Question details
The user is unable to sign in to Microsoft Office using a personal Microsoft 365 Family account because the system prompts for a work or school account instead.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Activating or signing into Office desktop applications using a personal Microsoft 365 Family subscription.
- Observed behavior
- Office displays an error message stating that no work or school account was found, preventing the software from activating with the personal account.
Ensure you know the correct email address and password associated with your Microsoft 365 Family subscription. If you plan to modify registry keys, it is highly recommended to back up your Windows Registry first.
Clear Cached Microsoft Credentials
Removing old or conflicting work or school credentials forces Office to prompt for a clean, new login.
If you previously used a work or school account on the same computer, Windows may have cached those login details. Office might be trying to use these saved credentials automatically instead of asking for your personal account.
Press the Windows key, type "Credential Manager" in the search bar, and hit Enter to launch the application.
Click on the "Windows Credentials" tab at the top of the window.
Scroll down to the "Generic Credentials" section. Locate any entries containing "MicrosoftOffice", "msteams", or related to your old work/school account. Click the drop-down arrow next to them and select "Remove".
Restart your computer, open an Office application like Word, and try signing in again with your personal Microsoft 365 Family account.
Verify Account via Private Browser Window
This ensures your browser is not automatically passing cached work credentials to the Microsoft sign-in page.
Clear Office Identity Cache and Registry
If the Credential Manager method doesn't work, resetting the Office identity folders and registry key will remove deep-seated account conflicts.
Switch to WPS Office for a Hassle-Free Experience
If Microsoft 365 activation issues and account conflicts are slowing you down, consider switching to WPS Office. It provides a lightweight, easy-to-use, and highly compatible alternative that doesn't require complex subscription troubleshooting.

Frequently Asked Questions
Why does Microsoft Office keep asking for a work or school account?
This usually happens because cached credentials from a previous work or school account are stored on your device. The Office activation system gets confused and tries to use those old credentials instead of recognizing your personal Microsoft 365 Family account.
Will deleting credentials from Credential Manager delete my Office files?
No, clearing credentials only removes the saved login information on your computer. Your saved documents, spreadsheets, and personal files remain completely safe and untouched.
What is a Microsoft 365 Family account?
It is a personal subscription plan that allows up to six people to share Microsoft 365 apps and cloud storage. It is distinctively different from commercial work or school enterprise accounts, which are managed by an organization's IT department.
How do I back up my Windows Registry before modifying it?
Open the Registry Editor by typing "regedit" in the Windows search bar. Click on "File" in the top menu, select "Export", choose a safe location to save the file, ensure "All" is selected in the export range at the bottom, and click "Save".
