Microsoft, Windows Live, Live, Education, Windows Live @ Edu
Windows Live @ Edu is a hosted email service available free of charge to colleges and universities, which is hosted on the Windows Live Hotmail platform. It allows establishments to choose their own email domain name (for example, students.oxford.ac.uk) and use that for all email provision for their students. The back-end is linked to the university's Active Directory, so that users are actively provisioned. It gives students a 2GB mailbox and unlike Hotmail, is advertising free. There are over 20 universities or FE colleges now using this system in the UK.
Although the mail service is free, there is a partner revenue opportunity from this service - the integration and configuration services from the mail service to the institution's Active Directory (using Identity Lifecycle Management 2007)
