Dixons Retail is deploying the cloud-based Office 365 desktop productivity suite across the UK, Ireland, the Czech Republic and Hong Kong to support 20,000 users.
The electrical retailer is using the cloud-based Office versions of Exchange, SharePoint and Lync to aid staff collaboration and support flexible working and save money.
The retailer says it is moving towards a more mobile strategy, which will mean that colleagues do not have to be at a fixed point to receive information or work collaboratively.
Currently not all Dixons staff hold email accounts, while multiple email systems, including Lotus Notes, exist across the organisation.
Through Office 365 Dixons will deploy a central email system across all locations, with the aim of improving and streamlining communication across the business, making it easier to contact individuals and circulate messages en-masse throughout the organisation.
Microsoft SharePoint will form a central communication platform as well as a repository for Dixons staff to store and access documents, allowing them to work collaboratively, reduce storage and ensuring that there is a "single version of the truth" as opposed to multiple versions of the same document, said Dixons.
Matt Horwood, IT director at Dixons Retail plc, said, “The implementation of Office 365 will significantly improve the way we work together within the organisation. But more importantly, improve the way that we interact with our customers."
Horwood said, "It is crucial that we continue to be progressive in how we deliver service. Office 365 will not only increase the amount of time that our staff can spend on the shop floor, but also arm them with the right information to serve customers effectively."
For the roll-out a pilot project is taking place before xmas, with a full roll-out to 20,000 staff expected to be completed by March 2013.
Earlier this year Apple hired John Browett, chief executive of Dixons Retail, to take the reins of its own retail arm, but was shown let go by the California-based tech giant just a few months later.
