I am having the same trouble.  Would love to switch to QBO but we are a paperless office.  All of our financial records reside in Quickbooks Desktop.  If we switch to QBO, we will lose access to thousands of pdf attachments.  Intuit could solve this by selling some kind of legacy QBDesktop Viewer.  No entries could be made from it, but it would allow us to switch to QBO and still be able to look up our old records.  I need to view pdfs from old records several times a month.  If intuit could allow us to view the old file for a year or two, it would mean we had a way to use records without having to reattach years worth of attachments.  Intuit needs to keep in mind that if they really want QBO to be useful for companies currently on QBDesktop.
