I’ve been testing bulk Outlook account creation over the past few days, and Microsoft’s anti-abuse system is a lot stricter than I expected.
Same IP and same browser fingerprint? You’re lucky to get 3–5 accounts before hitting captchas or outright bans.
What’s been working better for me:
- Rotating proxies (each task gets a unique IP)
- Different browser/device fingerprints
- Using virtual number services for phone verification
With this setup, bulk runs are way more stable. Anyone else noticing new security changes on Outlook lately?
