One of our clients asked about this so I thought I would share what I found out! :)
Teams and groups
In Microsoft Graph, Microsoft Teams is represented by a group resource. Both Microsoft Teams and Office 365 groups address the various needs of group collaboration. Almost all the group-based features apply to Microsoft Teams and Office 365 groups, such as group calendar, files, notes, photo, plans, and so on. The main difference between a team and an Office 365 group is the mode of communication between members. Team members communicate by persistent chat in the context of a specific team. Office 365 group members communicate by group conversations, which are email conversations that occur in the context of a group in Outlook.
The following are the differences at the API level between teams and groups:
- Persistent chat is available only to Microsoft Teams. This feature is hierarchically represented by the channel, chatThread, and chatMessage resources.
- Group conversations are available only to Office 365 groups. This feature is hierarchically represented by the conversation, conversationThread, and post resources.
- The List joined teams method applies only to Microsoft Teams.
- Calling and online meeting APIs apply only to Microsoft Teams.
- See also the known issues for these APIs.
Note: If you use the groups API in a Microsoft Teams app rather than in a standalone app - for example as part of a tab or bot running in Microsoft Teams - follow the guidance in the article Using Microsoft Graph in your Microsoft Teams pages.
It looks like Teams wants to decrease your amount of emails! Not a bad thing.... Here's more info on Teams on our website
