A subscriber site collection receives several custom document content types published from the content type hub. An admin sets one of those published content types as the default on a library, then enables the Document ID Service site collection feature. Afterward, documents in that library still aren't getting Document IDs and the Document ID column doesn't appear. What is the correct fix?
Correct answer: A. Enable the Document ID Service feature on the content type hub site collection, then republish the content types.
Content types published from the hub are set to read-only on subscriber sites, so the Document ID Service cannot provision its required columns onto them. The documented fix is to enable the Document ID Service on the content type hub site collection itself, then republish the syndicated content types so subscribers receive the updated, Document ID-enabled content types.
Why the other options are wrong:
- B. The blocker is the read-only published content type, not the choice of Document vs custom type; reverting does not provision IDs on the custom content type.
- C. Breaking inheritance is not the documented remedy and fragments the published content type; enable the feature at the hub and republish instead.
- D. The issue isn't a stalled timer job; the published content type is read-only and lacks the Document ID columns until the hub is updated and republished.
Memory hook: Published = read-only; turn on Doc ID at the hub, then republish.
