Registration Error 400 (Invalid email format) - AI Skills Fest 2026

Hello Microsoft Support Team,

I am facing a 400 Bad Request error while attempting to register for the AI Skills Fest 2026 event. The platform's frontend interface appears to be passing a phone number into the email validation parameter, causing the backend API to reject the registration request.

Below are the exact technical logs collected from my browser's Developer Tools (Network Tab):

Event Code: AISF2026

Application Name: AI Skills Navigator

Profile ID: 71441a37-1f34-4487-8b14-94c33f44570b

Display Name: Mohammad Sulthan

Trace ID: 00-ac1aa2bd9ef249a48c1ad6a73dd2b237-294426c047e5c3f6-01

API Request Payload:
{

"profileId": "71441a37-1f34-4487-8b14-94c33f44570b", "eventCode": "AISF2026", "applicationName": "AI Skills Navigator", "locale": "en-US", "displayName": "Mohammad Sulthan", "email": "919884621812"

}
responce :

{

"status": 400, "title": "One or more validation errors occurred.", "errors": { "Email": ["Invalid email format"] }, "type": "https://tools.ietf.org/html/rfc9110#section-15.5.1"

}

Could you please manually update my event profile payload on the backend database or clear this account mismatch so I can complete my registration?

Thank you for your prompt assistance.

Best regards, Mohammad Sulthan: ******@gmail.com

For an event registration error like “There was a problem with registration,” support must be contacted through the official channel for that specific Microsoft program or event type.

For Microsoft Virtual Training Days or certification/credentials-related events, use the Credentials Support channel:

Go to the Credentials Support help page: https://www.aka.ms/credentialssupport (also referenced as “Credentials Support”).
Submit a support request describing the event, your registered email, and the exact error message.

If the event is part of a different Microsoft program (for example, a nonprofit or startup program), use that program’s official support form instead, such as:

Nonprofits: use the Contact Us form at https://nonprofit.microsoft.com/contactus for registration or access issues.
Microsoft for Startups: sign in to the Microsoft for Startups portal and open a support ticket from there.

Include in the request:

Event name and date.
Registration link (if available).
The email address used for registration.
Screenshot or text of the error: “There was a problem with registration.”

Support can then verify the registration status and correct any synchronization or system issues.
