Attention au côté juridique de cette opération. 

Dans certain cas de figure nous sommes amenés à devoir faire une liste de tout accès externe à différents types de ressources, dans le cas présent nous allons lister l'ensemble des OneDrives avec un partage externe, pour ce faire vous aurez besoin de :

• Powershell 5.1,
• Le module Sharepoint Online,
• un accès Sharepoint Admin.

Vous pouvez maintenant lancer le script en prenant soin de modifier les url de connexion (L2 et L59) 

# Connection to Sharepoint Online
Connect-SPOService -Url https://contoso-admin.sharepoint.com # (Please change the connection URL)

# Get the list of All OneDrives
$AllOneDrive = Get-SPOSite -IncludePersonalSite $true -Limit all -Filter "Url -like '-my.sharepoint.com/personal/'"

# Define variables
$ArrayOneDriveMembers = @()
$SortOneDrive = $AllOneDrive | sort Url
$X = 0

$SortOneDrive | foreach {
    $OneDriveUrl = $_.Url
    $OneDriveOwner = $_.Owner
    $OneDriveStorageQuota = $_."Storage Quota"
    $OneDriveTitle = $_.Title
    # Get Member of current OneDrive
    Try {
        $OneDriveMembers = Get-SPOUser -Site $OneDriveUrl -ErrorAction stop
        }
    Catch {
        Write-Warning $($_)
        Write-Output "$OneDriveUrl;$OneDriveTitle" | Add-Content C:\temp\Onedriveerrors.txt
        }
    
    # Get External members
    $OneDriveExternal = $OneDriveMembers.where({$_.Usertype -eq "Guest"})
    If ($OneDriveExternal.count -ne 0) {
        Write-Host "External Users are present in $OneDriveTitle" -ForegroundColor Green
        $OneDriveExternal.count
        $OneDriveExternal | foreach {
            $DisplayName = $_.DisplayName
            $LoginName = $_.LoginName

            # Store Data
            $ArrayOneDriveMembers += New-Object psobject -Property @{
                OneDriveUrl = $OneDriveUrl
                OneDriveOwner = $OneDriveOwner
                OneDriveStorageQuota = $OneDriveStorageQuota
                OneDriveTitle = $OneDriveTitle
                DisplayName = $DisplayName
                LoginName = $LoginName
                }
            # Release
            $DisplayName = $null
            $LoginName = $null

    $OneDriveOwner = $null
    $OneDriveStorageQuota = $null
    $OneDriveTitle = $null
    $OneDriveMembers = $null
    
    # After 500 connection, reconnect to Sharepoint
    If ($x -eq 500) {
        # Connect to Sharepoint
        Connect-SPOService -Url https://contoso-admin.sharepoint.com 
        $x =0
        }
    $x++
    }
