Learn about Office 365 Groups

Getting things done at work or school means sharing information and collaborating with others. The folks you collaborate with might be in the next room, across town, or in a different time zone, but with an internet connection and common set of tools, you can get your project done from wherever you call home.

Office 365 Groups is a feature developed with collaboration in mind. It works with the Office 365 apps you use already so you can collaborate with your teammates when writing documents, creating spreadsheets, working on project plans, scheduling meetings, or sending email.

What's the difference between an Office 365 group and a distribution list?

A distribution list is a set of email addresses. You can use the distribution list to send an email message or meeting invitation to all the addresses at once. An Office 365 group includes a distribution list but also includes a shared:

  • Inbox for group email communication

  • Calendar for scheduling group meetings and events

  • Library for storing and working on group files and folders

  • OneNote notebook for taking project and meeting notes

  • Planning tool for organizing and assigning tasks and getting updates on project progress

When you join a group, your email address is automatically added to the distribution list and you gain access to all group information. You don't have to wait to see group email or view a shared document. You join, you have access to everything, from everywhere: in the cloud, on the desktop, or on a mobile device.
