A QuickBooks user can encounter QuickBooks Error H505 when he or she attempts to switch from single-user mode into 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 Code H505 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.
