How to Sign Out of Outlook on Windows 10

Outlook on Windows 10, especially the desktop application, doesn’t feature a straightforward “sign out” button like many web-based email services. To sign out effectively, you need to remove your email account directly from the Outlook application’s settings. This process ensures your emails, calendar, and contacts associated with that account are no longer accessible through the app on your computer. You will navigate to the “File” menu, then “Account Settings,” and choose to remove the specific account you wish to disconnect. This action completely severs the connection between your email and the local application, securing your privacy.

Tutorial – How to Sign Out of Outlook on Windows 10

We are going to walk through the exact steps to remove your email account from the Outlook application on your Windows 10 computer, which is the closest thing to signing out you will find. This process will keep your data private and ensure no one else can access your emails through that app.

Step 1: Open Outlook on your Windows 10 PC.

This is your first move, naturally. Just find the Outlook icon on your desktop, in your Start menu, or on your taskbar, and click it to run the application. Make sure it is the desktop app, not the web version in a browser, which behaves differently.

Step 2: Click on the “File” tab in the top left corner.

Once Outlook is open, look for the word “File” at the very top left of the window. Clicking this opens a new menu that takes you to the “Account Information” screen, where you can manage your settings.

Step 3: Select “Account Settings” from the menu.

On the “Account Information” screen, you will see a button labeled “Account Settings.” Click this button, and a dropdown menu will appear with “Account Settings…” as the first option. Choose this option to open the account management window.

Step 4: In the Account Settings window, choose the “Email” tab.

A new small window will pop up, titled “Account Settings.” This window has several tabs; make sure you are on the “Email” tab, which is usually the default one. This tab lists all the email accounts currently connected to your Outlook application.

Step 5: Select the account you wish to sign out of and click “Remove.”

Carefully review the list of email accounts and click the one you want to disconnect from Outlook. Once it is highlighted, click the “Remove” button, which is typically located above the list of accounts.

Step 6: Confirm the removal when prompted.

Outlook will ask you to confirm that you really want to remove the account. It might warn you that the offline cache for this account will be deleted. Click “Yes” to proceed and finalize the removal.

After you confirm the removal, your chosen email account will be disconnected from the Outlook application on your Windows 10 computer immediately. All associated emails, calendars, and contacts that were stored locally will be deleted from your PC. You will no longer receive new emails for that account through this specific Outlook app, and you will effectively be “signed out.”

Sign Out of Office in Classic Outlook (Without Removing Mail)

Classic Outlook does have one sign-out option, but it signs you out of your Microsoft 365 or Office identity rather than out of a mailbox. Go to File > Office Account and click Sign out under User Information, then confirm. According to Microsoft’s Sign out of Office guide, this disconnects Office apps from services like OneDrive, removes your settings and clears your recent documents list.

Email accounts you added to Outlook keep working after this, so it does not stop someone from reading your mail. If you use Microsoft 365, Office will also ask you to sign back in to stay activated. To remove access to a mailbox, use the Remove steps above.

Sign Out of the New Outlook for Windows

Many Windows 10 PCs now have the new Outlook app, which looks like Outlook on the web and has no File menu. To sign out of an account there:

1. Click the Settings gear in the top-right corner.
2. Choose Accounts > Email accounts.
3. Click Manage next to the account.
4. Click Remove and confirm.

This matches Microsoft’s instructions for the new Outlook. If it is the only account, the app returns to its sign-in screen.

Sign Out of Outlook.com in a Browser

If you read mail at Outlook.com rather than in an app, click your profile picture or initials in the top-right corner and choose Sign out. On a shared or public computer, close every browser window afterward. Microsoft also explains how to sign out of Outlook.com on every device at once from your account security page.

Troubleshooting

Outlook signs me back in automatically

Windows may have saved your credentials. Open Credential Manager from the Start menu, choose Windows Credentials, and remove entries that mention Outlook, Office or MicrosoftOffice. Also check Settings > Accounts > Email & accounts and remove the account there if Windows is using it for other apps.

The Remove button is grayed out

You cannot remove the account that holds Outlook’s default data file while other accounts exist. Set another data file as default under Account Settings > Data Files, or remove the whole profile from Control Panel > Mail > Show Profiles.

I removed the account but the emails are still visible

A local Outlook data file (.pst) may still be attached. Close it by right-clicking it in the folder pane and choosing Close, or remove it under Account Settings > Data Files.

Tips for Signing Out of Outlook on Windows 10

• Understand the “No Sign Out Button”: Remember, the Outlook desktop application on Windows 10 doesn’t have a simple “Sign Out” button like web-based email services. Removing the account is the standard method.
• Backup Important Data: Before removing an account, especially if it is a POP3 account, consider backing up your Outlook data files (.pst) to prevent losing any important emails or contacts.
• Remove Shared Accounts Carefully: If you are removing a shared mailbox or an account used by multiple people, make sure everyone who needs access has it set up elsewhere or understands the removal.
• Consider Webmail for Temporary Access: For quick, temporary access to your email without setting it up on the desktop app, always use the web version of your email service (e.g., Outlook.com) in a browser.
• Uninstall Outlook for Complete Removal: If you want to ensure there is absolutely no trace of your account or Outlook on your system, you can uninstall the entire Microsoft Office suite or just Outlook itself through Windows Settings > Apps> Apps & Features.
• Manage Profiles for Multiple Users: If multiple people use Outlook on the same computer, consider setting up separate Outlook profiles for each user. This helps keep accounts distinct and makes “signing out” easier by switching profiles.

Frequently Asked Questions

Can I just close Outlook to sign out?

No, simply closing the Outlook application does not sign you out. It merely closes the program window. Your account remains configured in the application and will be available again as soon as you reopen Outlook.

What if I don’t want to delete my account, just temporarily sign out?

Classic Outlook has no temporary sign-out for a mailbox. File > Office Account > Sign out only signs you out of Office, not your mail. The best options are to set up a separate Outlook profile for each person, or to use the web version of your email service through a web browser. This keeps your desktop app setup intact.

Will removing my account delete my emails from the actual email server?

Not for most accounts. Removing your account from the Outlook desktop application on Windows 10 only deletes the local copy of your emails and account configuration from that specific computer. Your emails and data will remain safe and sound on your email provider’s servers, accessible via webmail or other devices. The exception is a POP account, which may store messages only on your PC, so export them to a .pst file first if you want to keep them. If Outlook is also on your phone, that app is separate, so follow our steps to sign out of the Outlook app on iPhone as well.

How do I add my account back after removing it?

Adding your account back is straightforward. You would go back to the “File” tab, then “Add Account,” and follow the prompts to re-enter your email address and password. Outlook will usually configure the settings automatically.

Is there a difference between signing out of Outlook and signing out of my Microsoft account on Windows?

Yes, there’s a big difference. Signing out of your Microsoft account on Windows 10 affects your entire Windows login and can sign you out of all Microsoft services linked to that account on the PC. Removing an account from Outlook only affects that specific email account within the Outlook application. They are separate actions with different impacts.
