How to Sign Out Completely from Outlook on a Shared Computer
Question details
The user needs to know how to securely and entirely sign out of their Outlook account on a shared computer to prevent unauthorized access by other users.
- Product
- Microsoft Outlook
- Device & OS
- Windows
- Scenario
- Using a public or shared computer for email access and wanting to ensure no personal login data is left behind.
- Observed behavior
- Simply closing the browser or application may leave the user's mailbox accessible or keep credentials cached, posing a security risk on shared devices.
Ensure you have sent or saved any drafted emails and closed all active Office files before signing out or clearing your account credentials.
Sign Out of Outlook on the Web Completely
This is the best method if you are checking your email via a web browser on a shared or public computer.
When using Outlook on the web, simply closing the browser tab does not always end your session. You must manually sign out and clear your cached data, especially if 'Stay signed in' was accidentally selected.
Click on your profile picture or initials in the top right corner of the Outlook web interface, and select 'Sign out' from the dropdown menu.
Wait for the sign-out confirmation page to load, then completely close all active browser windows and tabs.
If you reopen the browser and your account is still listed on the Microsoft login page, click the three dots next to your account name and select 'Forget' or 'Remove'.
If you checked 'Stay signed in' previously, open your browser settings (usually Ctrl + Shift + Delete) and clear cookies and cached site data to ensure the session is fully terminated.
Remove Account from Outlook Desktop App
Use this solution if you added your personal email account to the Outlook desktop application on a shared Windows PC.

Frequently Asked Questions
Why does Outlook still log me in automatically after I click Sign out?
This happens if your web browser saved your login cookies, or if you previously checked the 'Stay signed in' prompt. You need to clear your browser's cookies and cache, or remove the saved credential from the browser's password manager.
How do I ensure my password is not saved on a shared computer?
Always use 'Incognito' or 'Private Browsing' mode when checking email on a shared web browser. If using the desktop app, ensure you delete your account from the Windows Credential Manager under 'Windows Credentials' after you are finished.
Can I sign out of Outlook on a shared computer remotely?
Yes. Log into your Microsoft Account security dashboard from a personal device, navigate to the 'Security' tab, select 'Advanced security options', and click 'Sign me out' to terminate active sessions on all devices.
