Fix Outlook and To Do Missing Exchange Online Access
Question details
The user is unable to access Outlook and Microsoft To Do with a school account due to a missing Exchange Online mailbox or license error.

- Product
- Microsoft Outlook and To Do
- Device & OS
- not provided
- Scenario
- Adding a school account to a personal Microsoft 365 setup.
- Observed behavior
- Outlook and To Do report that the account has no Exchange Online mailbox or license. The account logs in successfully at Outlook.com but fails at Outlook.office.com.
Ensure you know the exact login credentials for both your personal Microsoft account and your school account, as mixing them up during sign-in is a common cause for this issue.
Verify Account Type and Sign-in Credentials
Ensure you are signing in with the correct account type (Work or School) rather than a Personal account to access enterprise services.
Microsoft distinguishes between Personal accounts (used for Xbox, Outlook.com, etc.) and Work/School accounts (managed by an organization). Logging into a business portal with a personal account alias often triggers license errors.
Open your web browser, go to Office.com, click on your profile picture in the top right corner, and select 'Sign out'.
Press Ctrl + Shift + Delete in your browser to clear cached images and cookies, preventing automatic sign-in with the wrong account.
Navigate to Outlook.office.com. Enter your school email address. When prompted to choose between a 'Personal' or 'Work or school' account, strictly select 'Work or school account'.

Contact Your School IT Administrator
Verify that your educational institution has properly assigned an Exchange Online license and provisioned a mailbox for your account.

Frequently Asked Questions
Why does my school account work on Outlook.com but not on Outlook.office.com?
Outlook.com is a service designed for personal Microsoft accounts. If your account works there, it is being recognized as a personal account. Outlook.office.com requires an enterprise or education Exchange Online license, which is managed by your school.
Can I use my personal Microsoft 365 Family setup to give my school account Exchange access?
No. Personal Microsoft 365 subscriptions (like Personal or Family) cannot be applied to school or work accounts. Your school account relies entirely on the commercial or educational licenses provided by your institution.
How do I check if my Microsoft To Do sync is blocked by my organization?
Microsoft To Do relies on an active Exchange Online mailbox to store tasks. If your IT administrator has disabled To Do for the organization or has not assigned you an Exchange license, the app will fail to connect or sync.
