Hi @RdavidsonTHC Welcome to the Expensify Community!

I'm guessing you want to know what this error dialogue refers to? This looks to be an issue with your Quickbooks permissions.
To reset the permissions for your QuickBooks Desktop connection, first sign into QuickBooks as an Admin in single-user mode and go to Edit > Preferences > Integrated Applications > Company Preferences. From there, remove any instance of "Expensify Sync Manager" that you see listed. Save this change and click "Ok" to close the dialog box.
Next, try sync your policy again in Expensify. You'll be prompted to re-authorise the connection in QuickBooks.
Let me know if I can help with anything further!
