Email groups in Microsoft 365 (often called distribution groups) allow you distribute a single email sent to your organisation to multiple members of staff. This is great when you have a team of staff within the same department or with a common goal as it allows for wider communication within the team and may reduce administrative overhead.

An example of where this may be useful is if you need to distribute changes in a regulation to your accounting team who may be all physically separated. You could have an group named accounts, where all your accounting team are a member and you can send a single email, which all the members of the accounting team would receive.
