I have successfully used Outlook 2011 with my personal Gmail account for some time.

Recently I tried to add a second Gmail account for my work email address and keep getting an error message:

"The server for account "xxxx" returned the error "Invalid credentials j20mb4919854wiv." Your username/password or security settings may be incorrect. Would you like to try re-entering your password?"

I have:

1. Enabled IMAPaccess within the Gmail account settings

2. Followed Google's instructions for setting up a new IMAP account

3. Checked whether there are any differences between the setting on my personal account, and the new work account which would explain the problem.

Any ideas about what is going wrong?
