Microsoft has been working on a redesigned version of Microsoft Teams for Windows 10 and Windows 11. Unlike the current desktop client, Microsoft Teams 2.0 is moving from the Electron to Edge Webview 2 and switching to React.js (open-source front-end JavaScript library) from Angular.

The brand new Teams client was first announced during the Windows 11 event and it is currently being referred to as “Teams 2.0”. With Microsoft Teams 2.0, Microsoft is planning to target consumers and make its popular video collaboration tool available on more devices.

Microsoft Teams 2.0 is based on Edge WebView2 and it will be initially exclusive to Windows 10 and Windows 11. With Edge WebView 2, Microsoft will be using embedded web technologies (HTML, CSS, and JavaScript) and Chromium rendering engine in Microsoft Teams.

Thanks to a leaked build, we have now managed to download and install an early preview of the brand new Microsoft Teams app.

The new app is built around the Microsoft Teams web, but it uses Edge (Chromium) WebView, which means Microsoft has removed the browser’s address bar and users can run Microsoft Teams in a separate window like the current desktop app.

The browser’s extension and main menu are also gone, but you can find traces of Edge browser when you right-click anywhere in the app’s window.

In our tests, we observed that Teams 2.0 is significantly faster than the current desktop app and it can run smoothly on lower-end devices with 4GB of RAM and Core i3 (10th-gen) without suffering major hits to their performance.

Teams memory usage has also dropped and overall performance is significantly better than than the current platform. In fact, Microsoft Teams can now launch instantly and it won’t get stuck on the loading screen, thanks to the Microsoft Edge background processes and WebView integration.

This new Teams client has been designed with consumers and performance in mind, and it will offer an “always up-to-date nature” thanks to the use of Edge WebView.

In other words, users can easily download and update the client. Microsoft has also enabled integration with all Windows 10 features, such as native notifications, including the upcoming Teams chat app in Windows 11.

All necessary Microsoft Teams features are available in the new version, but advanced controls are currently missing. For example, the functionality of the together mode is limited and users cannot make changes to the noise cancellation settings.

The new web-based Teams client is currently under development and Microsoft will enable support for features like multiple accounts and improved PowerPoint integration.

Closer Look: Microsoft Teams integration in Windows 1​

Microsoft has included Teams by default in Windows 11 and has promised deeper integration with the OS. When you boot up the OS for the first time, you'll notice a purple chat bubble icon on your taskbar, representing the capability. If you hover over the icon, you'll notice that it is actually referred to as "Chat", the same branding is present in the Windows Settings app too.

When you click on it to launch it, you will be asked to sign up. The only sign-up method that Microsoft allows right now is with a personal account. If you want to sign in with a work or school account, you have a button at your disposal that will direct you to download the "full" Teams app. As is evident from the "Meet and chat with friends and family" tagline when you launch the app for the first time, Microsoft seems to be positioning this as an online chat app for personal use rather than a hybrid one which combines personal use with work or education as well. I'm not sure if the company plans to expand this offering or maybe have different Teams versions for different SKUs of the OS, but this is at least how it is on Windows 11 Home's Beta channel right now. Provided that you do have an eligible personal account, the sign-in process is fairly straightforward. You'll get the option to sync your contacts from Outlook and Skype, and you'll be up and running in a matter of seconds.

Once you sign-in, you'll first be shown the "full" Teams experience, which is labeled as a "Preview" right now. If you've used the standalone Teams app before, you'll notice a very familiar UI. The chats and contacts are on the left side, with some options like Activity, Chat, and Calendar on the left. You can access settings from the ellipsis menu on the top-right, and it will show you some basic configurations related to auto-start, notifications, appearance, and privacy. Of course, the regular Teams capabilities such as chatting, groups, and Meet Now are also advertised on launch. You can also be notified about interactions via Windows notifications and reply to messages inline, and although Microsoft makes a big fuss about it in its blog post, I think it's a pretty basic feature and I would have been extremely surprised if it wasn't there.

Although Microsoft has talked about how it is shifting Teams' architecture away from Electron and AngularJS to Edge Webview2 and React, which will result in lower memory consumption, "work life scenarios, release predictability, and scale up for the client", I personally have not noticed any significant change in terms of how this translates to actual usage yet. This statement is based only on real-world use, which I think that matters more than benchmarks. I'm tempted to say that the launch experience seems slightly faster but once the app is loaded, performance seems very similar to the standalone app to me right now.

All the capabilities that we have talked about so far are available in the standalone Teams app too. So what deeper integration is Microsoft boasting about? Turns out that clicking on the Teams icon in the taskbar opens up a flyout UI through which you can quickly open pop-up chats, see your recent activity, start Meet Now calls, and search for contacts. If you want to do something else, you can also click on "Open Microsoft Teams" button at the bottom which will open the full Teams app.

While this is certainly an interesting direction in terms of making Teams a more integrated experience with Windows 11, I'm a bit disappointed with the lack of polish, at least in its current state. I'll go through my grievances one by one.

While you can open multiple independent pop-up chats, I was quite disappointed to know that there seems to be no support for Snap Layouts and Snap Groups when you hover over the "window" icon. The capability is probably my favorite in Windows 11 and I find it a bit odd that despite being touted as a native integration with the OS, Teams' pop-chats have to be snapped using the Windows + directional keys or by manually dragging the window. Not a good look from a multitasking perspective.

Secondly, the context menus in the flyout UI are surprisingly lackluster. When I right-click on any of my synced contacts, I get no context menu at all. When I right-click on a recent contact (screenshot above), I only get a couple of options, namely Audio call and Video call. If I want to mute, hide, or delete a chat, I have to open the full Microsoft Teams app.

It's just odd, really. It actually got me wondering that maybe I'm using an outdated version of the app but when I went to the "About Teams" section, I found out that I was using the most up-to-date version. This seems to be another example of Microsoft's "ship first, fix later" mantra. I fully understand that I'm using a preview version of the OS, but hey, Windows 11's general availability is less than 10 days away, and I find it unlikely that the company will fix this and other issues I have talked about so far before then. If it does, kudos to them and I'll update this piece with a note at the end.

Remember I talked about having the ability to delete items only via the full Microsoft Teams app? Turns out even that does not work as expected sometimes. I started a "Meet Now" interaction just for testing and then closed it. I keep trying to delete it and mark it as read but to no avail. It still shows up as an "unread" chat with the annoying notification bubble both in the taskbar and inside the Teams app. You can see a screenshot of this instance above.

I have to emphasize that this is not a widespread issue in the sense that it does not apply to all of my chats, but the fact that it is inexplicably tied to this one chat is a bug that's bugging the hell out of me (pun intended).

Finally, while it's possible to send a message directly to a phone number (or email account), SMS chat is only available in the U.S., UK, Canada, Mexico, Brazil, Colombia, and India. All recipients in other countries get a notification on their phone number, and are asked to download the Teams app. I know I can't entirely blame Microsoft for this because it's likely related to telecom operators as well, but it's again disappointing to see that an OS that is supposed to rollout globally does not support a mode of communication across more countries. I know we live in an increasingly internet-connected world where SMS as a method of message delivery is dying, but if it's supported in a handful of countries, it should be supported in more too. Maybe Microsoft will add more countries with the passage of time, but that's how it is right now.
