We need help properly configuring Quickbooks, MS Access VBA and QODBC to work in multi-user mode. Specifically, we have 8-10 companies that we need to aggregate data across. We have successfully connected to and pulled data from multiple companies in single-user mode using VBA within Microsoft Access along with QODBC. However, our production QB files all need to remain in multi-user mode. When we go through the exact same steps to get everything set up in multi-user mode, we are able to connect to the QB company files, but no data is returned, and (perhaps unrelated) the QB company file is somehow being changed back to single-user mode.
