Everytime I try to open Outlook I get the below error code.

I have tried clearing cookies/cache, different browsers etc. I even tried to open on a different laptop. Nothing works.

Is there a way to fix this?

    Dear Ali P.****,

    Good day! Thank you for reaching out to Microsoft community.

    As per your description, it seems like that you are unable to access Outlook and encounter the error:

    Error: 500 | Microsoft.Exchange.Clients.Owa2.Server.Core.OwaUserHasNoMailboxAndNoLicenseAssignedException | X-OWA-Error | UserHasNoMailboxAndNoLicenseAssignedError.

    This error typically indicates that your user account either lacks an assigned mailbox or is not associated with an active Microsoft 365 license that includes email services.

    This typically happens when:

    • The account is inactive or was not set up for email functionality.
    • The account is missing the required Microsoft 365 license (to be specific, license with Exchange Online Plan).
    • The user account had license then someone from the administration removed the license.
    • The user account has not been configured for OWA (outlook web application) from the admin center.
    • If the affected user account is license and OWA is configured from admin center, it could be a service incident at your location sever side.

    Troubleshoot Browser Problems:

    • A corrupted browser cache or cookies can cause Outlook Error 500. So can browser plugins if they interfere with Outlook’s connection to the Microsoft servers.
    • You can use Incognito mode or private mode to access Outlook and find out where the trouble lies. This is because private browsing modes disable cookies, site data, and plugins.
    • If this works fine with "Incognito mode or private mode", and If you can access Outlook via incognito mode, you can narrow down where the problem lies. I suggest clearing your browser "cache and deleting your cookies." for "All Time".

    Note: If you’re an end-user, please coordinate with your Office 365 Global Administrator to handle these steps.

    You need to check the license for your user, to do that follow below instruction:

    Also please take a screenshot and share it with me for the user, which license was she assigned?

    • Go to https://admin.microsoft.com and sign in to your account.
    • Goto Users > Active users.
    • Choose the name of the affected user account.
    • Under "Licenses and apps" Select Licenses.

    For example: Image

    Remove User Roles:

    • If your user account is assigned too many administrator roles, you might end up in an endless redirect loop. This can cause the “Something went wrong. Repeating redirects detected” error. Luckily, this is usually easy to fix.
    • If you’re the Global Admin for your Microsoft 365 Tenant, follow the steps to remove unnecessary admin roles from active users and fix the error.

    Enable Outlook on the Web:

    If you’re receiving the “X-OWA-Error” message, enabling the Web version of Outlook might fix your problem. This error occurs when an administrator removes your permissions to access Outlook Web.

    • Go to https://admin.microsoft.com and sign in to your account.
    • Goto Users > Active users.
    • Choose the name of the affected user account.
    • Under "Mail" Select Manage email apps.
    • Ensure the Outlook on the web checkbox is ticked.

    Please follow these steps and let me know the outcome. If the issue persists after completing the above, feel free to reach out, and we can further investigate the problem together.

    Thanks for choosing the MS community.

    Looking forward to your response and have a great day ahead!!
