Tata Steel is migrating its two existing European email systems to a new cloud-computing based platform based on the Microsoft Office 365 productivity suite.
The project is one of the first large-scale enterprise implementations of Office 365 in Europe. Tata, the second-largest steel producer on the continent with primary operations in the UK and Holland, is aiming to cut costs with the project and improve collaboration across its workforce.
Microsoft and outsourcer Capgemini will work on the migration and on integrating the new productivity suite with other back-office and production systems.
Tata will also be using Microsoft Exchange Online, unified communications platform Microsoft Lync Online, and online archiving and encryption as part of the project.
Shreekant Mokashi, chief group information services at Tata Steel, said: "This move to an enterprise-ready cloud communications platform will be a significant contributor to our plans to reduce our overall IT operating costs."
The Microsoft Office 365 win will be seen as a significant step towards Microsoft catching up with the established Google Apps offering in the cloud productivity suite marketplace. Associated Newspapers also recently signed up to Office 365.
Meanwhile, Google Apps users include ITV, Rentokil Initial and Jaguar Land Rover.
