Hi there, @LaurieJL.

I appreciate you following the steps shared by my colleague above to reactivate accounts. Let's run the Verify and Rebuild Utility Tool to check the integrity of your data on your company file. This way, way we can fix your issue with reactivating accounts.

Here's how:

1. Go to the File menu, then select Utilities.
2. Choose Rebuild Data and click OK.
3. Wait until the tool repairs your file. Select OK once finished.
4. Go to the File menu, then select Utilities and choose Verify Data.
5. Let the tool check your file for data issues.

Once done, try to reactivate an account again to double-check.

If you get the same result, let's repair your company file using QuickBooks File Doctor. For more guidance, feel free to check out this article: Fix company file and network issues with QuickBooks File Doctor.

If the issue persists, please read this article for more troubleshooting steps: Fix data damage on your QuickBooks Desktop company file.

Please let me know if you need clarification about this, or there's anything else I can do for you. I'll be standing by for your response. Have a great day.
