# We opened a case with Microsoft and finally fixed this same issue using this:
# Verify if web application / site has document ID enabled

$web=get-spweb URL

$web.properties

# How to fix if documentID_enabled is set to 0:

$web=get-spweb URL

$web.properties[“docid_enabled”]=”1”

$web.properties.update()
