Microsoft confirmed the acquisition of the office mobile app LiveLoop for an undisclosed amount on Friday.

"We are excited to welcome the talented team from LiveLoop to help build great collaboration across Office applications, part of our strategy and vision to reinvent productivity," Microsoft said in a statement.

LiveLoop is an online service that allows multiple users to collaborate their work in PowerPoint presentations and other documents simultaneously. Users can upload a slide then convert it to a URL that can be shared with other users.

The startup will be officially closed in less than a month based on the site's notice.

"LiveLoop will be shutting down permanently on April 24th, 2015. New user registration and presentation upload have been disabled," the notice wrote.

"Existing LiveLoop users: if you have any data you would like to retrieve from LiveLoop, please do so before April 24th. On April 24th, all presentations and user data will be permanently deleted."

Although the software giant didn't elaborate on its plan about the San Francisco-based startup but, the technology of the plug-in will be a good match for the meeting-and-collaboration-specific software and services that Microsoft is installing on its new Surface Hub video conferencing system, according to ZDNet.

Microsoft has been buying small startups since last year. Prior to LiveLoop, the company bought mobile email app Acompli in December and integrated it on the Outlook for iOS released last January.
