🔧 Fix Microsoft Teams Error AADSTS50011 Instantly: Ultimate Redirect URI Guide
Encountering the frustrating Microsoft Teams Error AADSTS50011? 😩 This common Azure Active Directory (now Entra ID) error screams "The reply URL specified in the request does not match the reply URLs configured for the application." It blocks sign-ins for Teams tabs, bots, or custom apps, halting your productivity.
Don't worry! This guide delivers a Redirect URI fix that's straightforward, reliable, and battle-tested. Follow these steps to banish the error forever and dive back into seamless collaboration. Let's get your Teams app humming! 🚀
Why Does Microsoft Teams Error AADSTS50011 Happen?
The root cause? A Redirect URI mismatch. When your Teams app authenticates via OAuth, the callback URL (Redirect URI) sent in the request doesn't exactly match what's registered in your Azure app. Common triggers:
- ❌ Typos in the URI (e.g., missing slash or wrong domain).
- ❌ Platform-specific URIs forgotten (Teams requires
msteams://schemes). - ❌ Environment changes (dev vs. prod URIs swapped).
- ❌ Multi-tenant apps missing proper scopes.
Pro tip: Always verify URIs case-sensitively—Azure is picky! 🔍

| Teams Bot | https://token.botframework.com/.auth/web/redirect or msteams://auth/ |
Bot Framework standard |

Match your app's exact endpoint |

Replace <your-app-id> |
Action: Click Add a platform > Web or Mobile and desktop applications. Paste the exact URI, enable ID tokens if needed, and hit Configure. ✅
