Sent items are default not saved to the sent items folder of the shared mailbox, with following commands you can save a copy to the sent items folder of the shared mailbox.
First, login to exchange online with powershell (https://www.productivv.be/2022/12/01/powershell-exchange-online-commands/)
Set-Mailbox <shared mailbox> -MessageCopyForSentAsEnabled $trueBecause of old installations, TeamViewer is sometimes installed in the 64 bit version and sometimes in the 32 bit version. Since I would like to have a clear overview in Intune, I created the script below.
$tv = "C:\Program Files\TeamViewer\TeamViewer.exe", "C:\Program Files (x86)\TeamViewer\TeamViewer.exe"
$result = ($tv | Test-Path) -notcontains $true
if ($result) {
Write-Output "Not installed"
exit 1
}
else {
write-output "Teamviewer detected, exiting"
exit 0
}
