Like any software program, QuickBooks can sometimes display error codes and messages. Don’t panic! Most QuickBooks errors are easy to fix. Understanding the cause and solution will help you troubleshoot issues and get back to work quickly.

In this guide, we’ll cover the most common QuickBooks error codes and what they mean, so you can resolve any errors efficiently. Let’s get started!

H101: Unable to Connect

The error: H101 indicates QuickBooks is unable to connect to the company file hosted in the cloud. This often occurs due to internet connectivity issues.

The fix: Check your internet connection and try again. If the problem persists, restart your modem, router, and computer. Also, try connecting via a different network if possible. This will determine if the issue is with your local network or something wider.

H202: The Company File is in Use

The error H202 means the company file is already open elsewhere, so QuickBooks can’t access it. This prevents users from overwriting data accidentally.

The fix: Is someone else in the company still logged into the file? Ask them to log out. For QuickBooks Desktop, close the software on the other computer. Then reopen the file, and the error should clear.

H303: This Company File Cannot Be Accessed

The error H303 appears when QuickBooks doesn’t have access to open the company file. Permissions were denied, or the file was moved.

The fix: If hosting on your server, double-check that the file location entered in QuickBooks matches the actual location. Verify the QuickBooks DBMgr service is running and has proper permissions. You may need your IT support to assist.

-6000, -82

The error: Error codes -6000 and -82 indicate issues creating a new company file or opening an existing file. This is very common if you are using QuickBooks for the first time.

The fix: Review that the file path and name are spelled correctly when setting up a new file. If the file exists, try copying it to your desktop and opening it from there. Also, try rebooting and reinstalling QuickBooks. This often resolves new file errors.

-6123, 0

The error -6123, 0 occurs when company files have become damaged and unreadable by QuickBooks. This can be caused by a sudden software crash or a power loss.

The fix: Run the Verify Data utility in QuickBooks to check for and repair any corrupted data. If that fails, a hands-on data recovery service may be required to rebuild transactions into a new company file.

-6190, -8290

The error: These errors indicate the QuickBooks Database Server Manager is not running properly. This service allows multi-user access to company files.

The fix: Use the Task Manager to end any QuickBooks processes or services still running in the background. Then restart the QuickBooks DBMgr service. This should clear errors -6190 and -8290.

10, 16, 3

The error: Error codes 10 and 16 relate to logging into QuickBooks. 10 means multiple login attempts failed. 16 indicates a login and password do not match.

The fix: Carefully re-enter your credentials to connect again. If needed, use the “I forgot my password” link to reset. For error 10, you may need your admin to create a new user profile if your login continues to fail.

OLSU-1024

The error OLSU-1024 pops up when installing a new version of QuickBooks, and your license has expired.

The fix: Locate your license and registration number in your original welcome email from Intuit. Re-enter this information during the installation. Or contact customer service, and they can reset your license remotely. This will clear the OLSU-1024 error.

Correcting QuickBooks errors is typically straightforward once you know the cause. With this overview of common codes, you can get back to work with minimal disruption.
