    We are happy to share that Electron 10 is rolling out to the public ring now, so you should notice improvements. We expect overall performance of Teams to improve even further with upcoming fixes around the calling and meeting features We will share another update as soon as we are able to.

  2. Reliability issues: crashing, hanging, freezing

    Literally Teams will crash 5 or 6 times a day. Hugely annoying and unproductive.

    Feature teams have been finding unique areas of improvement around crashes/hangs/lock ups of the client, and have been making small improvements through both proactive and reactive findings to help around reliability regressions. If you happen to see any unique issues, please let us know and we will continue to share updates as they become available.

  3. scroll performance - messages are grey boxes before rendering

    scroll lag : scrolling performance (i.e. to previous messages in a chat/channel) is much worse than expected - messages don't render for a noticeable period of time

  5. Poor performance on MacOS

    I can't use teams with out it lagging severely. When I go and look at the processes running, It always looks like the 'helper' is taking up crazy amounts of CPU and it lags out the application to the point of it almost being unusable.

    I've tried closing the application, rebooting, re-installing, checking for updates, etc.. nothing works.

    I'm on macOS Mojave 10.14.2

    Thank you for your feedback. We are continually looking to bring performance boosts to the Mac Client, including improvements with Electron 10 that are releasing. We are also aggressively addressing other areas of performance around the Mac client

  6. High CPU/GPU/Power usage

    For some reason the latest update has Teams using between 8% and 25% CPU idling, doing nothing. There is an issue with this update.

    Thank you for your continued feedback. We are continuously improving the clients to use less memory and RAM.

    The upgrade to Electron 10 has rolled out fully to the public at this point. Telemetry and testing has shown that this is helping to improve memory performance on the client.

    We will continue to work on improvements, and will share more updates as they become available.

    For more details on how Teams currently uses memory, please visit https://docs.microsoft.com/en-us/microsoftteams/teams-memory-usage-perf.

  8. Slow app launch

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

    Application load time is something we are continuously working to improve, and the team is hard at work on fixes. We have validated a recent regression in application launch time that will be fixed in the coming weeks.
