Error 21 on QB Desktop Pro

Hello Cruzking,

As support, our goal is to do what we can to help you get past errors slowing down your workflow so you can get back to your day-to-day tasks. I appreciate that you've shared the error you're seeing, the version of QuickBooks Desktop you're using, as well as your operating system. Those are great places to start, but to resolve these sorts of issues, we'll need more details, such as what you're doing when this error comes up, when it started happening, and what other details the error message might be giving you.

For that reason, I recommend calling in to our support team to get one-on-one help from an agent. While the community is great for getting answers to your questions, it's not built for in-depth error troubleshooting. Don't worry, a phone agent can get you back to business.

Take a look at the Intuit QuickBooks Desktop software support policies to learn more about getting in touch with support. Please note that due to staffing reductions in response to coronavirus, all Desktop support hours have been reduced to Monday to Friday between 9 a.m. and 8 p.m. ET.

Have a great weekend.
