Learn How to Sign Out of Outlook Email

Understanding Outlook Email Sign Out Basics

Signing out of Outlook email is a straightforward process that involves ending your current session and closing your account access from a device. Whether you use Outlook.com, Outlook.office.com, or the Outlook desktop application, the sign-out procedure works to protect your account security and privacy. When you sign out, your email account becomes inaccessible from that specific device until you sign back in with your password.

Many people use Outlook for personal email communication, business correspondence, or both. Understanding how to properly sign out is important because it prevents unauthorized access to your messages, contacts, and calendar information. According to Microsoft's security guidelines, logging out when you finish using email on shared or public computers reduces the risk of someone else viewing your private communications.

There are different reasons why you might need to sign out. You may be finishing work on a shared computer at an office, library, or internet cafe. You might be switching to a different account. Perhaps you're troubleshooting a connection issue or preparing to lend your device to someone else. Some people sign out regularly as part of their security routine, while others do it only occasionally.

The sign-out process differs slightly depending on whether you're using Outlook on the web through a browser, the Outlook desktop application for Windows or Mac, or the Outlook mobile app on a smartphone or tablet. This guide covers the various methods so you can sign out from whichever platform you use.

Practical Takeaway: Signing out of Outlook is a quick action that takes seconds to complete. Knowing how to do this correctly on your specific device helps protect your account and ensures you're using Outlook securely.

How to Sign Out of Outlook on the Web

Outlook on the web is the version you access through an internet browser like Chrome, Edge, Firefox, or Safari. This is the most common way people check email when they're away from their desk or using multiple devices. To sign out from Outlook on the web, look for your profile picture or initials in the upper right corner of the screen. This icon appears as a small circle or square, usually next to any notification bells or settings options.

Click on your profile picture or initials to open a dropdown menu. This menu contains several options related to your account. You will see text that says "Sign out" or "Log out" in the menu. Click on this option. Your Outlook session will end immediately, and you will be returned to the Outlook login page. You can then close the browser window or tab.

Sometimes the profile menu appears slightly different depending on which version of Outlook you're using or recent updates from Microsoft. If you don't see a profile picture in the upper right corner, look for a settings icon (usually shaped like a gear) and click that instead. From the settings menu, you should find an option for account-related actions, including sign out.

If you're on a shared computer, you may also want to clear your browser's cache and cookies for added security. This removes stored login information that could potentially be used by another person. Most browsers have a history or settings menu where you can select "Clear browsing data" or "Clear cache." This step is optional for personal devices but recommended for computers used by multiple people.

Practical Takeaway: On Outlook.com or Outlook.office.com in your web browser, click your profile picture in the upper right corner and select sign out. This takes about 5 seconds and completes your session.

Signing Out of the Outlook Desktop Application

The Outlook desktop application is software installed directly on your computer. This version of Outlook is commonly used by people who work in offices or who want email access without opening a web browser. It's available for both Windows and Mac computers and often comes as part of Microsoft Office subscriptions. Signing out of the desktop application requires a different process than signing out on the web.

For Windows, open the Outlook application and look at the top menu bar. Click on "File" in the upper left corner. A menu will expand showing various options. Scroll down until you find "Account Settings" or simply "Exit." You can also look for an option that says "Sign out" or "Remove Account" depending on your Outlook version. Some versions of Outlook display these options directly in the File menu, while others may require you to navigate through Account Settings first. If you select "Account Settings," a window opens where you can see your connected email accounts and remove or sign out from them.

For Mac, the process is similar. Click the "Outlook" menu in the top left of your screen (next to the Apple logo). Look for an option like "Sign Out" or navigate to preferences to manage your account. Mac versions of Outlook sometimes handle sign-out differently, so you may need to locate the settings or preferences area and find account management options there.

After signing out of the desktop application, you may see a login screen the next time you open Outlook. This login screen asks for your email address and password before you can access your messages again. Make sure you remember your password before signing out, or have it written down in a secure location.

Practical Takeaway: In the Outlook desktop application, go to File menu and look for Account Settings, Sign Out, or Exit options. The exact wording varies by version, but these menu options let you end your session.

Signing Out of Outlook on Mobile Devices

Many people check Outlook email on smartphones and tablets using the official Outlook app or through the phone's built-in email client. Mobile devices have different security considerations than desktop computers since you often carry them with you and may set them down in various locations. Signing out of Outlook on mobile works differently on iPhone/iPad versus Android devices, though the basic concept is the same.

On iPhone or iPad using the Outlook app, open the application and look for a menu icon. This is typically three horizontal lines (called a hamburger menu) or a settings icon in the corner of the screen. Tap this icon to access the menu. Look for options related to your account or settings. Scroll through the menu until you find an option that says "Sign Out," "Log Out," "Remove Account," or "Settings." Some versions show this directly in the main menu, while others require you to go into a settings area first. When you find the sign-out option, tap it and confirm your choice if prompted.

On Android devices, the process is similar. Open the Outlook app and tap the menu icon (usually three lines or dots). Navigate to settings or account information. You should find an option to remove the account or sign out. Tap this option and follow any confirmation prompts. After signing out, the app may ask you to sign back in the next time you use it.

An important note for mobile devices: if you've allowed the Outlook app to store your password for convenience, signing out usually removes this stored password. This means you'll need to enter your password again when you sign back in. This added security step prevents someone else from simply opening the app and accessing your account if they borrow your phone.

Practical Takeaway: On mobile Outlook apps, open the menu (usually three lines or dots), find account or settings options, and select sign out. This protects your email if your phone is lost or borrowed.

What Happens After You Sign Out

Understanding what happens after you sign out helps you know what to expect and whether you need to take additional steps. When you sign out of Outlook, your account access from that specific device ends immediately. Your email account itself remains active with Microsoft—signing out doesn't delete your account or any of your messages. Your emails, contacts, calendar entries, and files remain stored on Microsoft's servers.

If you were accessing Outlook through a web browser, that browser tab or window no longer has access to your account. The next time someone visits Outlook.com or Outlook.office.com on that browser, they will see the login page rather than your inbox. If another user shares the same computer and has their own account, they can sign in with their own credentials without affecting your account.

For desktop applications, signing out removes the account from that installation of Outlook. The application will ask for login credentials the next time it opens. You can sign back in with your email address and password, or you can set up a different account on that computer. Your emails don't disappear—they remain on Microsoft's servers and you can access them again once you sign back in.

On mobile devices, signing out of the
