How to trust trust a document in access via PowerShell so I can trigger my database export marcos
Microsoft Office documents, including Microsoft Access .accdb databases, need to reside in a "trusted" location in order for macros and VBA functions to run without requiring intervention from the user.

Add the desired target location to the list of trusted locations by making a change to the system registry:

HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Access\Security\Trusted Locations
