In past we had reported about first Office 2010 Technical Preview leak but this time we are late to report about next Microsoft Office 2010 leak and this time its Office 2010 Beta 1. The complete build string is Microsoft Office 2010 14.0.4302.1000 Beta 1.

The leaked Microsoft Office 2010 beta 1 is available in both flavor 32-bit as well as 64-bit and is available for download on most popular torrent websites. The leaked Office 2010 Beta 1 seems to be Ultimate SKU as the title says, Microsoft Office Mondo 2010 Technical Preview.

Arstechnica reports that this leaked Office 2010 beta 1 is buggier than previously leaked office 201 0 Technical Build. We recommend you not to use any leaked applications as it may be infected with viruses.

If you don’t get into the Technical Preview, don’t worry; the public preview of Office 2010 is expected to arrive “this coming summer.”
