One such error is QuickBooks Error H505, a multi-user mode issue that prevents QuickBooks from opening a company file. This error typically occurs when the company file is hosted on another computer, and you cannot access it on your own system. In this article, we’ll explore the causes of QuickBooks Error H505 and provide solutions to resolve it.

What is QuickBooks Error H505?

QuickBooks Error H505 occurs when one or more computers are unable to access the company file in multi-user mode. When this error appears, users cannot open the company file, and they may encounter messages like:

• "Error H505: QuickBooks is unable to open this company file."

• "This company file is located on another computer, and QuickBooks needs permission to access it."

This issue is commonly found in networked environments, where multiple users are accessing the same company file stored on a server or another computer.

Common Causes of QuickBooks Error H505

1. Incorrect Configuration of Multi-User Mode QuickBooks must be set up correctly to allow multiple users to access the same company file. Incorrect setup of QuickBooks in multi-user mode can trigger Error H505.

2. Firewall or Security Software Blocking QuickBooks A firewall or antivirus software may block QuickBooks from accessing the company file stored on another computer, causing the H505 error.

3. Misconfigured Hosting Settings QuickBooks relies on hosting services to allow multiple users to access the company file. If the hosting settings are misconfigured, it can lead to Error H505.

4. Damaged or Corrupt Company File If the company file is damaged or corrupt, it may fail to open, leading to the H505 error.

5. Network Connection Issues QuickBooks Error H505 can also occur if there are network connectivity issues between the systems trying to access the company file.

6. Improper Installation of QuickBooks Database Server Manager The QuickBooks Database Server Manager is a critical component for multi-user access. If this tool is not installed or configured properly, it can result in the H505 error.
