For the install of the new Teams on Server 2022, it looks like it takes the same .\teamsbootstrapper - p like W10 and W11. Is that correct? Server 2019 use the DSIM install, but I was wondering about 2022 side?

Yes, with 2022 -p is what you need.

Thank you for confirming

You can also use this one: Add-AppProvisionedPackage -online -packagepath “$PSScriptRoot\$Product\MSTeams-x64.msix” -skiplicense | Out-Null

Cool, thanks for that

I thought the AppProvisionedPackage was only for a per user install. But teamsbootstrapper was for multi-user 2022.

the boot strapper is the preferred method using -p and -o switches
