Microsoft Teams launches globally today — watch the livestream celebration right here

After a somewhat lengthy preview period, Microsoft is taking the wraps off of its Slack competitor, Microsoft Teams, today. To mark the chat app's global availability, Microsoft is also holding a livestream celebration (opens in new tab) in which Office Corporate Vice President Kirk Koenigsbauer a mystery special guest will talk about what's new with the service, teamwork, and more. That's set to kick off bright and early at 8:30 a.m. PT / 11:30 a.m. ET, and you can tune in below.

Even since launching in preview in November, Microsoft Teams has enjoyed its share of success. It's available in 19 different languages across some 181 markets worldwide, and Microsoft noted in its launch announcement (opens in new tab) that it's already in use by 50,000 organizations worldwide.

Teams itself has morphed with more than 100 new features added ahead of launch, Microsoft says. Those include audio calls on mobile, video calls on Android, and much more. As part of the launch, Microsoft also announced that it has partnered with SAP and Trello to bolster teamwork and analytics.

There are plenty of updates coming down the line, with Microsoft promising regular feature updates. For now, Microsoft Teams is now officially available for Office 365 business users to check out worldwide. And if you have questions about Team, Microsoft says it will be holding an AMA on its Tech Community site (opens in new tab) at 9 a.m. PT / 12 p.m. ET.

  • Yes! This is looking to be a standout product for Microsoft. Let them really give Slack a run for their money. This shows that Microsoft can also create a compelling solution in response to another company's innovation, just like they've (sadly) been on the receiving end of with most of their other innovations.
  • I hope they have made it so you can enable it per user  rather than a global switch!
  • Why Teams rather than Yammer? Aren't these two apps basically the same?
  • Yammer doesn't sound corporate enough.
  • Double post.
  • Yay another Pile Of Garbage (Like Yammer, Sharepoint, etc) that's a Me-Too product from Microsoft. Yawn.
  • Downvote all you want but the truth hurts.  Sharepoint, Yammer, Teams, and even Exchange are steaming piles of garbage.
  • have to agree yammer was rubbish
  • New patch Tuesday update arrived. 14393.953
  • This was already available only to business so this is silly. Why is it not rolling out for personal? How does that compete with slack? I can't use nothing but slack so it's a fail until the pump it out.
  • lets hope teams gets released to everyone not just business
  • All the more confusing with countless similar apps out there. Maybe 50.000 businesses out there using it, but have heard little about fusing social messaging in business. This apps only seems to saturate an already fragmented market. I know no business using this app.
  • Probably cause of the 365 only Web interface. My company is always 5 years behind or more. But that's a lot of large companies especially ones with important information that can't afford breaches and can't afford to upgrade to the latest every time it comes out.
  • The app is a good idea but execution is really terrible. Why is this not a Windows Store app using Windows 10 main features? And why is the UI inconsistent with every other software that Microsoft has built? Also the webcast was boring and sometimes unprofessional. I'm not sold.
  • Maybe so it can be set to start when a user logs into Windows right from the the installation. Yes, you can make UWP apps start with Windows but it's currently a manual process. Of course, MS' solution to that should be to enable this with UWP apps, not to make Teams a non-UWP app, but maybe that's still a part of why.
  • Why this application is not in the store? Why not a UWP​?
    Microsoft need to show the way...    
  • Office 365 only as far as I understand. I would like to see a standalone program or integration to SharePoint even?
  • Looks very powerful, if not overwhelming, but where is the implementation for the heralded Microsoft dual use strategy for business and personal?
