Oh No! QuickBooks Error 80040408 – What To Do?

Listen to this article

QuickBooks Error 80040408 is an unexpected bug result due to incorrect settings and configuration of QuickBooks in a multi-user environment. Mostly, this arises from network problems, security software conflicts, outdated software versions, or corrupted QBWebConnector.

Begin Session Failed. S0000 00000 [QODBC] QB Begin Session Failed. Error = 80040408. Could not start QuickBooks” 

or

“QBXMLSession_OpenConnection File named F:\QB Data\Rock Castle.QBW is not opened.

BeginSessionError Code: 80040408 Could not start QuickBooks.”

The error code 80040408 occurs while using the QB application in the multi-user environment and does not let you access the company file. There might be multiple reasons behind this error, which are discussed in the further sections of this guide, so keep following it till the end.

10 Reasons Behind QuickBooks Company File Error 80040408

The QB Begin Session Failed Error = 80040408 comes directly from the Intuit Software Development Kit (SDK). It basically indicates that QB is unable to open the requested company file because it is not clear to do so. There can be multiple reasons behind this, which are as follows:

  1. Someone else has currently opened QuickBooks in single-user mode.
  2. The QB company file that you are trying to access is running on a different workstation in single-user mode.
  3. QuickBooks is opened by another user using the same QuickBooks QQube user that you set up to connect to QB.
  4. The company file name has been changed, and it no longer matches the name that was initially used when it was added to the QQube Configuration Tool.
  5. Somebody has moved the QuickBooks company file, and it is now in a different location than what was initially set up inside the QQube Configuration Tool.
  6. QuickBooks Desktop is running as an administrator. The QQube can not communicate with QB if it runs as an administrator, and thus, you get error code 80040408.
  7. QuickBooks is set to open a particular company file before trying to open multiple files. 
  8. In multi-user mode, the dedicated server responsible for responding to your request is logged out/shut down, and thus, QuickBooks cannot run.
  9. The QuickStart option is enabled and running on the system.
  10. More than one QQube synchronizer is running on the server or workstation. On the workstation, only the user for whom you have installed QQube should be the synchronizer. In a multi-user server environment, there should only be one dedicated synch user. If these requirements are not met, you may face QuickBooks error 80040408.

7 Troubleshooting Solutions For QuickBooks Error 80040408

There are different troubleshooting methods to resolve the QB error 80040408. The simple methods to resolve it include undoing the changes made to the company file name or path, disabling the Quickstart feature, configuring the QQube tool, etc. So, let’s look at these solutions in detail:

Solution 1: Rename the QuickBooks Company File Back to the Original

Changing the company file name can make it inaccessible and lead to Intuit QB Error Code 80040408. You can simply fix it by renaming the file back to its original name. You cannot change the company file name in the QQube Configuration Tool Directly; you need to change it to the original name through the server. Here is how you can rename the company file in QuickBooks:

  • First, back up the QB company file.
  • Then, check the location of the company file from the Home page.
  •  Press the F2 or Ctrl+1 keys to open the Product Information window and note down the location from the File Information field.
  • Right-click the Windows Start button, select File Explorer, and then go to the specified location.
  • After this, right-click the company file and hit Rename. The name of the file may appear as [CompanyName].qbw or just [CompanyName].
  • Then, change the file name and hit Enter.
  • Lastly, hit Yes to confirm the action.

You also need to set up the QB Desktop application to use the new company file name.

  • For this, from the File menu, click Open or Restore an existing company.
  • Then, choose Open a company file and then Next.
  • After this, click Open after selecting the newly renamed company file.

Open the renamed company file on all the workstations that you use in the multi-user environment.

Solution 2: Restore the Company File to the Original Path

If you have recently moved your file and changed its path, you must change the company file path back to what it originally was. You can use the QQube Configuration Tool to do so. However, if you use the multi-user mode, then you need to do this on the server while logging in as a dedicated user.  You can also check the simple instructions to restore QuickBooks Backup file to avoid any data damage.
