Thank you for your patience with this ask. This is a feature is available on Teams web client now. We are currently testing the functionality of extending drag and drop support of file attachment directly from Outlook to Teams app. We will share an update as soon as one is available.
if you have an existing post that you want to show in a different channel, you can edit the message and cross-post. This will add the top-level post to the different channel, but will not include the full set of replies. We will keep this request in mind as we evolve the cross-posting feature in the future and update if the status changes.
Details on cross posting can be found here: https://support.office.com/article/cross-post-a-channel-conversation-in-teams-9c1252a3-67ef-498e-a7c1-dd7147b3d295.
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
See this post for more information:
This continues to be on our backlog due to prioritization of other work items. We will update when there is more to share.
Thank you for your feedback. The feature team is currently working on introducing pinning to posts and replies in channels. We will share an update as soon as one is available.
