Windows 11 builds after 23H2 have the new Outlook app preinstalled for all users. Currently, there isn't a way to block the new Outlook from being installed - if you prefer not to have new Outlook show up on your organization's devices, you can remove it after it's installed as part of the update.

This is false. It's been known for some time you can remove the Appx package (before any user logons on), and delete the Orchestrator task which tries to update it again.

From your Unattended file, run these commands in the specialize pass:
Code: 
powershell -nop -C "Remove-AppxProvisionedPackage -AllUsers -Online -PackageName (Get-AppxPackage Microsoft.OutlookForWindows).PackageFullName"
reg delete HKLM:\SOFTWARE\Microsoft\WindowsUpdate\Orchestrator\UScheduler_Oobe\OutlookUpdate /f

I had no issue removing Outlook (New) and having it stay removed. As long as Mail & Calendar is also removed, Outlook (New) wont return, in my experience. It only returns to replace Mail & Calendar if mail & Calendar is seen to be present.

Removing Outlook (New) from a live system isn't a problem, because your removal will create a Deprovisioned key. Which Windows respects moving forward.

The problem was users would remove Outlook from the install image, and the hidden task would install it anyway. It's like how DevHome, and EdgeUpdater sneak into your system. That's by deliberate design, because MS knows you want to remove it!

Yes, there was a whole thread with someone trying to remove/prevent Outlook (New) from the automated instale script without success, not that I kept up with the ending to that thread.
