With its main offices in Tokyo, Japan, Rakuten ranks among the world's top 10 Internet services companies, with more than 9,000 employees in several countries. To determine which product to use, Rakuten compared Google Apps with Microsoft Office 365, a subscription-based offering that unites familiar Microsoft Office applications with the power of Microsoft Exchange Online, SharePoint Online, and Lync Online into one connected, online solution. To support its rapid expansion, Rakuten wanted to improve its messaging environment. After comparing Google Apps and Microsoft Office 365, Rakuten decided to adopt Exchange Online in Office 365. It now enjoys strong security, a lighter IT workload, and an integrated messaging system for both local and overseas personnel.
