How to Sign In to a Personal Microsoft 365 Account Instead of a Work Account
Question details
The user is unable to access a newly purchased personal Microsoft 365 subscription because their browser automatically signs into an old work account.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to sign in to a personal Microsoft 365 account online to access a newly purchased subscription.
- Observed behavior
- The web browser automatically selects and logs into a previously saved work account, preventing access to the personal account and its associated subscription.
Verify that you have the correct email address and password for your newly purchased personal Microsoft 365 account ready before attempting these troubleshooting steps.
Clear Browser Cache, Cookies, and History
Clearing outdated stored data ensures your browser does not automatically authenticate using old work credentials.
Web browsers often store session cookies and cache data to speed up future logins. If you previously signed into a work account, the browser may use this saved data to bypass the login screen automatically.
Open your web browser (e.g., Google Chrome) and click the three-dot menu in the top right corner, then select 'Settings'.
Navigate to the 'Privacy and security' section on the left sidebar and click on 'Clear browsing data'.
Check the boxes for 'Cookies and other site data' and 'Cached images and files'. Set the time range to 'All time'.
Click the 'Clear data' button. Once finished, restart your browser and navigate to the Microsoft 365 login page to enter your personal account credentials.
Sign In Using a Private or Incognito Window
A private browsing window ignores existing cookies and active sessions, allowing an immediate fresh login attempt without clearing your primary browser data.
Remove Saved Autofill Entries for the Work Account
Browsers may automatically fill in old work account passwords. Deleting these saved credentials prevents unwanted automatic logins.

Frequently Asked Questions
Why does Microsoft 365 keep defaulting to my work account?
Your web browser stores session cookies and cached credentials from your previous logins. If you were recently signed into your work account, the browser attempts to use that active session to authenticate automatically, skipping the manual login screen.
Can I merge my personal and work Microsoft 365 accounts?
No, Microsoft does not allow personal accounts and work/school accounts to be merged. They are hosted on entirely different infrastructures (Microsoft Account vs. Entra ID/Azure AD). You must sign out of one to access the other, or use separate browser profiles.
How do I permanently remove a work account from my Windows PC?
Go to Windows Settings > Accounts > 'Access work or school'. Find your old work account in the list, click on it, and select 'Disconnect'. This will remove the account's credentials and policies from your device.
Will clearing my browser cache delete my Microsoft 365 documents?
No, clearing your browser cache and cookies only removes local temporary files and stored login sessions from your web browser. Your Microsoft 365 documents are safely stored in OneDrive or SharePoint and will not be affected.
