If you don’t like outlook.com you can return to Hotmail – for now.
If you’ve tried Outlook.com mail service and don’t like it, you can switch back to the Hotmail interface easily.
On the top right of the Outlook.com page is a ‘gear’ icon, click on that and then choose the Switch to Hotmail option.
Keep in mind that Outlook.com is in beta testing now but eventually will become the default for everyone using the free Microsoft service. Existing Hotmail users will be forced to the Outlook.com interface at some stage, probably in 2013.
