How do I unreconcile a bank statement? Ideally I want to unreconcile the whole bank and start again.

Hello Sally28, 

Welcome to the Community page, 

To undo a reconcile, you need an account to do this as they are the only ones who can unreconcile a person's account so they can start again. So if you have an accountant you will need to speak to them, get them to log into their account, and find you as there client then they will go be able to unreconcile the reconcile you don't want and want to re do.
