[Technical Watch] 🔒 End of SharePoint and OneDrive OTPs for guests

  • 5 days ago

Microsoft is gradually phasing out external shares based on OTPs (One-Time Passcodes). Specifically:

❌ Anonymous links will no longer work

👉 External users will need to be invited as guests in Entra ID (Azure AD B2B)


⚠️ The problem: many service providers haven't anticipated this change. The result? Your external sharing could stop overnight.

✅ Immediate audit of external access

✅ Migration to Entra B2B

✅ Application of security policies (MFA, Conditional Access)


💡 Strategic advice: turn this constraint into an opportunity to secure your long-term exchanges with your partners, but always keep in mind that external sharing should remain exceptional, limited in time, and used only when necessary, as it constitutes an entry point to your IS.


⏱ Don't let July 2025 become an operational stress: act now!
