QB Issue Resolution:
The Undo Reconciliation option is a feature that is only available in the Desktop version of QuickBooks. While it is possible to manually unreconcile we do not recommend it. To manually unreconcile entails a tremendous amount of time and work and does not always solve the root cause of the problem you are experiencing.
We have created a KnowledgeBase article to assist you in troubleshooting reconciliation problems. There are three general categories that all reconciliation problems fall within. Troubleshooting for each of these situations takes a fraction of the time that a complete un reconciliation and re-reconcile would entail. The following KnowledgeBase article covers all three scenarios, http://oe.quickbooks.com/support/answers.cfm?faq_id=2910.
I hope this helps:)
