Messaging System for businesses, launched by Microsoft

On Wednesday, Microsoft Corporation launched a new messaging system for businesses as a direct rivalry with fast-growing start-up Slack and Facebook Inc’s workplace product.

The new software will be a share of Microsoft office 265 services which is a cloud-based software company that has more than 85 million monthly active commercial users.

Slack, whose customers include CBS Corp, BuzzFeed, universities and the U.S. government, had 4 million day-to-day active users in October.

Slack, San Francisco based company, published a full page ad in New York Times conveying the inclusion of Microsoft terms.

“We’re genuinely excited to have some competition,” Slack said in the ad.

Microsoft said a preview of Teams will be available to Office 365 commercial customers with enterprise or business plans, starting Wednesday.
