The Mail app is one of the many apps offered with Windows 10. The official Mail app was first introduced with Windows 8 and the same has been dramatically improved in Windows 10 with new features and options.
The official Mail in Windows 10 is definitely one of the better email apps out there for Windows operating system. Although, it’s not as superior as Outlook or some other third-party desktop clients around, the app offers most of the features that you expect to see in a good email client.
If you have added multiple email accounts to Mail app, you likely want to remove or sign out of an account at some point of time for some reason. For instance, if you had added Gmail account to Windows 10 Mail, you might want to sign out of your Gmail account before allowing others to access your PC.
Luckily, you can sign out of your email accounts added to the Mail app with ease in Windows 10. However, it’s not possible to sign out of the Microsoft account that you have been using to sign in to Windows 10. In other words, this applies to only users who have been using a Microsoft account to sign in to Windows 10.
This is because, when you begin using a Microsoft account to sign in to Windows 10, the same Microsoft account is automatically added to the Mail app, and you can’t sign out of this account or remove the email account without switching your Microsoft account to local account.
Steps how to sign out of an email account in Windows 10 Mail
Step 1: Launch the Mail app.
Step 2: Click or tap the Settings icon to reveal the Settings pane.
Step 3: Click or tap Manage Accounts to view all email accounts that have been added to the Mail app.
Step 4: Click or tap on the email account that you want to remove or that you want to sign out of. This will open Account settings dialog.
Step 5: Finally, click or tap Delete account (Remove this account from your device).
Step 6: Click or tap Delete button when you see the following confirmation dialog to sign out of the account and remove the email account from the Mail app as well as your device.
And if you’re not getting Delete account option, it’s because you’re using that Microsoft account to sign in to Windows 10. To sign out of it, as mentioned earlier in this post, you need to migrate your Microsoft account to local account first, and then follow above given instructions.
