If you retrieve your email via POP from Gmail, you may on occasion find that Gmail completely rejects your password. Now, having Gmail rejecting your POP password can be very disconcerting, not to mention frustrating! Your mail client keeps prompting you for your Gmail password, you keep entering the password that you know is the right password, and Gmail keeps rejecting it.
It’s enough to drive you crazy.
But don’t let it, because you’re not crazy, and it’s not you – it’s Gmail. And you can prove it to yourself by logging in to your Gmail account via the web, using the same password that you know is your correct password – the very same password that Gmail keeps rejecting in your efforts to POP your mail.
Nobody seems to know why this happens. And, unfortunately, nobody seems to know how to fix it, other than to just wait.
Some people have said that they have had success closing down their mail program, and re-opening it. Others have said that rebooting their machine has helped. These things are worth trying but if they don’t work, just know that this too shall pass, and all you can do is wait it out.
