Right now, switching between tabs is painfully slow since tab content is reloaded everytime you visit a tab. (Especially true for integrated web services like Wrike)

Right now it simply loads too slowly, and it has that massive in-your-face splash screen while doing it.

Conversations (chats) in Teams should be able to exported f.ex. to excel.
Should be able to be filtered by Name,Date... to have the possibilty to filter and analyze the content/informations

My goodness, every time you start Teams it's as though it's the first time. Most or all history is gone until it pulls it down from the cloud again. If you want us to use it, make it start in less than 60 seconds.

Browsing chat history is difficult even in case of only few days old messages because these are not loaded on time when scrolling.
I would like the ability to cache chat hostory locally for selected channels and decide how much time of the history I want to be available locally.

How is that the free version Skype screen sharing have no issues, at the same time the paid version (Teams) always have issues, even though the teams screen share is a wrapper on existing skype?

Currently when I open a PDF in MS Teams "PDF File Viewer" I cannot click on the hyperlinks. Instead I have to download the document or open it in SharePoint just to click a link. Such a waste of time!

Interface has a lot of lag and requires massive improvements. I cant quickly scroll through the lists in activity area. Same is many other area particularly when the conversation has lot of messages.

At our company, 100% of its employees telecommute. This makes our preferred method of live communication to be chat. Sometimes we need to copy snippets of a conversation into a work order, and it is SO difficult to copy text from Teams. Sometimes a person's name won't even appear above their text, once pasted, and the information has to be recreated. Please test this for yourself - copy and paste a few lines of a conversation, and please fix this!!!! Thanks!

When I open a tab (a OneNote tab for instance) there is a 2 - 3 seconds delay while it loads.
This even happens everytime I switch tabs, which is extremely annoyng. Maybe you could implement a cache or something to prevent this?

Addign attachments is very slow process. Something minuscule like 50kb sile adding takes 5-10 sec. Lager files naturally longer. It should be instantaneous.

And why I have to wait for the upload at first place before I can send an message. It should be background process.

Looking at UserVoice there are a few requests dealing with network utilization. Microsoft provided guidance on network bandwidth requirements for media traffic with Skype(https://docs.microsoft.com/en-us/skypeforbusiness/plan-your-deployment/network-requirements/network-requirements). This helps provide large enteprise customers guidance during architectural decisions as well as assist with right sizing their current audio/video usage. This is missing for Team and is needed to assist customers sizing their environment correctly as well as assist with future planning. This can help decrease some of the network bandwidth asks as customers will have better guidance on what is expected with Teams over SfB

All work entered needs to ha e feedback for students but this is not much good if the student can't have the chance to act on the feedback and improve or redraft work.
A button to send work back to students or just to allow more files to. We submitted would be great

Running Windows on a Retina MacBook with an external monitor I have the scale of the retina display set to 175% and the external (Main display) to 100%.

Now if the main screen (seemingly only on boot counts) is the external one, the teams interface is so small that it is basically illegible. If the external monitor is disconnected while booting the teams UI is normal on the Retina display, but gigantic on the external one, when connected. Other apps seem to handle this, it would be nice if Teams could, too!

The desktop application hangs up a lot and seems to take very large amount of time for simple things like change the chat context

Teams constantly consumes a small amount of cpu time which blocks my laptop from ever sleeping or hibernating because it is never idle. This is not ideal for many reasons. Obviously the software designed around a polling model which is not generally considered to be a great design pattern. To rephrase this as an idea: Change teams so it works on an event based model rather than constantly polling for updates.

Teams app on win 10 is frustratingly slow to close after clicking red x. Taskbar lights up with new message but shows name of last conversation partner not new one. Opening up to see a new message starts you where you left off instead of new message. Badges on phone app don’t go away if I check on messages using Windows app. Nowhere near as snappy as like, AIM back in the day

Please create a powerBI content pack so that its possible to manage adoption of Teams in organization. Obivous charts are:

most active channel/group
most active user
trend graph for number of channels /teams created over course of time (week/month)
Activity overview (chat, group chat, content sharing)
amount of time spend on meetings organized thru teams

etc
