I'd like to be able to open multiple instances of Teams so that I can have each instance open on a different Team and perhaps another instance open to the Chat. Not being able to do this makes it hard to keep track of where I am when I'm switching tasks.

Don`t show information about who joined or left the team. We are 19 000 users in our organization, big teams generate long lists of this information where we would rather want to see important information. Some teams have now vacated the General channel because of this problem.
Maybe this technical history can be hidden og located in antother place?

When sharing your screen in a Microsoft Teams video conference, the "Presenting..." bar is in the way of accessing items that require hovering over them to display.

Can you please make it possible to move the “Presenting…” toolbar?

For example, if you are sharing your screen to show a remote desktop session and the remote desktop bar is not pinned, it will be very difficult to access that bar because the presenting bar will appear before the remote desktop bar and remain in foreground much longer than the remote desktop bar.

Allow the same functionality present in Teams for non-gcc tenants. Private channels within Teams for GCC.

Add White Board to GCC subscriptions to enable a higher level of meeting and training interaction.

Allow owners to pin a comment in a chat or channel so you can either direct people to another chat or channel. or lock a message. The pin locks the message at a point that is visible to all and doesn't move from the pin space when people scroll through the chat. Example: pin a notice that they are in an old chat and a new chat is on another <channel> or <chat> and this channel will not be monitored on a regular basis. And after a time the chat will be unavailable.

I understand the Search and Filter functions, but am suggesting being able to set key words and get alerts when those words are posted.
The ability to set key words that alert you if mentioned by anyone within any of the channels to which you subscribe.
The ability to set key words in specific channels that may be different than and in addition to the main set of key words.

Ability to see all assignments from all teams at once

TEAMS meetings within a channel does not appear to allow restricting the presenters to a smaller selection. Allowing participants to move through powerpoint slides is very helpful but allowing anyone to "take control" appears to be a particularly bad idea.

Features global administrator to disable the team

We are a global administrator managing 70,000 users.
If there are many users, many teams are abandoned and inactive.

If there are many inactive teams in a tenant, there is a risk of information leakage.
However, deleting a team risks the loss of information or business impact.

One thing the global admin wants to do before deleting a team is to disable it and watch it.

If we didn't plan ahead, or if needs change, we should be able to convert a team into a channel then move it to another team. Rather than have Team A, B, C, and D, it would be nice to have Mgmt Team with Channels A, B, C, D. However, it seems once you've created the separate teams you are stuck with that structure.

I noticed there are limited setting in the channels and we are utilizing a channel page for other team members to post to share thoughts and ideas. However, as the owners of the page or moderators, we would like to review the posts before they are submitted. Is there a feature for this? If not, please add this. This is a feature similar to how Facebook is set up in receiving notifications of posts on a timeline, etc.

It’s frustrating not being able to reply to a specific team message.

Permitir que en un canal privado existan las videoconferencias.

Need for an Admin to be able to rename Team name, OneNote, Planner, O365 Group, OneDrive, E-Mail.. etc . Basically one option for all associated parts of an O365 / Team.
I opened a case with Microsoft Support and the answer was this is not an option and not recommended.

When co-authoring a document, we need to be able to set the track changes to on by user, instead of it being on for all. I cannot format or work on the document when other have turned on track changes as I don't want my formatting in track changes.

Teams don’t work well on Linux platforms specially my team is having Debian, fedora
