I was trying to connect another email account to my Comcast account and having problems - then I accidentally clicked "Ignore Warnings" and the account was set up. There's no way to delete it! How do I delete the account I know won't work so I can start over?
Are you referring to the "Add mail account" section in the left folders pane? If so, click on the gear icon in the upper right corner of the Inbox page, then on Settings>>>>>>>Accounts. To the right of the account in question you will see a trashcan icon. Click on that to delete the account.
