Hi Ava,
To help narrow this down, could you please confirm:
- When you open the Excel desktop app, what exact error message do you receive?
- Does the issue occur only in Excel, or are other Office apps (such as Word, PowerPoint, or Outlook) affected as well?
- In File > Account, does your school account appear as signed in, and does Office show Product Activated, Unlicensed Product, or a message asking you to activate Office?
In the meantime, you can also check the licensing details first:
1/ Sign in to My account page with your school account and go to Subscriptions.
2/ Check whether your assigned license includes Microsoft 365 Apps or Office desktop apps.
If you do not see Office desktop apps included in the license, or there is no Download/ Install Office option in Apps and devices tab available, it's possible that your school account has only been assigned a license that allows access to the web versions of Office. In that case, you would need to contact your school's IT administrator to confirm whether you're entitled to use the desktop Office applications and, if so, whether the appropriate license can be assigned to your account.
On the other hand, if your license does include Office desktop apps and the Download Office option is available, then the issue is more likely related to activation, sign-in, cached credentials, or account conflicts on the device. In that case, you may consider trying the troubleshooting steps outlined in the AI answer.
I hope this information is helpful. Let me know if you have any questions.
