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

MC408435 – Updated September 26, 2022: Microsoft has updated the rollout timeline below. 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. 

This message is associated with Microsoft 365 Roadmap ID 62354

When this will happen:

Microsoft will begin rollout in early November (previously late September) and expect to complete rollout by late November (previously late October).

How this will affect your organization:

With this update, users will now be able to select Distribution Lists as an audience to begin a chat within Teams.
