Factors Triggering QuickBooks Multi User Error H505
• QuickBooks Multi-user error H505 commonly arises due to the failure to deactivate Multi-
User Access across all workstations, except the server. Neglecting to disable Host Multi-
User Access on these additional stations can create conflicts and jeopardize data 
integrity.
• Assigning exclusive hosting rights to the server computer is crucial for maintaining a 
stable multi-user environment. This practice guarantees seamless data access 
throughout the network, preventing potential complications and ensuring a smoother 
operational experience.
Resolving QuickBooks Error Code H505
Resolution of QuickBooks Error Code H505 involves diagnosing network settings to 
ensure seamless connectivity and addressing any disruptions in the server-client 
communication pathway. The most effective measures to apply include the following.
Solution 1: Modify QuickBooks Host Settings
This method ensures that only the server hosts multi-user mode, rectifying errors and 
improving QuickBooks accessibility throughout the network. To resolve QuickBooks error 
code H505 across affected workstations, follow these steps:
• Access QuickBooks and navigate to File.
• Under the File menu, choose ‘Utilities.’
• If ‘Host Multi-User Access’ is visible, proceed to the next workstation.
• If ‘Stop Hosting Multi-User Access’ appears, select it on each affected workstation.
• On the server managing the company files, open QuickBooks.
• Now head on to File and then select Utilities.
• If ‘Host Multi-User Access’ is available, select it; avoid opting for ‘Stop Hosting Multi-User 
Access.’
Solution 2: Utilize QuickBooks Database Server Manager
• To begin, access the QuickBooks Tools Hub and select ‘Network Issues.’
• Next, locate and open the ‘QuickBooks Database Server Manager’ on the server 
computer housing your company files.
• If it’s not installed, follow the prompts for installation. Inside the Manager, click ‘Start Scan’ 
to check for your company file folders; if not visible, manually locate and initiate the scan.
• The Manager automatically rectifies firewall permissions. Once the scan concludes, close 
the Manager.
• For any errors on workstations, open QuickBooks and navigate to File.
Now select ‘Switch to Multi-user Mode.’
• Ensure this process is conducted on the server computer, especially if it’s also used as 
a workstation.
