On Win10 2004+, it should install without jumping through most below hoops. For older versions such as popular 1809, I'm summarizing the relevant post:

1. Install the latest Windows-Updates (2024-01).
2. Install Edge WebView2 Runtime (or Edge itself, which contains WebView2):
   https://developer.microsoft.com/en-us/microsoft-edge/webview2?form=MA13LH
3. Allow msix sideloading (run Command Prompt as administrator):

   reg add HKLM\SOFTWARE\Policies\Microsoft\Windows\Appx /v AllowAllTrustedApps /t REG_DWORD /d 1 /f

   Enabling “Developer Mode” manually or via Group Policy should also work.

4. Download Teams MSIX:
   https://learn.microsoft.com/en-us/microsoftteams/new-teams-bulk-install-client#option-1b-download-and-install-new-teams-using-an-offline-installer

5. Install MSTeams via MSIX (run PowerShell as administrator):

   Add-AppProvisionedPackage -Online -PackagePath "$PSScriptRoot\MSTeams-x64.msix" -SkipLicense

 

It may work with older builds of Win10 1809 as well. Regarding Edge and Edge WebView2, it's probably the best to have both formally installed for best compatibility with stuff requiring WebView2. When both are correctly installed, there's technically just one copy of files for specific Edge version on disk, they're hardlinked together.

I had Developer Mode enabled from before, so 3rd step was skipped. I wonder what it would say otherwise. In the last step, I just specified absolute path to where .msix file was downloaded, which was in Downloads folder.

Anyone tested this with an old version of WebView2 like 109 https://www.catalog.update.microsoft.com/Search.aspx?q=webview2 Runtime version 109 on Vista/7/8/8.1 ?

Despite the message that said Teams would stop functioning on 1809 as of July 1st, it still does work and can connect with other versions (modern Classic, web, APK) of Teams on newer versions of Windows, at least as of July 3.
