There are times when you are unable to access your Google account even after resetting the account password. When this happens there are two steps that will almost always resolve the problem.

The first step is to clear your browsers cache and delete your cookies. If you are unsure about how to delete your browser cookies or clear it's cache please see your browsers help section. Another helpful resource can be found here. I would suggest restarting your browser after deleting your cookies.

If deleting your cookies and clearing your cache does not solve the problem your account may be "locked". To "unlock" your account do the following. (This step is required if your desktop client is having problems logging in.)

1. Disable all mail clients you're using to read mail. (If you use one at work and one at home, please disable both.)
2. From the computer on which your logins are failing, visit https://www.google.com/a/[yourdomain.org]/UnlockCaptcha.
3. Enter your email username and password, and the letters in the distorted picture.
4. Once you have successfully logged in, restart your mail client and try to download your mail.
