How to create dynamic distribution groups in Exchange Online ?

What is a distribution group in Microsoft 365?

A distribution group in Office 365 is a group of users that you can use to send e-mails to a group of people without having to select each person individually. This can be useful if you regularly send e-mails to the same group of people, such as a project group or a team.

With dynamic distribution groups, you can automatically add all IT employees to one group based on 'department of ICT', for example. Useful for delegating group management in the organization. So that this responsibility no longer lies with IT.
