Question

AADSTS16000 blocks Microsoft for Startups 2026 onboarding and Program Support access

Çiğdem Tunçkanat 0

I am onboarding to Microsoft for Startups through the new 2026 experience. I registered with a personal Microsoft Account that has never had an Azure account or subscription. I selected “Continue without a code” and reached the Microsoft for Startups dashboard.

When I click “Set up Azure,” I receive: AADSTS16000: User account from identity provider 'live.com' does not exist in tenant 'Microsoft Services'.

I receive the same error when I try to access Help + Support in Azure Portal, so I cannot submit a Program Support request through the official support channel.

I have already tried signing out/in and using a private browser session.

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

Additional context that may be relevant:

In 2024, I signed into the previous Microsoft for Startups / Founders Hub experience using my LinkedIn account. I did not submit a startup application at that time.

I am now using the new 2026 onboarding experience with a personal Microsoft Account, as instructed by the current application flow.

Could there be a legacy Founders Hub / LinkedIn profile or identity association from 2024 causing a conflict with the provisioning of my new Microsoft Account? If so, could the Microsoft for Startups team check whether a legacy profile exists and whether it needs to be linked, migrated or cleared?

For Microsoft for Startups, Program Support is the correct path for onboarding, Azure credit activation, benefit redemption, billing profile issues, entitlement corrections, and portal access problems.

Since Help + Support in Azure Portal is also blocked, use the Microsoft for Startups program-specific support entry point instead: https://aka.ms/startuphelp-mfs-portal

Relevant supported facts for this scenario:

The Azure Portal is the primary Microsoft for Startups experience for members who joined after May 29, 2026.
Program Support handles portal access problems and onboarding issues.
If unable to determine which account was used to activate credits, or if account/entitlement help is needed, a Microsoft for Startups support ticket is the documented route.
Azure technical issues normally go through Azure Portal > ? > Help + support > Create a support request, but program-specific issues use the startup support portal instead.

If the account was created with a personal Microsoft account and Azure access is failing with AADSTS16000/AADSTS50020-style behavior, the documented Q&A guidance is that a personal Microsoft account can end up in the Microsoft Services tenant, which does not provide the directory access needed for Azure administrative actions. In that case, Microsoft for Startups Program Support is the appropriate team to review onboarding/account provisioning and next steps.
