I have a Microsoft 365 account. When I go to Outlook, it shows an error, and the Outlook app is also not showing in the Office portal.

    Hi @Agami Technologies ,

    Thanks for your reply.

    Microsoft 365 Apps for Business subscription includes the desktop versions of Word, Excel, PowerPoint, and Outlook. You can install these apps on up to five mobile devices, five tablets, and five PCs or Macs per user.

    Microsoft 365 Apps for Business does not include a user mailbox by default.

    While the Outlook application is included, a user mailbox is not automatically included with the Microsoft 365 Apps for Business subscription. The ‘user mailbox’ is an Exchange Online license that needs to be assigned by the global admin. If you need email functionality, you’ll need to assign an Exchange Online license separately.

    If you have any further questions about Microsoft 365 subscriptions, I recommend contacting Microsoft’s billing team for more specific details

    Hi @Agami Technologies ,

    The error message "UserHasNoMailboxAndNoLicenseAssignedError" indicates that this is a license issue. It could be the admin has not assigned Exchange online license to your account yet, or in some cases it could be your admin has made a change lately in license settings.

    Please contact your admin to let him assign the license to you:

    1. In the admin center, go to the Users > Active users page.
    2. Select the row of the user that you want to assign a license to.
    3. In the right pane, select Licenses and Apps.
    4. Expand the Licenses section, select the boxes for the licenses that you want to assign, then select Save changes.
