If you are using a Yahoo, AOL, CompuServe, AT&T and other ISP accounts hosted by Yahoo and are having problems signing when you use Outlook desktop software, this is for you:
If you are unable to set up an Yahoo or AOL account in Outlook desktop, receiving an error that your username or password is wrong, you need to use an app password.
If the account is already configured in Outlook, you'll see this error message in the Send / Receive Progress dialog:
Task 'Synchronizing subscribed folders for ***@***.com.' reported error (0x800CCC0E) : 'Outlook cannot synchronize subscribed folders for ***@***.com. Error: Cannot connect to the server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'
You'll see this message when you add a new account:
Something went wrong
We couldn't log on to the incoming (IMAP) server. Please check your email address and password and try again.
Unlike Gmail, iCloud and Outlook.com, you do not need to enable 2-step authentication or the secret key feature to use an app password.
To generate an app password to use in place of your "real" password:
- Log into your account security settings in Yahoo or AOL and click on Manage app passwords.
- Type a name for your app then click Generate. (The name is to make it easier to delete (revoke) a specific password if you need to later. You can use the app password in any application.)
- Copy the password and paste it into Outlook’s password dialog. If you type it in, don’t include the spaces, they just make the password easier to read.
Use Ctrl+V to paste the password in the password field then click Next.
In older versions of Outlook, you can change the password in Account Settings. Go to File > Account Settings > Account Settings. Double click on the account and change the password.
I recommend copying and pasting the password into OneNote, Outlook Notes, or Notepad (or wherever you save things) so you have a copy if you need it with another mail client. The app password is valid until you revoke it.
