Device & OS
not provided
Scenario
Attempting to sign in to the desktop Office app using a school-provided email address and trying to confirm if the subscription includes 1 TB of OneDrive storage.
Observed behavior

Before you start

Ensure you have a stable internet connection and have your exact school-provided email address and password ready for testing.

Solution 1Recommended

Test Account Access via Office.com in Private Browsing

Use a private browser window to bypass local cached credentials and verify if your school account is active and functioning correctly.

Sign-in loops on the desktop application are often caused by conflicting local credentials. Testing your login on the web helps isolate whether the problem is with the desktop app or the account itself.

1
Open a Private Browser Window

Launch your preferred web browser and open a private or incognito window (e.g., press Ctrl+Shift+N in Google Chrome or Ctrl+Shift+P in Edge/Firefox).

2
Navigate to Office Online

Go to Office.com and click on the 'Sign in' button located in the center or top right of the page.

3
Enter School Credentials

Type in your school-provided email address and password to attempt logging in.

4
Check OneDrive Storage Settings

If you sign in successfully, open the OneDrive web app from the app launcher (waffle icon). Look at the bottom left corner of the OneDrive page to view your allocated storage capacity.

Frequently Asked Questions

Does a school Microsoft 365 account automatically come with 1 TB of OneDrive storage?

Not necessarily. While many educational licenses include 1 TB of storage, the exact capacity is determined by your school's specific subscription plan and the limits configured by your IT administrator.

Why does the Office desktop app keep asking me which account to use?

This sign-in loop usually happens when corrupted or conflicting credentials are saved on your device. Clearing your Windows Credentials Manager or signing in via a private browser window often helps isolate or resolve the issue.

Do I need a separate activation key for my school OneDrive account?

No additional activation is required. Simply signing in to your Microsoft Office account with your valid school credentials will automatically grant you access to both the Office applications and your allocated OneDrive storage.
