When I process a payment via Mekorma RPS I receive the error: "User does not have access to integration base folder"

Please login to GP as 'sa' and go to the Mekorma RPS Integration Window.
 
Locate the Integration Base Folder path.
 
Confirm with IT that users have Full Permissions to the Base Folder.
 
Note: We recommend setting up the folder with a UNC path.
