Transfer ALL emails from Your OLD Gmail Account to New Gmail Account HD

Error: Server denied POP3 access for the given username and password. This was posted by a viewer.Thanks +an8er !! Solution: Log into your old Gmail account, run these links into browser: https://accounts.google.com/DisplayUnlockCaptcha (click "continue") https://www.google.com/settings/security/lesssecureapps (select "turn on") Wait a few minutes for an eMail saying "Access for less secure apps has been turned on". Only THEN can you continue. Log out, go to your new Gmail account and add the old Gmail account. This video shows you how to transfer your emails from one GMail account to another GMail account. *This does not mean your email address has to be @gmail.com. It also works for schools that use Google Apps for Education and provide employees and students with email service through GMail. It may work for other types of accounts, but I have only tried GMail to GMail
