Google removed another key barrier to enterprise adoption of Google Apps with “Google Apps Sync for Microsoft Outlook” that lets Web-based programs by the California Internet colossus work with its rival's email, contacts, and calendars. The move comes in the wake of Google enabling people to use its Gmail web-based email service offline and making software interoperable with Blackberry smart phones popular with business users. Google Apps Sync for Outlook is included in Premier online application packages available for 50 dollars per year per business user. It is free in online services that Google provides for education or nonprofit groups.
