Good day Stephenson, 

Based on the error message OwaUserHasNoMailboxAndNoLicenseAssignedException, it appears that the account you're using to sign in to Outlook on the web doesn't currently have an Exchange Online mailbox or an Exchange Online license assigned. 

To resolve this issue, please contact your school's IT administrator and ask them to verify that your account has the appropriate Microsoft 365 license with Exchange Online enabled.  

Note: In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support  

Your IT administrator can review your account by signing in to the Microsoft 365 admin center, navigating to Users > Active users, selecting your account and review the Licenses and apps section to ensure the correct license is assigned and all necessary apps are enabled. 

Additional information is available in the following resource: Assign or unassign licenses for users in the Microsoft 365 admin center - Microsoft 365 admin | Microsoft Learn 

I hope this information is helpful. If you have any questions or need further support, please don’t hesitate to reach out at any time. 

Thank you for your patience and understanding.
