How do I unmerge AT&T and Yahoo email accounts?
You may have been notified that your E-mail account is about to get unmerged. You may have had a merged account where your AT&T E-mail and Yahoo E-mail were merged into a single account, which allowed the password and inboxes to be shared.
If you are not sure if you have a merged account, it is likely you have one if:
- You can sign in to your merged E-mail account using either you AT&T or your Yahoo E-mail address.
- You can sign in to myA&T with either your AT&T or Yahoo E-mail addresses.
- You use the same password for both AT&T and Yahoo E-mail accounts.
- Your mailbox receives messages from both your AT&T and Yahoo E-mail address.
- When you reset the password, it changes the password on both Yahoo and AT&T accounts.
- When trying to reset your Yahoo password, it redirects you to myAT&T.
What is Happening?
Beginning mid-November 2017, you will no longer be able to sign in to myAT&T or att.net with your Yahoo ID.
Beginning early December 2017, all merged email accounts will be separated into two separate email accounts.
What does this mean to you?
Beginning in mid-November 2017, you will need to start using your AT&T email address to sign in to myAT&T instead of your Yahoo email address.
- To access your AT&T account in myAT&T, you’ll need to sign in using your AT&T email address. (Don’t worry, we’ll tell you what it is if you try to sign in with your Yahoo email address.)
- To access your AT&T email account through att.net, you’ll need to use your AT&T email address. (Again, we’ll tell you what it is if you try to sign in with your Yahoo email address.)
For a short time, you’ll still be able to sign in to your combined email account with your Yahoo email address on yahoo.com.
In early December 2017, you’ll need to start signing in to your AT&T and Yahoo email accounts separately since you will now have two unique accounts.
- The passwords will not change until you decide to change them.
- Your AT&T E-mail account will be empty. This includes E-mails, contacts, calendar, information associated with Yahoo sites (Yahoo Sports, Yahoo Groups, Tumblr, finance portfolios). All of this information will be on your Yahoo E-mail account.
- Your Yahoo E-mail password can be managed through the Yahoo Member Center.
What about my Sub-accounts?
- All Yahoo accounts will become stand alone accounts.
- Just like the parent accounts, any subaccounts that were linked to a yahoo account, the AT&T E-mail account will be empty and all the E-mails, contacts, and other things will be stay with the Yahoo account.
- The AT&T subaccounts will still be subaccounts under the primary AT&T E-mail account.
What about my E-mails, Contacts, and Folders
- Your E-mails, Contacts, and Folders for your merged accounts will be available when you login with your YahooID.
- For your Yahoo E-mail, Contacts, and Folder issues, please reach out to Yahoo.
- If you are getting an AT&T error message or not seeing your E-mails, Contacts, or Folders, such as a terminated account, try clearing your cache and cookies or using a different browser. Make sure you are logging in with your @yahoo.com account at mail.yahoo.com.
- You can reset your password at this site.
- If you are missing E-mails, you can recover your E-mail at this site.
Not able to Sign In
- Yahoo E-mail - Please contact Yahoo, as we no longer have access to Yahoo accounts.
- AT&T - Getting incorrect password? Go to our help article to get back into your account.
- Suspended / Inactive / Error 5188.8.131.52 - Accounts were disabled from inactivity during the unmerge. To fix this, try to sign in and after 48 hours, your E-mail account will become active again.
- Getting redirected to Yahoo site - Clear your cache and cookies or try using a different browser. Make sure you are logging into the right site. Go to att.net and click on the mail icon at the top-right.
