Just getting started? Here's information about getting started on Microsoft Teams for iOS, Android, and Windows Phone.

Microsoft Teams is a messaging app for teams where all conversations, meetings, files, and notes can be accessed by everyone on the team. It's a place for collaboration and work to happen in the open.

Here's why you should use it:

  • It makes communicating privately one-on-one or with groups a snap.

  • Collaboration happens in real time.

  • Everything your team cares about (all your files, docs, contact info, and more) is in one place.

To download the Teams mobile app, follow the link on our download page. Or download it from the iOS App Store, Google Play Store, or Microsoft Store.

From your desktop, you can find the Teams web app at Teams works with Internet Explorer 11, Microsoft Edge, the latest version of Chrome, and the latest version of Firefox.

To use Teams, you need an Office 365 account with a Business or Enterprise Office 365 license plan. For more information, see How do I get access to Microsoft Teams?

You can’t use the Teams web app on your mobile device, but you can download the mobile app from your favorite app store, if you haven’t already.

All the contacts from your organization are already part of Teams.

Open your app and send someone in your organization a message or add them to a team. They'll automatically get an email invite and a notification.

Microsoft Teams uses single sign-on through Active Directory on your mobile device. That means that you sign in once for Teams and your other Office 365 apps and you won't need to re-enter your credentials when you launch Teams or your Office 365 apps from the same device.

If your organization has multi-factor authentication set up, then there can be an additional step and level of security associated with signing in. For example, after you enter your credentials, you might be asked to verify your identity via a phone call by providing a unique code, your thumbprint, or a PIN.

If you're having trouble signing in, see Why am I having trouble signing in to Microsoft Teams?

Our mobile apps automatically sync every time you open or use them. You can also pull down to refresh your messages.

To access your notification settings, do one of the following:

On Android and iOS, tap More More button > Settings > Notifications.

On Windows Phone, tap More More button > Notifications.

If you're @mentioned, it means someone wants to include you in a conversation or get your attention.

If you type @ before someone’s name, they’ll be @mentioned and notified.

Don’t worry, no one else will receive a notification. They will be able to see that you @mentioned someone, though.

You can access someone's contact card from their profile picture.


In a chat or channel, tap someone's profile picture to see their contact card. In a group chat, tap More options More options button in the header for the chat details. From there, tap the person's profile picture.


In a channel, tap someone's profile picture to see their contact card. From a chat, tap the name or names in header for the chat details. From there, tap the person's profile picture.

Windows Phone

In a channel, tap someone's profile picture to see their contact card. From a chat, tap the conversation header to see the participants.

There’s no way to remove someone from a conversation or group chat once they’re in it, but you can always start a new conversation with a different group of people.

For release notes, go to this desktop article: Release notes for Microsoft Teams.

You'll be able to sign in later with the same account or different credentials.
