Recently, while using QuickBooks in multi-user mode, I got stuck with the QuickBooks Multi-user mode not working issue. It usually takes place when the user attempts to open the company file that is stored on another system on the server. On the occurrence of the error, I was not able to continue with the multi-user feature in QuickBooks and it puts the ongoing work at a halt. I visited different websites to find effective solutions to deal with the error, but I failed to fix the error. However, I came across a blog named QuickBooks Multi-User Mode Not Working, that helped me to resolve the problem.If you are still facing such an issue, then you can follow this article.
