Microsoft is improving its online application services and opening them up to SMEs, who can now test them prior to the full subscription-based service being launched later this year. 

The software giant last year launched a similar service to companies with 5 00 employees or more.
The applications include e-mail, calendars and video conferencing which will be hosted and managed on Microsoft's servers.
The service will appeal to companies that don't have their own internal IT systems.
