Hi Tommy,

You can do it using the Get-MailboxFolderStatistics cmdlet:

Get-MailboxFolderStatistics -Identity [email protected] | select Name, FolderId, FolderPath

Don't forget to change the Identity ([email protected]) to the corresponding user's identity.

If you need to get the folder ID converted to the proper format to use it in eDiscovery searches or such, then you can use the simple script below:

$mbx = "[email protected]"
$mbxStatistics = Get-MailboxFolderStatistics -Identity $mbx
$folderQueries = @()
foreach ($stat in $mbxStatistics){
    $folderName = $stat.Name
    $folderId = $stat.FolderId;
    $folderPath = $stat.FolderPath;
    $encoding = [System.Text.Encoding]::GetEncoding("us-ascii")
    $nibbler = $encoding.GetBytes("0123456789ABCDEF");
    $folderIdBytes = [Convert]::FromBase64String($folderId);
    $indexIdBytes = New-Object byte[] 48;
    $indexIdIdx = 0;
    $folderIdBytes | select -Skip 23 -First 24 | %{$indexIdBytes[$indexIdIdx++] = $nibbler[$_ -shr 4]; $indexIdBytes[$indexIdIdx++] = $nibbler[$_ -band 0xF]}
    $folderIdConverted = $($encoding.GetString($indexIdBytes))
    $folderDetails = New-Object PSObject
    Add-Member -InputObject $folderDetails -MemberType NoteProperty -Name FolderName -Value $folderName
    Add-Member -InputObject $folderDetails -MemberType NoteProperty -Name FolderId -Value $folderIdConverted
    Add-Member -InputObject $folderDetails -MemberType NoteProperty -Name FolderPath -Value $FolderPath
    $folderQueries += $folderDetails
}
$folderQueries

Again, don't forget to update $mbx variable in this one, too.

Thanks , for the answer. I was thinking folderID would be the same as LastParentFolderID , but I was wrong.

How to get LastParentFolderID ?

The LastParentFolderID parameter specifies the FolderID value of an item before it was deleted. So, talking about a deleted/recoverable item, its LastParentFolderID is the same as the corresponding folder's FolderID.

Get-MailboxFolderStatistics -Identity [email protected] | select Name, FolderId, FolderPath

When using command Get-RecoverableItems I get another FolderID

Get-RecoverableItems -Identity "[email protected]" -FilterItemType IPM.Note -FilterStartTime "11/04/2019 08:00:00 AM" -FilterEndTime "11/27/2019 17:01:59 PM"

Actually that's why I've also provided a script in addition to that cmdlet in my first reply. You'll need to get the FolderID value converted to the same format as in the LastParentFolderID using that script. Just update the $mbx variable and run it right away.
