Groups is a feature of Office 365 that provides a shared workspace for collaboration and sharing. The workspace comes with a shared inbox, calendar, library, OneNote notebook, and planning tool.
An Office 365 group is different from a contact group (formerly called a distribution list). A contact group is a set of email addresses. You can use the contact group to send an email message or meeting invitation to all the addresses at once. To create a contact group, see Create a contact group.
Office 365 Groups must be enabled before you can use any of the collaboration tools. If you don't see the ribbon or buttons described below, the feature might not be enabled for you. Talk to your IT department for assistance.
