Attachments-converting from QB Online to Enterprise desktop

Good evening, @tiska4mo. 

Welcome back to the Community! 

You'll need to re-attach them manually. To retain these attachments, you need to manually download them from QuickBooks Online and then re-upload them to the corresponding transactions in QuickBooks Desktop. 

If you have large volumes of attachments with certain transactions, we recommend looking into a third-party app. Exploring third-party applications specifically designed to help with bulk uploads of receipts and other documents in QBDT. 

In addition, submit feedback to our Product Developers so that they can consider adding some more features when migrating data to other versions of QuickBooks. 

If you have any further concerns, please let me know. I'm only a post away if you need me!
