Can't register for event: Microsoft Agent-a-thon - Level 3 Master: Build enterprise-grade AI Agents Where: Online

Event registration issues of this type (reCAPTCHA not validating, Sign in/Submit button not redirecting correctly) must be handled by the event or platform support team; there is no configuration or client-side fix documented in the provided context.

Use the official Microsoft credentials/support channel for event and exam-style registration problems and open a support request describing:

1. Event name and ID: “Microsoft Agent-a-thon - Level 3 Master: Build enterprise-grade AI Agents” and the event ID from the URL.
2. Exact behavior: reCAPTCHA not completing and/or Sign in button redirecting to an invalid or unexpected URI.
3. Browsers and devices already tried (desktop and mobile, different browsers) and that cache/cookies have been cleared.

Support can check for:

• Known issues with the registration page configuration (including redirect URI misconfiguration).
• Account-specific blocks or anomalies.
• Backend errors logged when the registration attempt is made.

If the event is associated with a specific program (for example, a certification, startup, or community program), also check that program’s discussion or support forum and post the issue there so the owning team can correct the registration form.
