Microsoft Azure Cognitive Services Email Verification Failing

Dan A 40

I am using Azure Foundry for the first time. I submitted a quota request for Anthropic models. I received an email from Microsoft (See copy below). When I click verify email address, I keep getting "The request is blocked.

20260714T020350Z-r1d677ddcdbvkb9shC1MSP39c80000000k0g00000000c17y". The url it takes me to is "https://3pc.microsoft.com/vetting/". Thhis has me stuck in a loop. Any help would be appreciated.

Hello,

We need to verify your email address.

You are receiving this email because you recently applied for Microsoft Azure Cognitive Services Unified Gating.

As part of our ongoing effort to keep your identity and privacy protected, we need to verify that you signed up for the program and provided this email address for contact and verification purposes.

If you did not register for our program using this email address, please disregard this email.

I did not register for anything using this email address.

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/.

Please refer this

Resolve common email verification issues in Azure Trusted Signing (same article content shown): https://learn.microsoft.com/azure/trusted-signing/faq

I Hope this helps. Do let me know if you have any further queries.

Thank you!

The verification link is only 24 hours old, I am using a valid org email and I just tried a different org email to create a new verification email which had the same response. I tried incognito and I tried using my personal phone. I verified that the domain can be reached from my computer and nothin on my end is blocking it.

Answer 1

Same here. I've tried 3 browsers, multiple quota request/verification emails, multiple machines, no adblockers/etc. Countless incognito/private tabs to rule out cache/cookies. Tried verifying my assigned-to-me email address at our organizational subdomain (@its.company.edu) and even my global admin account at our naked domain (@company.edu), not a list and not a shared mailbox. Same behavior from multiple WAN connections. URL not being rewritten by our email filters. No matter what, verification links DO NOT WORK and our quota requests get declined.

Microsoft, this is BROKEN!

I even emailed the dedicated support email listed on the initial quota request (msazureopenai@microsoft.com), and that went entirely unanswered/ignored.

Hi, the 3pc.microsoft.com page is part of the verification handoff, so a block there can create exactly this loop. Please try the link in an InPrivate window with tracking protection temporarily relaxed for Microsoft domains, and test from a different network without a corporate proxy, DNS filter, or ad blocker. Also make sure the link has not expired; request a fresh verification email instead of reusing the old URL. If it still fails, this needs Microsoft support because the correlation ID can identify the backend transaction. Share the correlation ID and timestamp privately in the support case, not the full verification URL or token here.

I already tried incognito and accessing it from my personal phone to rule our any security blocks. The link is only 24 hours old but I tried using another org email to do the same request and had the same problem when I tried the verification

Support case: cannot find a relevant category for this issue.

I just received the "Action needed: Verify your email account with Microsoft" link and same thing is happening to me as well. I tried incognito, turn off ad-blockers, went on mobile network, tried normal and private browsing -- nothing worked. Can someone take a look please?
