QuickBooks Error H505: Switch to the
Multi-User Mode
When users try to switch to multi-user mode in QuickBooks, they frequently encounter QuickBooks
error H505. This can be very unpleasant for firms that require numerous people to access and work on
the company file concurrently. The error may point to several problems requiring immediate care for a
successful resolution.
When one or more workstations are set up to support many users, they substitute for the server PC and
produce the QuickBooks error number H505. This configuration is flawed because multi-user mode
should only be enabled on the server, which houses the company files. On every other workstation, the
hosting option needs to be turned off. If your company file cannot connect with the server, you may also
get the error H505 in a multi-user setting.

problem.
What Triggers Multi-User Mode Error H505 in QuickBooks?
Let’s get familiar with the issues why you are getting the error when switching to multi-user mode:
• The error H505 can occur when multiple workstations host the company file instead of just the server.
This improper hosting setup disrupts the correct functioning of multi-user mode.
• A firewall may block incoming or outgoing communication to the company file, preventing QuickBooks
multi user not working. This restriction prevents the necessary network connections for the network.
