Microsoft has phased out or disabled the “Export Mailbox” feature from Outlook.com (OWA) due to its unreliable processing of large mailboxes. So backing up your mailboxes directly from Outlook.com is no longer a viable method. However, you can back up your @Outlook.com, @hotmail.com, @Live.com, @Msn.com, and other Microsoft email services mailboxes in different ways.
