Application unresponsive while typing messages/switching teams/etc
Recently my colleagues and I noticed that the UI in Teams is getting more and more unresponsive over time and even completely unusable at certain moments.
Cases where this happens:
- Opening a (group) chat and trying to type a message. The application will take up to 10 seconds before the UI becomes responsive.
Even after letting Teams "recover" for some while it's still incredibly difficult to type a message. I can type full sentences before they are visible in the chat area.
- Switching between chats or teams triggers the above behaviour. In addition it freezes the UI completely. …93 votes -
Teams Desktop - Mac - High CPU
Desktop Teams seems to result in very high CPU when having meetings. This includes meetings with presentation and incoming / outgoing video. This makes the rest of my computer and applications very sluggish and slow

Teams desktop memory and CPU leak
Windows 7 with all updates. Desktop Teams 1.2.00.21068 (64-bit) - the latest available for me at this moment. High CPU and memory usage (see attached image). Teams window is not active, no chats and other activity. It happens sometimes, I can't find any pattern. The only way is to kill processes. Closing the app just closes that process with high memory usage.
Installed Memory - 8 GB, Processor - Intel Core i5-2320

Extremely slow lately
The teams app has become extremely slow lately. Everything takes time - starting a new chat, navigating to a channel, opening a tab etc.

Excel freezes during screen-sharing session

TEAMS browser CPU and memory leak
Reporting a memory leak bug in TEAMS running inside a browser.
There is a resource leak or infinite loop condition or something. It will gradually escalate to using 99%+ of the CPU and eventually eat up all the memory too. Closing the Teams tab fixes the problem immediately. I’ve been able to reliably reproduce this in Chrome, Edge, and Firefox (haven’t tried in IE or Safari) across three different Windows 10 devices. I don’t need to do anything beyond login to Teams, and it starts to devour resources.11 votes -
MS Teams for Linux - Sharing screen not working anymore [BUG]
Hello
since I have installed MS Teams latest version (1.3.00.16851), sharing screen is not working anymore.
I can share only a black screen red-bordrered; visible only contextual menu on mouse right click.
I had to downgrade to version 1.3.00.5153 and then sharing screen is restored.10 votes -
Sharing screen problems - Presentation mode not working as intended MTR / SRS
The sharing screen with HDMI is not working as intended.
Static connected devices, such as ClickShare, Wepresent, Airtame, local PC, InstaShow, etc. will appear in sharing automatically when in a meeting call. But this won't "disconnect" or stop when the button to disable sharing is pressed. You have to physically disconnect the HDMI cable.
As for most of our customers, they have a device connected to HDMI at all times. All these MS Teams rooms now become close to useless due to these issues now. Users are frustrated, IT-support cases are growing in huge numbers due to this.
In case…

Submitted Onenote assignments are not locked to editing when viewed in Teams
Once a student submits a Onenote assignment, the page should be locked to editing in the student notebook. When a submitted page is opened by the student with the browser or desktop app (Windows), the page is, in fact, locked and cannot be edited. If, however, the student views the assignment in Teams and then notebook page is opened in Teams, it will display in read-only mode. Then if the student clicks the "Edit Notebook" button the notebook page can be opened and edited in both the browser and the desktop app. It is effectively not locked to the student,…

Virtual Cameras Gone with last update
I use a Sony A7R as my camera so that I can have full control of the images I'm presenting during meetings in Teams. With the last update, MS has taken away all virtual cameras. If I revert back to an earlier version of Teams they work perfectly....but within a short time Teams, auto-updates and the camera goes away. MS seems to take great features away with every update.

We have users in multiple groups in shifts, but doesn't sync schedules across each group
We have users in multiple groups in shifts, but doesn't sync schedules across each group. Can you please look at allowing a user's scheduled to be sync when you are in multiple teams and groups? i.e. we have a separate Leadership Team and Sales Team, but a couple of users are in both. This means we need to manually enter our shifts for each team.

So very laggy
Teams is all but impossible to use on my machine, a MacBook Air. It lags and takes up lots of memory, causing every other app on my computer to run slow as well.

Teams stutters and lags extremely after being open awhile, has to be quit fully and reopened to stop lagging
After having teams open for a few hours, possibly after sending a few stacks of messages, the application starts lagging heaps. For example, it may lag while typing (if I press ENTER to send, it wont register, and registered the next half of the second message in the first message instead), takes 1000 years to load other chats, takes ages to load the next message etc. I have had to open Teams in the hidden icons area of the TaskBar, and QUIT and reopen Teams.

MS Teams constantly crash when sharing screen
Teams crashes on every call and meeting when I try share my screen. If I'm lucky it will be ok for 1 or 2 mins max before crashing.
Other users in my organisation and 3rd party calls often share their screens with me with no issue.
'Old' Skype for business we have, still working fine, but my company is losing this soon.
Microsoft - seems to be a very common compliant - please fix very soon.
