Resolution for Issue 'Can I unreconcile an entire reconciliation? I accidentally entered the wrong year and QB hasnot reconciled 15 months of transactions. I am late reconciling bank statements for 2016. Was working on Sept 2016 and accidentally entered it as 2017. The reconciliation was only off by $3 despite it being the wrong year. I used the auto adjustment and realized my error when I went to reconcile October 2016. Now all transations from 9-16 to 9017 are marked as reconciled and things are a hot mess. I do not see an option to undo the 9-17 recon in the Recon History page. How do I undo this without having and accountant and without having to manually undo 15 months of transactions manually?' available: Yes (Solved).
