Microsoft for Startups onboarding blocked – LinkedIn verification button does nothing and support portal returns AADSTS16000

Anna Huth 0

Hello Microsoft Support Team,

I am trying to register my startup, team4set (https://team4set.com), for the Microsoft for Startups program.

Unfortunately, I am completely blocked during onboarding.

Issue 1 – LinkedIn verification

My dashboard displays the option to unlock $200 in Azure credits by verifying my LinkedIn profile. However, clicking "Verify with LinkedIn" does absolutely nothing.

No pop-up, redirect or error message appears.

I have already:

Tried Google Chrome.

Signed into LinkedIn separately.

Enabled pop-ups and redirects.

Refreshed the portal and retried several times.

Issue 2 – Support access

When I try to access Azure Help & Support, I receive:

AADSTS16000: User account from identity provider 'live.com' does not exist in tenant 'Microsoft Services'.

The message says that my account needs to be added as an external user to that tenant.

I cannot submit a support request because I cannot authenticate.

My details:

Startup: team4set

Website: https://team4set.com

Microsoft account: [registered Gmail address]

Country: Germany

I have found another Microsoft Q&A report dated October 26, 2026, describing exactly the same combination of issues.

Could a Microsoft moderator please escalate this to the Microsoft for Startups onboarding/identity team?

I would appreciate an investigation of the LinkedIn verification process and assistance activating my startup account.

This is a program onboarding issue, not an Azure workload or billing issue.

Your onboarding is blocked by two identity-path failures: LinkedIn verification callback is not completing in dashboard, and support portal access is failing with AADSTS16000 due to account-session conflict across Microsoft identities.

Use an InPrivate session and sign in only with the exact startup program account (avoid mixed personal/work account cookies).

Retry LinkedIn verification from dashboard after clearing stale auth state; ensure popup/redirect is not blocked by browser settings.

For AADSTS16000, confirm tenant/account type expected by the support portal and switch directory before opening support links.

Capture correlation ID, trace ID, timestamp (UTC), and the failing URL for both LinkedIn and support portal failures.

Request manual onboarding/support channel enablement from Startups program team using your existing case metadata.

Validation checks:

LinkedIn verification completes and status updates in Startups dashboard.

Support portal opens without AADSTS16000 for the same account context.

Thanks - I have already enabled pop-ups and redirects, signed into LinkedIn separately and retried the verification process in Chrome.

I also tested using a completely clean Incognito session with only my personal Microsoft account signed in and the problem persists.

Also my Azure directory settings show no additional directories available to switch to. My account is a personal Microsoft Account (live.com identity provider), not an organizational Entra ID account. The AADSTS16000 error occurs specifically when accessing the Azure Support portal.

The LinkedIn verification button itself remains completely unresponsive, without opening a new window or displaying an error.

Could this issue please be escalated to the Microsoft for Startups onboarding team for manual investigation?

I would particularly appreciate assistance with:

Resetting or manually completing the LinkedIn identity verification.

Enabling access to the appropriate Microsoft for Startups Program Support channel.

Thank you.

Update – Issue persists after all recommended troubleshooting steps

Additionally, I have confirmed that the Azure Help & Support portal continues to return AADSTS16000, even in a regular browser session.

Latest error details:

Error: AADSTS16000

Identity provider: live.com

Tenant: Microsoft Services

Trace ID: 61e7a520-889b-4486-a63c-6c3e1a637d00

Correlation ID: b4077469-3bd9-4ec1-8dbd-99aea36fcb98

Timestamp: 2026-11-10 16:00:42 UTC

I also attempted to use the dedicated Microsoft for Startups support request link, but it redirects me to the general Azure Help & Support portal, which I cannot access because of the same authentication error.

At this point, I believe this requires direct intervention by the Microsoft for Startups Program Support / Identity team.

Could a Microsoft moderator please escalate this case internally or provide an alternative private support channel that does not require authentication through the affected Azure Support portal?

I cannot complete onboarding or access any program benefits until this issue is resolved.
