Microsoft finishes migrating Hotmail users to Outlook.com@ 2013/05/03
To mark the occasion, Microsoft is launching two significant upgrades. It's adding tighter SkyDrive integration that lets users attach files directly from their SkyDrive accounts, including optimized photo attachments. Those who rely on email aliases will also like that Microsoft has finally let us choose an SMTP server to send messages from non-Outlook addresses without revealing the true source -- we won't have to put up with "on behalf of" tags any longer. Both features are rolling out today.
