Due to a priority shift this request has slipped to the backlog. I hate to bring bad news. I will continue to provide the feature team your feedback and votes.

- Share to Outlook: Share a copy of a channel or chat conversation via email directly from Teams
- Actionable Teams Activity Emails: Teams missed activity emails display the latest replies and allow you to reply directly from Outlook
