Quickbooks error code H505 can occur when running the program in a multi-user environment. Setting up multi-user mode in QuickBooks enables multiple users to access the company file simultaneously. The company file is hosted on the server computer, and the workstations access the data file stored on it.
However, if the hosting is not properly done, you may get this error. In error code H505, you will get an error message on your screen, which states that the file you are trying to access is located on another computer. Check if your network is intact and Firewall is not preventing QuickBooks from communicating with the server. For additional help, you can get in touch with our QuickBooks experts.
