Company files are stored on the server station only and only authorized users and admins can open the company file. In case your QuickBooks won’t open company file, this means your company file is either corrupt or you are not authorized to open the file from any workstation other than the server. To fix this issue, users are required to move the company file to another location. However, it is advised that any changes with the company file must be done in the presence of QB experts. So, to fix this issue, connect with the QB experts who are available around the clock to serve you and resolve your QB related queries.
