Having issues with being able to integrate your Yahoo mail on your BlackBerry? You're not alone. The issue has arisen for plenty of folks in the CrackBerry Forums recently due to some changes made at Yahoo.

Unfortunately, there is a multitude of reasons an email address can't be added. Fortunately, though, a new BlackBerry Knowledge Base article takes them all into account so that you can handle the issue with whatever one best relates to your situation.

Overview

Attempting to add a Yahoo! Mail account on a BlackBerry smartphone running BlackBerry 7 and earlier, the following error message is displayed:

  • Invalid email address or password. Verify your email address and password. If the error persists, contact yahoo.com

Attempting to add a Yahoo! Mail account on a BlackBerry PlayBook, BlackBerry 10 smartphone or BlackBerry Hub for Android, one of the following error messages is displayed:

  • Unable to find connection information. Please use Advanced setup.
  • Your login information for account (user@yahoo.com) has changed or is incorrect. Update your login information and try again.
  • Your account can't be authenticated. Update your account settings and try again

Cause

  • Cause 1 - On BlackBerry OS and BlackBerry 10 devices the authentication for Yahoo and Rogers accounts have changed.
  • Cause 2 - The login information entered for the Yahoo! Mail account is incorrect.
  • Cause 3 - Yahoo! is disallowing access to app's they believe are less secure. Full explanation for this can be found at the following link: https://help.yahoo.com/kb/SLN27791.html
  • Cause 4 - The Yahoo! Mail account is inactive. This can happen if the account was not accessed for a period of four months.
  • Cause 5 - The Yahoo! Mail account is expecting a CAPTCHA response.
  • Cause 6 - The Yahoo! account authentication token has expired.
  • Cause 7 - The Yahoo! profile indicates that the user is 13 years of age or younger.
  • Cause 8 - Second sign-in verification is enabled on the Yahoo account.
  • Cause 9 - Yahoo! is moving towards a "Password Free" service and the authentication has to be done via a verification code.

Resolution

  • Yahoo.ca
  • Ymail.com
  • Rogers.com
  • ATT.net
  • btinternet.com
  • SBCGlobal.net
  • Verizon.net

Hopefully, that will help some folks out. Though, maybe, you'll want to take this time to consider switching providers. Every day, folks in the forums seek help with their devices and out of all the email providers out there, Yahoo is consistently the one folks have the most trouble with whether it be setting up the account or the service just being down or otherwise unavailable in general.
