Microsoft Partner Center account is a Hotmail account from way back and doesn't have owner/admin access to Workspaces

Partner Center requires a work account in a Microsoft Entra ID tenant; a personal Hotmail/Microsoft account cannot be used as the identity that owns or administers Partner Center workspaces.

Key implications for this scenario:

1. Work vs personal account
   • A valid Partner Center admin/owner must be a work account such as ******@yourcompany.com or ******@yourcompany.onmicrosoft.com, associated with a Microsoft Entra tenant.
   • Personal accounts like Hotmail/Outlook.com are not supported for Partner Center access going forward and cannot be used as the basis for proper workspace ownership and role management.
2. Confirm current access and roles
   • Sign in to Partner Center and go to Settings (gear icon) → Account settings → My access.
   • Review which workspaces are visible and which roles are assigned. If the Hotmail-based sign-in is actually mapped to a work account in Entra, the roles shown here determine what can be seen or managed.
3. Use the correct work account and request access
   • Ensure sign-in is with the correct work account (not the personal Hotmail account) if both exist and look similar. For example, ******@contoso.com might exist both as a personal and as a work account.
   • If the expected Partner Center capabilities (Microsoft AI Cloud Partner Program, CSP, Marketplace, etc.) are not visible, use My access to see who the Account admin, Owner, or Manager contacts are, and request the appropriate role assignment for the domain account that was recently added.
4. Assign roles to the new domain account
   • An existing Account admin, Global admin, User management admin, or the Owner/Manager of the relevant program (Marketplace, Microsoft 365 and Copilot, etc.) must:
     • Create or locate the new domain-based work account in the tenant.
     • Assign the necessary Partner Center roles to that account so it can administer the required workspaces.
   • Role changes made in the Azure portal can take up to one hour to propagate to Partner Center.
5. If no admin/owner is available
   • If the original owner/admin associated with the Partner Center account is no longer available and there is no active owner in the seller account, an Admin or Account Admin must submit a support request to have ownership updated. The request must include:
     • Organizational consent to update the owner.
     • The Microsoft Entra ID details (email of the proposed new owner, tenant name, and tenant ID) from the Tenants page under Account settings.
6. When sign-in or account access is blocked
   • If there are issues signing in or recovering access (for example, no global admin available, or only one global admin and it is inaccessible), follow the account access escalation paths described in the sign-in troubleshooting guidance (for example, contacting the appropriate Data Protection team or support channel for the tenant type).

In practice, the viable path is to ensure a proper work account in Microsoft Entra ID (your domain account) is granted the necessary Partner Center roles by an existing admin/owner or via a support-assisted owner update. The legacy Hotmail identity itself cannot be converted into a supported Partner Center admin identity.
