Thanks for reaching back to us and performing the steps shared above. I’m here to provide additional troubleshooting solutions to resolve Error code OL-222.

To start, I recommend updating the QuickBooks Desktop release version and making sure to create a backup copy of your company file and have the latest supported version of QuickBooks.

After that, let's correct again the unsupported characters in the .QBO file which causes this error:

1. Right-click the .QBO file and select Edit.
2. Select any text editor app to open the file.
3. Find and remove &amp from the text as it is an invalid character.
4. Save the file.

Once done, you can import the file once more to QuickBooks Desktop.

However, if the same error occurs, I recommend contacting our Support Team for further troubleshooting. To reach them, here's how:

1. Open QuickBooks. 
2. Go to the Help menu at the top.
3. Select QuickBooks Desktop Help. 
4. Type Contact Us in the search box. Then, click on Contact Us at the bottom. 
5. Select the way you wish to connect with support.
