Condese File Error 80004005

Your file may be damaged. You may have 2 options:

1. Utilize the Condense Data utility to split the data. e.g you may create a new data file as of Jan 1, 2019

2. Purchase a 3rd party condense service.

Consider using a 3rd party service to condense your file.

Use a supercondense service to condense your data file. This service is available from a number of third-party providers.

Good morning, @JamesRaleighNC! I'm happy to see you reaching out to the Community for help on this issue. There's no need to delete any transactions in your account. Since you're using the Condense File option and receiving this error, I'd first recommend trying to rebuild the data. 

1. Go to the File menu, then hover over Utilities and select Rebuild Data.
2. On the QuickBooks Information window, select OK. Follow the onscreen steps to save a backup.
3. Let the tool repair your file. It may take some time but as long as you can move your mouse, the tool is working.
4. When the tool finishes, select OK.
5. Go to the File menu. Then hover over Utilities and select Verify Data.
6. Let the tool check your file for data issues.

If the tool finds anything wrong, click on Rebuild Now. Here's the full article with more information on this process: Fix data damage on your QuickBooks Desktop company file. After that, attempt to condense your company file again. 

The next option is to do a clean install. There are two ways of doing this and this article walks you through step by step: Clean install QuickBooks Desktop.
