How Do I Remove an Email Account from My Macbook Pro?

You could consider highlighting the Mailbox in question by going to the Toolbar, selecting “Mailbox,” then clicking on “Rebuild” from the drop-down menu. Continue to delete the mailbox – right-click or ctrl-click on it and select Delete from the menu when prompted.

Select Window > Previous Recipients in the Mail app on your Mac. Locate the address you wish to remove. You may search for it or sort the list by clicking a column header. Remove From List is the option to choose.

Select the Login Options tab, then deselect Allow Users to Log In Automatically. If you’ve previously enabled users to log in automatically, turn it off; otherwise, leave it on. Select your user or group from the drop-down menu below the list of users and then choose Delete (looks like a minus sign) from the drop-down menu beside it.

Remove all of your accounts. Then, when you visit Gmail, it will request that you login in and pick from your existing accounts. Below is a button to add an account or remove one. Remove the undesirable account by selecting the red (-) at the bottom of the page and then clicking Remove Account.

Make sure the user account you want to delete isn’t the only administrator account on the computer. If only one administrator account exists on the computer, you cannot remove it; instead, you must either convert one of the other accounts to an administrator status or establish a new adminisatration account and then delete the original.
