It is annoying to have to click on the “New Messages” button or scroll down manually when new messages arrive. The suggestion here is to keep scrolling down to bottom and to provide a button to jump back to last unread message.

I would like code snippets with highlighting based on code language. And for snippets longer than X lines, a "show more" button (like slack)

The "reply" button is WAY too large under each message. I recommend either making the button just a smaller icon and off to the side of a message, or only showing it on hover.

If there was an Outlook tab integrated on the left, similar to the Meetings tab (which is effectively the Outlook calendar), one could stay in Teams all day and not have to switch out.

Slash commands for just about every type of function are a must have. They are familiar and easy to use without having to touch your mouse, they are UI-agnostic. Admittedly not terribly discoverable – but the UI is even worse, as their is no real option for auto-completion of UI elements, now is there?

Have a possibility to mute a group chat, so no sound or mobile notification should be received fora user that chooses to mute some group chat. Also let me be able to leave it completely if I want to.

Slack has this: get.slack.help/hc/en-us/articles/206870317-..

Allow clickable links on #hashtagged items ... in a channel or group, perform a search within that group.

For DMs and conversations, search all of your conversations

pressing the up arrow when the custor is in the compose box, it will edit the user's last message.

While there's an indication of the user that's actively typing in the Chat area, I'd like to have this in the Teams area as well

Mobile working, Asynchronous working of teams is a common phenomena. Read receipts let us know if the message has been seen, so we know it can be acted on. Critical when large numbers of the team are mainly mobile workers.

IMPROVE actual markdown:

Disable auto-formatting of markdown
*italic* not *bold* or _italic_
Make it the SAME as GITHUB
https://guides.github.com/features/mastering-markdown/
which is closer to DaringFireball
http://daringfireball.net/projects/markdown/

IMPROVE for mobile:
Please add markdown support for Android client.

IMPROVE for other languages:
Currently the code formatting doesn't work for german keyboard users due to the system expecting another character after the `
Due to that, Teams does not recognize the ` and interprets it as any other character.
I think that needs to change.

If a conversation is started in one channel but gains importance to the point where the conversation deserves its own channel. Or a conversation was started in the wrong channel and needs to be moved

Guys, please add pinned items for channels. We often pin important articles/messages/files so that the whole team can see it. Very important!

Would be nice to make it possible to post pictures directly into a Team channel form anywhere (browser, files, etc)

Provide an option to include chat history when you add new person to a group chat

Current when @Tagging someone you have to type @PartOfTheirName then wait for the dialog to pop up, then hit tab or enter click the desired name (Person, Channel, Team). If you fail to use the dialog the @Tag fails to work even if you match the name perfectly.

What we'd like to see is typing @Name or @ChannelName or @TeamName just works even without using the dialog.
