Hi Wesley, Welcome to Laserfiche!

The Everyone account should be a Laserfiche built in account, and not a Windows account.  It has a role in initial system set up, and in providing access to volumes over the long run.

From the sound of it, you are already using best practices.  We always remove all rights and privileges from Everyone as well.  In addition, Everyone should be removed from access via the client.  That is, go to the root level, Access Rights, and make sure Everyone is not in that list. 

However, it's generally OK (preferable) to allow Everyone to have Volume access.  Now we go a little deeper.  Access to material in Laserfiche is primarily controlled via the folder structure.  You can additionally control access through the volumes, and this is often done for very sensitive areas like HR.  But, Volume access should be viewed as extra layer of protection, and not your main means of controlling access. 

If your folder access rights are set up correctly, you really don't need to restrict Volume access.  Keep in mind that for Volume access to work properly, documents have to be added to the right volume.  This is harder to control than folder access, which is hierarchical.
