I am getting this message

AADSTS500200: User account '******@outlook.com' is a personal Microsoft account. Personal Microsoft accounts are not supported for this application unless explicitly invited to an organization. Try signing out and signing back in with an organizational account.

    Sign in to Outlook.com with the account’s Personal account option; if the error appears only after opening an organization’s application or link, that organization must grant the personal account guest access or you must use its work/school account.

    For personal Outlook.com access

    1. Sign out of all Microsoft accounts in the browser.
    2. Open an InPrivate/Incognito window to prevent an existing work/school session from selecting the wrong account.
    3. Go to the Microsoft account sign-in page and enter the @outlook.com address.
    4. If prompted to choose an account type, select Personal account, not Work or school account.
    5. Open Outlook from the Microsoft account page.

    An Outlook.com address is a personal Microsoft account. Microsoft documents personal and work/school accounts as separate account types with different sign-in paths.^1^ Trying a private browser session is also the documented way to rule out an active session using the wrong account or tenant.^2^

    If private browsing works, clear the Microsoft sign-in cookies/site data in the normal browser, then sign in again as a personal account.

    If an organization’s application shows the error

    The application is not currently accepting that personal account directly. Use one of these routes:

    • Sign in with the work or school account issued by the organization.
    • Ask the organization’s administrator to invite the exact Outlook.com address as a B2B guest.
    • After receiving the invitation email, select Accept invitation and sign in with that same personal account.^3^

    Microsoft Entra workforce tenants can allow personal Microsoft accounts as B2B guests, but the account must enter through an invitation or configured sign-up flow.^4^

    If this happens on the normal Outlook.com website even in a private window—not after following an organization’s link—record the Request ID, Correlation ID, and Timestamp shown under troubleshooting details and contact Microsoft Support. Do not post those identifiers publicly.
