Reliability issues: crashing, hanging, freezing
Literally Teams will crash 5 or 6 times a day. Hugely annoying and unproductive.

Same problem in our company. I contacted the Microsoft support team and after 2 weeks checking logs they gave me this page's link and asked me to write a comment here to give them a feedback. They just said SORRY and I don't understand what kind of support is this. We need this issue be resolved not just SORRY

Same problem, very annoying.
Teams hangs Windows and I then need to reboot. It can happen 3 or 4 times a day.
It seems it only happens when someone shares a screen, otherwize fine.On my PC is the only application doing this, my PC is a PC for work with nothing fancy on it.
Besides it is a Surface Book (Microsoft).
I tried to reinstall, but did not improve anything.
Been like that for many months, no improvement and I am totally fed-up.
The sad thing is that colleagues with Mac laptops seems having no problems with Teams!!!!As an example, just on the 25 Feb 2021, I had to reboot 3 times my PC because of Teams.
I now started using Teams on my Android smartphone (that is very stable) and ignore my PC.Question: why adding more and more functionalities and not fixing this blocking bug? Nonsense.
Does anyone from Microsoft watch this space?

I'd recommend to use Teams Web until Microsoft can resolve the crashes, and Logs can be gathered from right-clicking the Teams Icon and choosing "Get Logs"; that's what I've been advising users at our company.
In the meantime we're still not sure on a clear solution.. but here's a log file that may help Microsoft and/or us users (my colleague had Teams crash yesterday 17th Feb, around 16:00, when attempting to join a meeting.
Something about being unable to load the Sharing Indicator, or Commands that are Undefined?
If anyone has any ideas that would be great, thanks.

Same story here,
As a precaution we have to reboot our systems before entering a meeting like others suggested here.
And DO expect Teams to crash during a meeting! Especially if it is a long one or there are more meetings in one day...When teams crashes it normally crashes repeatingly several times often taking other programs with it. The only way to fix that is to reboot your system. See some (Dutch) screenshots I added.
For people asking how to stop Teams from (automagically) starting in your taskbar: You can turn that behavior off by right-clicking on that icon, then selecting settings in the appearing menu.
Note that the appearing settings-menu is different from the others (of course) Microsoft and other companies seem to find it modern/handy to have as many setting menus as possible for the same program instead of a single one...
Follow the numbered green arrows and line the combined screenshot added here. -

I have the same issue on newest Surface Pro 7 with I7 processor.
Teams, Outlook, chrome, spotify, nothing else. Having random hangs for 3-10 seconds when tryting to respond to someone on the chatbox. Input frozen. I type the message and it appears after the freeze. So strangealso - newest windows, newest drivers...

we use microsoft teams for complete business communication. And we do a lot video calls during pandemic time. We often have to share the screen. And I often have time gaps, frozen picture for up to a minute.
It is really horrable to do video calls with customers. and it is during the day. In the morning hours (Berlin timezone) it is fine, but at arround 10 it gets worse and worse. and the frequenzy of frozen picture and lost connections and out of hearing the others is rising up to every 1 - 2 minute. And after 6 pm it gets better again.
I tried it with put off all other devices from WiFi, but no chance to make it better. And it is only with teams on my laptop. If I use it via mobile phone in mobile network it works smooth. -

During Teams meetings if the producer uses the spotlight feature to focus on the main speaker we get multiple people complaining that the video freezes.

Absolutely pathetic lack of progress on this. Instead of closing of the root issue (https://microsoftteams.uservoice.com/forums/555103-public/suggestions/17219609-teams-uses-600mb-and-is-super-slow) to try and get it off the "Top ideas" list, please put in the work to address the MANY MANY issues with Teams' performance on every platform. It has been YEARS.

We experience the same trouble at work.
If you join a meeting; reboot your PC first. If you have or are joining a meeting all day long, do expect to reboot your PC somewhere during the day.Strangely enough Teams crashing seems to occur mostly around one'o clock central European meantime. This could be my personal PC, but I never plan any regular actions, like (Windows) update or a regular virus scan at that time.
When Teams crashes, it usually keeps restarting a couple of times and I noticed it takes a couple of other programs like Microsoft's default apps (Edge browser, start menu (explorer) et cetera) and non MS programs like Mozilla's Firefox (Tab-pages) and Google Chrome with it.
When I report the errors to the ICT-crew at my company the default response is: Well the in-program-inquiry reports don't show any real bad results. So it must be your PC...
When I argue that a crashed program won't give me an in-program-inquiry I'm blown off by them like I'm silly: No, it really is YOUR PC!
Matter of fact; the program NEVER asks for any experience RUNNING the program itself, it ONLY asks for the audio- and video-quality which are nice if it runs. And you have enough band-with...My conclusion? Frustratingly buggy! The only reason I'm using it is that I have to use it by company rule...

It crashes because of enormous resources consumption - especially memory.

Our standard advice to our staff is to reboot their machines (PCs or Macs) before joining a Teams meeting. Otherwise we get frozen people, crashing machines, inability to share screens etc. What kind of app requires a reboot of the machine in order to run reliably? Please, MS, rewrite the Windows version using a light-weight technology like UWP.

It probably has to do with the large CPU usage on my computer, but this is the end result.

Teams App crashes every time I try to share my screen with one other person on a direct call to another user on Teams. If I create an actual Teams meeting with the Meet Now button, and we both join that call, then I can share my screen without crashing. If I use Teams in Microsoft Edge, then I do not have a problem sharing my screen on a one to one call.

We regularly have unreliable connections then revert to Zoom which is fine - we are considering moving wholly to Zoom
