requires the use of a secure mail key!! NOT YOUR EMAIL PASSWORD!!!

I worked hours trying to figure out connectivity issues with email on my new computer and eventually ran across Brian's advice:

AT&T requires an app password as well (they call it a "Secure Mail Key") because they use Yahoo for their mail service. See https://www.att.com/support/article/email-support/KM1240308/ This link points to a web site Microsoft doesn't own, but it appears to be safe, with no unwanted apps. However, it most likely uses cookies and may contain ads.

THANK YOU BRIAN!!
