Thanks for your patience! We’ve begun to rollout a feature for StaffHub messaging to share the same backend as Teams. We plan to hit 100% in the next few months, and will keep you all updated.

Thanks for your comment.
This feature is in the process of being rolled out over the next couple of months. When it is, you’ll be able to toggle on the ability to turn on announcements and be surfaced an alias that will reach your entire tenant as well as whitelist people who can mail to this alias.
Please keep an eye out for the O365 Message Portal for when this feature is released! We’re excited for your feedback. Thanks.
