Question details
The user wants to stop Microsoft Office 2019 Professional Plus from automatically signing in with a school account instead of their personal account.

- Product
- Microsoft Office 2019 Professional Plus
- Device & OS
- not provided
- Scenario
- Attempting to use a personal account on a potentially organization-licensed version of Office 2019 at home.
- Observed behavior
- After signing in with a personal account, the sign-in button remains visible, and the application reverts to the school account after restarting Word.
Ensure you have your personal Microsoft account credentials ready and verify the original source or proof of purchase for your Office 2019 Professional Plus product key.
Verify License Validity and Contact Administrator
Office Professional Plus is typically a corporate edition, so you must ensure your product key is valid for personal use without organizational overrides.
Microsoft Office Professional Plus is designed for organizations and is not generally sold to private individuals. A purchased product key alone does not establish valid ownership if it was obtained outside authorized channels.
Organizational licensing often enforces built-in account policies that force the software to recognize a school or work account, overriding any personal account inputs.
Verify the source of your product key to ensure it was legally purchased for home use, such as through the Microsoft Home Use Program.
Contact the IT administrator of the school or organization that originally purchased the volume license to see if organizational account policies can be removed.

Clear Cached Office Credentials in Windows
Removing cached credentials can prevent Office from automatically fetching and reverting to a previously saved school account.
Disconnect the School Account from Windows Settings
Windows may be feeding the school account directly to Office via system-level account integration.
Switch to WPS Office for a Hassle-Free Personal Experience
If your Office 2019 Professional Plus license is tied to strict organizational policies and invalid for personal use, avoid the headache and switch to WPS Office. It provides a lightweight, free, and fully compatible alternative designed for everyday users.
- 1. Download the installer: Visit the official WPS website and click the free download button for your operating system.
- 2. Install the software: Run the downloaded installer and follow the quick setup wizard to install WPS Office on your computer.
- 3. Open your files directly: Launch WPS Office and open your existing Word, Excel, or PowerPoint files without dealing with mandatory school account sign-ins.

Frequently Asked Questions
Why does Office Professional Plus require an organizational account?
Office Professional Plus is a volume-licensed corporate edition designed specifically for businesses and educational institutions. It is tied to organizational policies that often mandate a work or school account for activation and access.
Can I use Office 2019 Professional Plus legally at home?
Generally, it cannot be purchased legally by a home user as a standalone product. The exception is if it was obtained through an official employer program like the Microsoft Home Use Program. Keys bought cheaply online from third parties are often unauthorized volume licenses.
How do I completely remove a school account from my computer?
To remove a school account from your device globally, go to Windows Settings > Accounts > Access work or school. Click on the school account and select 'Disconnect', then restart your computer.
Will reinstalling Office fix the school account sign-in loop?
Reinstalling Office usually will not fix the issue if the product key itself is tied to a volume license or if the school account credentials remain cached in the Windows Credential Manager.
