It would be good to be able to click on a calendar button on the left hand side to get a view of the Office 365 groups calendar as you would in the calendar app. Good for being able to look and get a glimpse of what is coming up with the group. At the moment I have to go back to the calendar to look at it.

I want to have separate top-level windows for each person I'm chatting with, rather than tabs.

I really like Teams. I do. But the current chat layout is not suited for professional chats. It's way to space consuming. It looks like something imported from MSN with smiley's that take half of the screen. I would say that Slack have nailed it because they focused on the ability keeping a tight window with lots of chat text visible. In Teams the window is full and starts scrolling after like 10 sentences.

We would like to move a project (channel) between groups to keep the information, or be able to sort channels to our liking.

My team has some users on Linux, and one benefit Slack has is a Linux client. Without a Linux client on Microsoft Teams, some orgs may have to turn away in favor of Slack so everyone can participate without keeping a browser open all the time.

Would be nice if we had the ability to archive channels. For example: we created a channel for a specific project. Once the project is complete, we can archive that channel or at least move it out of the primary view. I could see the channel list getting large and clunky quickly with multiple projects many of which are complete.

Also, when a conversation in the channel is complete it should be archived or hidden.

Ability to see who is currently in a channel. Hipchat and Slack have this feature

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

Please integrate more with Planner (hopefully soon with Kanban and timeline visualisation channels for tasks) and/or with sharepoint web parts that do this, so all tasks linked in one place. And Outlook as well (for calendar and emails pertinent to chats and tasks). Until then in effect Teams is yet just another tool to use that is not completely integrated for communication + coordination.

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.

Dragging and dropping attachments directly from the e-mail window without having to first drag them onto the desktop (for instance) and them from there dragging them to the files tab in Teams would make many lives so much easier.

There are a few suggestions to enable drag and dropping, but it seems that it is already working, at least with the desktop client, but making that work directly from an e-mail window would be very nice.

Please bring back the Clippy Sticker Messaging Pack for Teams. It was a really fun sticker pack that brought back the nostalgia of a favorite Microsoft mascot in a new and fun way!

When renaming a Team Channel, the associated Sharepoint folder continues with it's previous name. This could lead to confusion.

Would love to have a Calendar to allow those in the same team to view each other's availability and whereabouts. Would make it a lot easier to create appointments/meetings.

The calendar could be a tab in a channel (so then you could have multiple calendars in one team) or could be an icon on the left app bar, instead of "Meetings" which is helpful to no one.

Could also be helpful to add a way for us to add a SharePoint Team calendar.

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
