Is there any service besides Outlook to index Hotmail and make it instantly searchable? Gmail does a good job at it but as yet unable to find a similar service for outlook.com.
The easy way to do it is to use an email client. Or you can use an archiving solution such as MailStore Home to allow you to search all of your email accounts in one shot. They have even made it portable so you can run it from a USB stick - no installation required. Best of all, it's free.
