I always share Screen instead of Excel app/file.  I've had to quit and re-open Excel spreadsheets too many times during screen-sharing sessions.

When you UNCHECK the setting "On close, keep the application open" it appears the Teams.exe process does not properly exit. The application disappears, but the tray icon is still present.

The core of the issue is when you click the Teams icon on the taskbar again to open the application it doesn't open. The only way to get the application to open is to right-click on the tray icon and select quit.

I have confirmed the behavior is present on several different PCs.

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.

Teams is draining my Mac battery. I have a new computer this year. Never an issue with any other program. I am using the cord it came with. After a 45 minute Teams meeting I am down from 100% to 77%. For comparison, a one hour Zoom meeting the battery went from 100% to 99%. This is completely unacceptable. I spend half of my day on video calls. Please fix it!

Keeps changing status to 'away' when I'm actively using my computer, and won't let me change back to available.

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.

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.

Hi, when you record a meeting you cannot delete it from the chat. It is automatically deleted after 21 days but this is not enough.

The problem is that even if all students agree to be recorded and something happens during an online class and a student does not agree anymore for the recording to be available - the teacher cannot remove it.

best,
Lara

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.

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.

When having a private channel created, you can't change it to public.

Ms Teams is eating too much memory and cpu cycles

please focus on performance before adding features. On lower end and mid range devices the expericence is horrible. lots of our students complaint over this problem. on the same low end devices zoom works fine.

Just tried using Teams for a remote meeting for sharing screens. Complete failure and nothing works. Screen share invites not sent or received by anyone in the chat. Is this a known issue?

Inefficient memory usage by Teams or Technology used by Teams renders it very bad product which affects workability of the user. This can be particularly seen hampering when you are on Teams Call (Even audio) and then try to do screen share & then work on an application/web page browsing etc on what your are demo'ing. This show pretty bad image of the Application. We need to get rid of the same.

MS-TEAMS users cannot upload/update Profile pictures. USELESS ERROR MESSAGE: "There was a problem with saving the photo. Please try again." Have tried updating profile image on Outlook 2016. Have tried updating profile image in Office 365. Nothing works. It's hopeless -- and so typical of Microsoft that such an unaddressed error should occur. NOT good enough!!
