Thank you for your votes and comments on this feature. The team is in the process of finalizing designs for deleting private chat threads. I will update as we have more progress to share.
This is working today in the web client on Edge & Chrome. The team is actively investigating feasibility in the desktop client.
Adding email as a left tab panel remains under review. We are working on adding several Teams and email integrations:
- Share to Teams: Share a copy of an email and any attachments into a chat or channel directly from Outlook
- 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

The ability to use multiple Teams accounts at the same time is supported on iOS & Android today. The feature team is continuing to work on support for multiple accounts on desktop and web clients. We’ll keep you posted as we have more details.
