I'm using Windows 8.1 Pro, and the Mail app has a Gmail account that "Needs Attention". I'd like to go ahead and remove it. I go to the Charms bar, Setting, Account, and find that Gmail account in the list of accounts, again with "Needs Attention" underneath it. I click on the account in the Settings->Accounts list, and a full screen banner asking for credentials pops up. If I dismiss this, the settings dialog closes. If I enter the credentials, a new Gmail account is added to the list, but the old one I want to remove is still there. Basically, there's no way to get past this credentials banner to the settings pane for the account, which is where the "Remove Account" button should be.
Does anyone know how to get around this?
Uninstalling the reinstalling the Mail app does not fix it. I know how to remove Windows 8 Mail app accounts normally, but it doesn't work in this case (it displays the credentials banner instead of the settings panel).
