How Can I Fix H505 When QuickBooks Can’t Connect To The Company File?

If QuickBooks can’t connect to the company file and shows H505, the issue usually involves the multi-user network connection between your workstation and the server. Check that the server is the only computer hosting the company file, while workstations have hosting turned off. You should also verify that QuickBooks Database Server Manager is running, the company file folder is properly shared, and your firewall allows QuickBooks to communicate across the network. Running QuickBooks File Doctor can also help identify network or company-file issues. If QuickBooks Error H505 continues, call +1(866)-513-4656 for assistance troubleshooting the connection and restoring multi-user access.
