Microsoft Teams—the chat-based workspace in Office 365: Introduction & Frequently Asked Questions

Technical Level : Basic


At Microsoft, we are deeply committed to the mission of helping people and organizations achieve more—and reinventing productivity for the cloud and mobile world is core to our ambition. We built Microsoft Teams because we see both tremendous opportunity and tremendous change in how people and teams get work done. Teams are now more agile and organizational structures more flat to keep communications and information flowing. With Microsoft Teams, we aspire to create a more open, digital environment that makes work visible, integrated and accessible—across the team—so everyone can stay in the know.

With more than 85 million active users, Office 365 empowers individuals, teams and entire organizations with the broadest and deepest toolkit for collaboration. Office 365 is designed to meet the unique workstyle of every group with purpose-built, integrated applications: Outlook for enterprise-grade email; SharePoint for intelligent content management; Yammer for networking across the organization; Skype for Business as the backbone for enterprise voice and video; and now, Microsoft Teams, the new chat-based workspace in Office 365.

After enabling Teams, how do you actually get to the app? It's not available from my "View All Apps" screen, so how do I get to it?
How long is chat history stored for? 
Same issue here. What am I missing?

Hi Matthew,

To get the most recent desktop versions of Microsoft Teams, administrators and users should download from

For mobile apps, you should go to the relevant mobile store for Google Play, Apple App Store, and Microsoft Store.

Your desktop app will automatically update (so you don’t have to). If you want, you can still check for available updates by clicking Settings and then Check for updates.

Your web app will always be up-to-date.

        I have enabled the service and downloaded the app, but how come I don't see a tile for it in my online portal screen?

Hi Robert,

Microsoft Teams retains all messages.

It retains deleted messages for at least 7 days and at most 30 days before messages are permanently deleted.

However, there is no support yet for retaining edit and deletion logs for messages.

Thanks Mário, my issue was that there was no link to anywhere that I could find, so I didn't even know how to get to the web app. The web app is all that I needed. Thanks.
Will Microsoft Teams be available for education licenses anytime soon?
Can I import Slack JSON files into Teams to retain chat history? If so, what are the steps?

The desktop app does not work for my version of OSX (10.9.5). The online page does not load in Chrome on OSX. It simply refreshes until the browser crashes.

I'm attempting to use the web version here
