When users choose to create a case from an email it does not auto populate the account name in the case form. It works fine if you view a customer and create a case from the detailview page but not from an email (Yes the customer does exist with the same email address)

Also when I view a customers details it's not showing the emails in the history, so it's obviously not linking the email with the account, any thoughts on what may be the cause of this?

Thanks in advance,
Sean
