New Teams VDI versions, the current version we see when downloading the teamsbootstrapper.exe is 24137.2216.2931.2440, which is an old version from 6/17/2024. "Using the teamsbootstrapper.exe -p command always guarantees the latest new Teams client is installed", the latest version in that last link shows latest GA version is 24193.1805.3040.8975, but where is that latest version? Moreover, the New Team VDI fix list mentions version 24215.1007.3082.1590 or higher to fix some issues, but where is that version available to download?

Latest version can be found here https://go.microsoft.com/fwlink/?linkid=2196106

Why don’t you just use an Evergreen script to always download the latest version? You can choose between various scripts on GitHub, most of them using the Powershell Evergreen module from @Aaron Parker

Issue is resolved, admin was using an outdated MS link (do NOT use this link when needing to download the "latest" teamsbootstrapper.exe) https://learn.microsoft.com/en-us/microsoftteams/new-teams-bulk-install-client
