M365 Changelog:(Updated) Microsoft Teams: Start a Teams Chat with Distribution Groups, Mail-Enabled Security Groups, and O365 Groups

Rabia Noureen


MC408435 – Updated November 29, 2022: Microsoft has updated the content below with additional information. Thank you for your patience.

You will now be able to start a Teams Chat with Distribution Groups, Mail-enabled Security Groups, and O365 Groups. This feature will respect the limits on members in a group chat, currently set to 250 members.

Organizations rely on Distribution Lists (DLs) as a tool to create groups of users that mirror organizational knowledge and workflows. Bringing this awareness to target audiences for specific content will enhance the core Teams experience. Allowing our customers to leverage DLs can increase workflow efficiency and bridge the gap between legacy knowledge of organization structure and a new Teams structure.
