Quickbooks Enterprise Nonprofit v23 Attach feature not working

Thanks for reaching out to the Community, Nadeen1192. I appreciate your detailed information.

Since you've already used the Verify and Rebuild Data utilities, but your Attach option isn't working properly, I'd recommend troubleshooting with our QuickBooks Tool Hub.

Here's how:

1. Close QuickBooks and download a copy of the utility's most recent version, then run it.
2. Follow along with your on-screen steps to complete installation and agree with our terms and conditions.
3. Once it's installed, double-click its icon to open the tool hub. If you can't find your app, perform a search in Windows for "QuickBooks Tool Hub" and select the program.
4. Access your Company File Issues tab and use the Quick Fix my file and QuickBooks File Doctor tools to troubleshoot your company file. In the event you need additional assistance, choose File Dr Help.

If your Attach option continues to not function properly, you'll want to get in touch with our Customer Care team.

Here's how:

1. In your top menu bar, go to Help, then QuickBooks Desktop Help.
   
   
    
2. Click Contact Us.
   
   
    
3. Enter a brief description of the issue in our Ask a question (or tell us what's wrong) field, then hit Continue.
   
   
    
4. Select We’ll contact you for a callback or Message Us to start an instant messaging session.

Be sure to review their support hours so you'll know when agents are available.

If there's any additional questions, I'm just a post away. Have a lovely Tuesday!
