Microsoft has opened the tap on its cloud-based Office 365 and is now offering the service as a public beta for anyone to try out.

Available in 38 countries and in 17 languages, the new beta follows several months of limited testing among a couple thousand businesses that were able to kick the tires on the service. After the public beta, Office 365 will officially launch later this year.

Unveiled last October, Office 365 is Microsoft's attempt to offer businesses a cloud-based alternative to some of its traditional desktop and server products. The service combines Office Web Apps with hosted versions of Exchange and SharePoint as well as Microsoft's Lync product, which provides the online communication and collaboration piece.
