Unable to Access Microsoft for Startups Portal, Redirected Back to Login Screen After Authentication

Hello,

I am experiencing an issue accessing the Microsoft for Startups portal.

When I navigate to https://portal.startups.microsoft.com/login and select "Sign in with your Microsoft account," the authentication process appears to complete successfully. However, instead of accessing the portal dashboard, I am redirected back to the login screen.

I have already attempted the following troubleshooting steps:

• Cleared browser cache and cookies • Used an Incognito/Private browser window • Tried multiple browsers • Confirmed I am using the correct Microsoft account

Despite these efforts, the issue persists.

Could you please verify whether my Microsoft account is properly associated with my Microsoft for Startups profile and advise on any additional steps required to resolve this issue?

I have attached a screenshot of the login page for reference.

Thank you for your assistance.

Kind regards,

Clayton Purdy

    The behavior described (successful authentication but returning to the login page) is consistent with a sign-in or account-association issue on the Microsoft side rather than a browser problem, especially after clearing cache, trying InPrivate/incognito, and using multiple browsers.

    From the available information, the Microsoft for Startups experience is managed through the Azure portal for eligible accounts. The portal is the gateway to manage the Microsoft for Startups subscription, credits, and benefits. If sign-in loops back to the login page, it typically means either:

    • The Microsoft account being used is not (yet) associated with an active Microsoft for Startups program profile/tenant, or
    • There is a backend issue with the program experience for that account that must be corrected by Microsoft support.

    Because account association and tenant eligibility cannot be verified or changed from the client side, the next step is to open a support request from the Azure Portal (if accessible with that account) or via Microsoft support channels and ask them to check:

    1. Whether the Microsoft account is linked to a valid Microsoft for Startups enrollment.
    2. Whether the correct tenant and subscription are provisioned and active for that account.
    3. Whether any program changes (for example, the new post–May 29, 2026 experience) require migration or a different sign-in path for that account.

    If the Azure Portal can be accessed with the same Microsoft account, submit a support request there under the Microsoft for Startups program, describing the sign-in loop and requesting verification of the account’s association with the Microsoft for Startups subscription.

    If the Azure Portal cannot be accessed at all with that account, contact Microsoft support and request that they verify and fix the Microsoft for Startups association for the specific Microsoft account and tenant.
