Microsoft Azure Cognitive Services Email Verification Failing

Hi Dan A,

Thank you for reaching out to Microsoft Q&A.

Based on your description, I understand that after submitting a Unified Gating request for Anthropic models in Azure AI Foundry, you received the Microsoft email asking you to verify your email address. However, when you click "Verify email address", you're redirected to https://3pc.microsoft.com/vetting/ and receive the message:

"The request is blocked."

As a result, you're unable to complete the email verification and are stuck in a verification loop.

Based on the available Microsoft guidance, the most common causes are related to the email address being verified, the validity of the verification link, or email delivery.

What to check

1. Confirm you're using a valid organizational email address

Microsoft's identity verification guidance recommends using an email address that can be validated for your organization. Verification may fail if the request was submitted using:

• Distribution list addresses (for example, admin@, info@, or sales@)
• Personal email domains (such as @gmail.com, @hotmail.com, etc.)
• Email domains that aren't associated with the organization being validated

If applicable, verify that the request was submitted using an organizational email address.

2. Check whether the verification link has expired

The email indicates that the verification link is valid for 7 days. If the link has expired, it can't be reused, and you'll need to submit a new verification request or resend the verification email.

3. Verify email delivery and mail filtering

Even though you've received the verification email, it's worth checking whether your mailbox or organization is affecting the verification process.

We recommend:

• Checking your Junk/Spam folder.
• Reviewing mailbox rules or email security policies that may block Microsoft verification emails.
• Allowlisting Microsoft email domains if your organization uses email filtering.

4. Try creating a new verification request

If the link has expired or continues to fail, initiate a new verification request (or resend the verification email if that option is available). This will generate a new verification link.

About the "The request is blocked" message

The current Microsoft documentation primarily covers common verification issues such as email eligibility, email delivery, and link expiration. It does not provide specific troubleshooting steps for the "The request is blocked" page displayed at https://3pc.microsoft.com/vetting/.
