Does onedrive.com block AI crawlers?
onedrive.com blocks 2 of 17 AI crawlers (Google-Extended and Applebot-Extended), and allows 14 (checked 2026-10-01).
This is the deliberate split: training crawlers are opted out, while the retrieval crawlers that fetch pages to cite them in ChatGPT search, Claude and Perplexity answers can still reach it.

How this was measured
We read onedrive.com’s robots.txt, resolved it with an RFC 9309 matcher for each crawler’s product token, then fetched the homepage once as each crawler. A 403 or a challenge page is a block even when robots.txt allows the crawler; a timeout or rate limit is “not established”, never a block. One probe, from one location, on 2026-10-01, so a rule changed since then is not reflected here. Full methodology.
Check your own site
The free checker runs the same probe on any URL: robots.txt resolved for every AI crawler, then a live fetch as each one, so a CDN or firewall block shows up even when robots.txt looks fine.
