A teams site is a group of people gathered to get something big done in your organization. Sometimes it’s your whole organization.

Teams and channels menu

Teams are made up of channels, which are the conversations you have with your teammates. Each channel is dedicated to a specific topic, department, or project.


For example, the Mark 8 Project team has channels for:

  • General
  • Design
  • Digital Assets Web
  • Go to Market Plan
  • Research and Development 

All the conversations, meetings, files, and apps in the Design channel have to do with design, and everything in this channel is visible to everyone on the Mark 8 Project team.

Channels are where the work actually gets done—where text, audio, and video conversations open to the whole team happen, where files are shared, and where apps are added.

While channel conversations (posts) are public, chats are just between you and someone else (or a group of people). Think of them like instant messages in Skype for Business or other messaging apps.


  • Chat conversations are stored for 7 days.
  • Channel conversations / posts are stored indefinitely, for now.
