Urgent: Agents League Hackathon access and Microsoft Foundry project creation issue

Dear Support Team,

I am participating in the Microsoft Agents League Hackathon, Reasoning Agents track, and I need help resolving an account/access issue before the submission deadline.

I originally registered for the hackathon using my personal Microsoft account/Gmail address. I can access the Innovation Studio hackathon portal with that account, but when I try to access some Microsoft applications, I receive the following error:

AADSTS500200: User account is a personal Microsoft account. Personal Microsoft accounts are not supported for this application unless explicitly invited to an organization.

I also registered again using my university organisational account:

[[Moderator note: Personally Identifiable Information removed]@utas.edu.au] University of [Moderator note: Personally Identifiable Information removed]

With my [Moderator note: Personally Identifiable Information removed] account, I can open Microsoft Foundry at ai.azure.com and see the “Create project” option. However, when I try to create a Microsoft Foundry project using my Azure for Students subscription, the deployment fails with a region/policy restriction error:

InvalidTemplateDeployment / RequestDisallowedByAzure

The error says the Foundry resource was disallowed because the subscription policy only allows selected deployment regions. I tried multiple regions including East US 2, Australia East, East US, West US, West US 3, Sweden Central, France Central, and UK South, but all failed.

I also cannot currently use the Discord support channel due to account/access issues.

Could you please help with one of the following:

Confirm which account I should use for the hackathon submission and Microsoft Foundry access.

Help activate or link my [Moderator note: Personally Identifiable Information removed] organisational account to my hackathon registration.

Advise which Azure region is allowed for Microsoft Foundry under my Azure for Students subscription.

Provide an alternative way for hackathon participants to access Microsoft Foundry if Azure for Students is restricted.

My project is already being developed locally with synthetic data, GitHub, and a Streamlit prototype, but I need Microsoft Foundry access for the final competition integration.

Thank you for your support.

Kind regards,

    For the hackathon scenario described, the available information only supports the following guidance:

    1. Personal vs organizational account
      • The error AADSTS500200: User account is a personal Microsoft account. Personal Microsoft accounts are not supported for this application unless explicitly invited to an organization means the application being accessed only accepts work/school (Microsoft Entra ID) identities, or personal accounts that have been explicitly invited into an organization.
      • When a domain (such as a university domain) is hosted in Microsoft Entra ID, new personal Microsoft accounts (MSA) cannot be created using that work/school email address, and Microsoft is limiting the use of personal Microsoft accounts linked to work/school domains when those domains are configured in Microsoft Entra ID.
      • In environments where both a personal MSA and a work/school account exist with the same email, this can cause sign-in confusion and access issues.
    2. Which account to use
      • For applications that show AADSTS500200 and are configured for work/school accounts, the organizational (university) account must be used, not the personal MSA.
      • If the hackathon or related portals require a personal MSA but the email domain is also used as a work/school domain in Microsoft Entra ID, the recommended pattern in Microsoft guidance is to:
        • Use a separate personal email address (for example, a non‑university address) as the personal Microsoft account username, or
        • Rename the existing personal Microsoft account so it no longer uses the work/school address as the sign‑in name.
    3. Handling overlapping personal and work identities
      • Microsoft guidance for overlapping personal and work identities (same email on both MSA and Entra ID) is to rename the personal Microsoft account so that the work/school address is not used as the MSA username. This avoids conflicts when accessing business or organizational services.
      • The documented steps to rename a personal Microsoft account are:
        1. Sign in to the Your Info page of the Microsoft account.
        2. Select Manage how you sign in to Microsoft.
        3. Under Account alias, add a different personal email address (or get a new Outlook.com address) or a phone number.
        4. Make the new alias the primary sign‑in name.
    4. Subscription region/policy restrictions
      • The context provided does not include any authoritative list of allowed regions or specific policy behavior for Azure for Students subscriptions with Microsoft Foundry.
      • It only states that Microsoft Foundry is available in most regions where Foundry Tools are available and that region support is documented separately.
      • It does not contain details on subscription‑level policy restrictions (such as which regions are blocked for a specific offer like Azure for Students) or how to override them.
    5. Support and escalation options
      • For technical product questions about Foundry Tools (including development and deployment issues), Microsoft Q&A is the documented community support channel. Questions can be posted there using the appropriate tags (for example, the Foundry Tools tag) to get input from Microsoft engineers and the community.
      • For account sign‑in issues in general (personal Microsoft account vs work/school account), Microsoft provides:
        • General sign‑in troubleshooting and recovery guidance for Microsoft accounts.
        • Guidance on overlapping MSA and work/school identities and renaming personal accounts.

    Because the context does not include hackathon‑specific rules, no definitive statement can be made here about which identity the hackathon organizers require for submission, how to link a specific university account to a specific hackathon registration, or which exact Azure regions are permitted for a particular Azure for Students subscription. Those details depend on the hackathon’s configuration and the policies on the specific Azure subscription, which are not described in the provided material.

    The only supported actions from the available information are:

    • Use the university (work/school) account for applications that reject personal MSAs with AADSTS500200.
    • Avoid using a work/school email as the username of a personal Microsoft account when the domain is hosted in Microsoft Entra ID; instead, rename the personal account to a different email or phone number.
    • Use Microsoft Q&A with the Foundry Tools tag for Foundry‑specific technical questions, including deployment and region issues.
    • Use the documented Microsoft account help and recovery resources for any personal Microsoft account access problems.
