PROBLEM: "You may not create or edit a transaction dated on or before the dividing date."
SOLUTION: The dividing date is the date you gave a copy of your QuickBooks to your accountant.
No invoices or estimates dated earlier than the dividing date can be updated by All Orders, because your accountant is working on your invoices & estimates during this time period.
Once your accountant merges his changes back into your QuickBooks, then the sync will be able to update these invoices/estimates, and the error will go away.
