QuickBooks Error 6073-99001: Complete Error Fix Guide

QuickBooks Desktop is widely used by businesses to manage accounting, invoicing, payroll, expenses, and financial records. When multiple users work with the same company file, QuickBooks depends on proper network access, hosting settings, folder permissions, and multi-user configuration. If one of these components prevents the application from accessing the company file correctly, you may encounter QuickBooks Error 6073-99001.

This error commonly appears when you attempt to open a company file and QuickBooks determines that the file may already be open by another user or cannot be accessed correctly through the network. Intuit describes error -6073, -99001 as an issue that can occur when the company file is open elsewhere in Single-User mode, stored in a read-only network folder, accessed through certain Linux-server configurations, or affected by remote-access software.

Fortunately, the problem can often be resolved by checking the company file's hosting status, network folder permissions, and QuickBooks configuration.

What Is QuickBooks Error 6073-99001?

QuickBooks Error 6073-99001 is primarily associated with company-file access problems. It can prevent a user from opening a QuickBooks Desktop company file, particularly in a multi-user environment.

A typical message may state:

“QuickBooks is unable to open this company file. It may have been opened by another user.”

The error codes displayed are:

(-6073, -99001)

The message can be confusing because the company file may not actually be open by another person. QuickBooks may instead be detecting a hosting conflict, an incorrect file permission, an interrupted remote session, or another configuration issue that prevents normal access.

Why Does QuickBooks Error 6073-99001 Occur?

Understanding the possible cause is important before changing settings. Some of the most common reasons include:

1. Company File Is Open in Single-User Mode

One of the most common causes is that another workstation has already opened the company file in Single-User mode.

QuickBooks allows multiple users to access a company file when multi-user mode is configured correctly. If another workstation has exclusive access to the file, another user may be prevented from opening it.

2. Network Folder Is Read-Only

QuickBooks needs appropriate read and write permissions to access a company file stored on a network.

If the folder or user account has insufficient permissions, QuickBooks may be unable to establish the required connection.

3. Incorrect Hosting Configuration

Hosting should be configured correctly for the computer or server responsible for providing multi-user access.

If hosting is incorrectly enabled on a workstation, it can interfere with the way other computers connect to the company file.

4. Remote Access Software Is Still Connected

Remote-access applications can sometimes leave a session active after a user disconnects.

Intuit specifically identifies remote software such as LogMeIn and GoToMyPC as a possible factor in this error when the host computer still considers the remote user logged in.

5. Linux Server Authentication Configuration

Intuit also notes that the error can occur when QuickBooks company files are hosted on a Linux server and more than one set of login credentials is being used to access the shared folder.

6. Network or Company-File Problems

A damaged company file, incorrect network configuration, or problem communicating with the host computer can also contribute to company-file access failures.

How to Fix QuickBooks Error 6073-99001

Try the following solutions in order. After completing each solution, attempt to open the company file again.

Solution 1: Close QuickBooks on All Computers

Start with the simplest troubleshooting step.

1. Ask all QuickBooks users to save their work.

2. Close QuickBooks Desktop on every workstation.

3. Make sure no user is still connected to the company file.

4. Check the host computer as well.

5. Restart the affected workstation if necessary.

6. Open QuickBooks again.

7. Try opening the company file.

If another computer had the company file open in Single-User mode, closing QuickBooks on all workstations may release the file and restore access.

Solution 2: Switch to Multi-User Mode on the Host Computer

If the company file is supposed to be used by multiple people, check its mode on the host computer.

1. Open QuickBooks Desktop on the computer hosting the company file.

2. Open the company file.

3. Select File.

4. Look for the option related to switching to Multi-User mode.

5. Select Switch to Multi-User Mode if the file is currently in Single-User mode.

6. Allow QuickBooks to complete the change.

7. Try opening the company file from another workstation.

Intuit recommends switching the company file to Multi-User mode when it has been opened in Single-User mode on the host computer.

Solution 3: Close and Reopen the Company File

If QuickBooks is already showing Multi-User mode but the error continues, close the company file on the host computer.

1. Open QuickBooks.

2. Select File.

3. Choose Close Company.

4. Wait for QuickBooks to close the file.

5. Select File again.

6. Choose Open or Restore Company.

7. Select Open a company file.

8. Select Next.

9. Browse to your company file.

10. Choose the option to open the file in Multi-User mode.

Afterward, test the file from another workstation.

Solution 4: Check Network Folder Permissions

If your company file is stored on a network folder, verify that the affected user has appropriate permissions.

On the computer hosting the company file:

1. Locate the folder containing the company file.

2. Right-click the folder.

3. Select Properties.

4. Open the Security tab.

5. Select the Windows user experiencing the problem.

6. Review the assigned permissions.

7. Make sure the user has the necessary access, including permission to modify the files.

8. Apply the changes.

9. Restart QuickBooks.

10. Try opening the company file again.

Intuit specifically recommends checking folder permissions when the company file is located in a read-only network folder.

Important: Avoid changing permissions unnecessarily for unrelated folders. Make changes only to the folder used for the QuickBooks company file.

Solution 5: Run QuickBooks File Doctor

QuickBooks Tool Hub includes utilities that can help diagnose company-file and network-related problems.

One recommended approach is to use QuickBooks File Doctor.

General steps include:

1. Close QuickBooks Desktop.

2. Open the QuickBooks Tool Hub.

3. Go to Company File Issues.

4. Select Run QuickBooks File Doctor.

5. Choose the affected company file.

6. Enter your QuickBooks administrator credentials when prompted.

7. Allow the tool to examine the company file and network configuration.

8. Wait for the process to finish.

9. Open QuickBooks again.

10. Test the company file.

Intuit's guidance recommends QuickBooks File Doctor as an initial troubleshooting option for this error.

Solution 6: Use Quick Fix My Program

If the problem appears to involve the QuickBooks application or a remote-access session, Quick Fix My Program may help.

1. Close QuickBooks Desktop.

2. Open QuickBooks Tool Hub.

3. Select Program Problems.

4. Choose Quick Fix My Program.

5. Allow the utility to complete.

6. Restart the computer if prompted.

7. Open QuickBooks Desktop.

8. Try accessing your company file.

Intuit specifically recommends Quick Fix My Program for certain remote-access situations involving this error.

Solution 7: Check Remote Access Sessions

If your business uses remote-access software, check whether another session is still active.

For example, an employee may have disconnected from a remote computer without properly closing QuickBooks.

Ask users to:

• Sign out of remote sessions.

• Close QuickBooks properly.

• Disconnect unused remote connections.

• Restart the host computer if a stale session remains.

• Reopen QuickBooks and test the company file.

This can be especially useful when the error suddenly appears after a remote user disconnects.

Solution 8: Check Hosting Settings

Hosting configuration should be consistent with the way your QuickBooks environment is designed.

On workstations:

1. Open QuickBooks Desktop.

2. Select File.

3. Choose Utilities.

4. Review the hosting-related options.

5. If the workstation is not supposed to host the company file, make sure hosting is not enabled there.

On the designated host computer, verify that the appropriate hosting configuration is being used.

Avoid enabling hosting randomly on multiple computers because doing so can create additional multi-user access problems.

Solution 9: Restart the Host and Workstations

Sometimes an old QuickBooks process or network connection remains active even after the program appears to be closed.

A controlled restart can help refresh:

• QuickBooks processes

• Windows network connections

• Database services

• Remote sessions

• File locks

First close QuickBooks on all computers. Then restart the host computer and affected workstations. Once the systems are back online, open the company file from the host and test multi-user access.

What If QuickBooks Error 6073-99001 Still Appears?

If the error continues after the basic troubleshooting steps, avoid repeatedly opening and closing the company file without determining the underlying cause.

Check the following:

Verify the Company File Location

Confirm that the .QBW company file is located in the intended folder and that users are connecting to the correct network location.

Check the Network Connection

Make sure affected workstations can communicate with the host computer. A temporary network problem can prevent QuickBooks from accessing the company file.

Review Folder Permissions

Confirm that the Windows account being used by the affected employee has appropriate access to the company-file folder.

Check Multi-User Configuration

Review the hosting configuration and make sure the designated host is correctly configured.

Look for Active Users

Ask all employees who work with the company file whether they still have QuickBooks open. Also check remote connections that may have remained active.

Protect Your Company File

Before performing advanced troubleshooting, maintain a reliable backup of your company data. Avoid deleting or modifying QuickBooks data files unless you understand their purpose and have a verified backup.

How to Prevent QuickBooks Error 6073-99001

Preventing access conflicts can reduce interruptions in a multi-user QuickBooks environment.

Maintain Correct Folder Permissions

Review network folder permissions periodically, especially after changing employees, computers, or Windows accounts.

Keep QuickBooks and Windows Maintained

Regular software and operating-system maintenance can help reduce compatibility and network-related problems.
