A QuickBooks user canencounter
QuickBooksError H505 when he or she attempts to switch from single-user modeinto QB multi-user mode. The occurrence of this error means that QuickBooks in
multi-user mode is unable to connect to the server.
If
QuickBooks Error CodeH505 appears on the screen, it may be because one or more of the users’computers is set to be the QB server. The users’ computers can function in
multi-user mode, but only the server, i.e. computer hosting the company files,
should be the only machine configured to act as the host.
