How to un-reconcile an account?

[Mark Phillips]

How do I un-reconcile an account?

I deleted some reconciled transactions by mistake, so I want to
un-reconcile the entire account and go back to before the transactions were
deleted and reconcile the account again. I opened the account in June, and
I don't mind going back to the very beginning and reconciling the account
again from June1.

Thanks!
