Outlook.com data is not stored on your computer or backed up by Microsoft.
If your data is important it is prudent to back it up, especially if it is in the cloud and not under your control.
This Wiki will show you how to have peace of mind knowing that you are in control of your data.
To back up your email data you must configure your account on a Mail Client.
(With the coming changes to Windows Live Mail you may want to use this email client instead.
It is not from Microsoft but is very similar to Windows Live Mail and it will continue to work to sync all you mail, calendar, and contacts.
It is called emclient and it is available here. http://www.emclient.com/
Using Windows Live Mail.
Follow the steps below to do this:
Download Windows Essentials,.
It comes with Windows Live Mail, Family Safety, Writer, Outlook Connector pack, Microsoft OneDrive.
When you download Windows Essentials, you can choose custom install to install only Windows Live Mail depending on your preference.
Once Windows Live Mail is installed and configured, just sign in to your account and wait for the program to download your emails.
For more information about configuring your account refer to
How do I add an account to Windows Live Mail
When finished downloading you should have a copy on your Hard Drive that is synced with the Outlook.com server.
If you want to save an additional copy in case something happens to your Windows Live Mail you can export both your emails and your account by doing ALT + "F" and exporting both to a different location of your choice.
