Hello. My name is***** can help you with your question. This is an usually caused by malicious software but it can be caused by some buggy programming of the email providers logins.
What I would do is try doing the password ***** one more time and see if that allows you to proceed through the password ***** and set the password. Sometimes will take a minute or 2 for the new password ***** take effect. The one thing I don't know though is which provider you're having a problem with. If you can provide me with that information, I may be old give you information that's more specific to that provider.
