You're presumably signed into a TalkTalk mailbox. I'll call that the primary mailbox.
The error message is presumably about an added email account. I'll call that the secondary mailbox.
- Select the Main Settings Menu
- Select the Settings menu item
- Select Accounts from the left side panel
- Select Edit for the secondary mailbox that needs the correct credentials
- An editing window will appear
- Scroll down to the Password box, select inside the box and backspace
- Enter the correct current password for the secondary mailbox
- Select Save
If you wish to remove the secondary mailbox from the primary mailbox just select the dustbin icon to the right of the secondary mailbox and then confirm Delete account. This action just removes the secondary mailbox from the primary mailbox but does not delete the account.
However, the email address you posted, is showing as not valid on the system. If you've deleted it from your MyAccount then just follow the above advice to remove this secondary mailbox from the primary mailbox.
If you haven't deleted the secondary mailbox from your MyAccount then let us know what error message you see when trying to sign in directly to the secondary mailbox.
Let us know how you get on.
