Invoice reminder will not populate with my customer list in QuickBooks Desktop

I can help you resolve the error you're having with your invoice reminder, @Copes1.

There may be some minor data issues with your company file that's why you're having trouble with your invoice reminders. Try running the Rebuild and Verify Utility tool to fix possible data damage on your company file.

Please follow the steps below:

1. Open your company file again.
2. Go to the File menu, then select Utilities and choose Rebuild Data.
3. Click OK in the QuickBooks Information window.
4. Wait until the repair is done. Then, click OK.
5. Then, go back to the File menu and select Utilities and choose Verify Data.
6. Click OK if QuickBooks doesn't find any problems. Or Rebuild Now if it finds issues with your company file.

If you still get the same issue, let's try running the QuickBooks File Doctor to fix common issues. 

1. Open your QuickBooks Tool Hub.
2. Select Company File Issues.
3. Click Quick Fix my File.
4. Choose OK when it completes and launch your QuickBooks.

Thank you so much for the response. I ran through ALL your suggestions and still have nothing populating.  I even deleted my groups and schedules just to start over...again. I don't get any issues now with Rebuild or Verify.

When I look at the customer email list after parameters, it shows 30. I set everything to do reminder at 1 day after due date (just for ease in finding the issue here). My company preferences is also set to one day. We are currently 5 days late so it should pull up the 30 to email reminders. Once I go to Customers:Reminders: Review & Send reminders...the screen comes back empty.

At one point I played with the Statement options too and edited as above. Customer list still pulled the 30, but the email screen only listed 5 customers. 

I don't understand what is holding this back or what is off? I've been working on this off and on for months now. Each time I start over when it fails and reread all steps to begin again. I can't possibly be getting it wrong every time?!?!?! 

Thanks for going through the troubleshooting steps above and for sharing an update with us, @Copes1.
