Office 365: Extraire dans un fichier CSV une liste de tous les Teamsites présents dans votre tenant Office 365

 Une fois la migration terminée, il est primordial de surveiller son instance Office 365 en faisant une extraction de tous les sites du tenant dans un fichier Excel:

[string]$username = "YourAdminAccount@yourtenant.onmicrosoft.com"
[string]$PwdTXTPath = "C:\SECUREDPWDFOLDER\ExportedPWD-$($username).txt"
[string]$ExportAllUserLogin = ""

function Load-DLLandAssemblies
{
     [string]$defaultDLLPath = ""

    # Load assemblies to PowerShell session

    $defaultDLLPath = "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.dll"
    [System.Reflection.Assembly]::LoadFile($defaultDLLPath)

    $defaultDLLPath = "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.Runtime.dll"
    [System.Reflection.Assembly]::LoadFile($defaultDLLPath)

    $defaultDLLPath = "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.Online.SharePoint.Client.Tenant.dll"
    [System.Reflection.Assembly]::LoadFile($defaultDLLPath)
}

cls

$secureStringPwd = ConvertTo-SecureString -string (Get-Content $PwdTXTPath)
$adminCreds = New-Object System.Management.Automation.PSCredential $username, $secureStringPwd

$CSVFileToExport = "C:\YOUREXPORTFOLDER\AllSiteCollectionInformation.csv"
if (Test-Path $CSVFileToExport) {
    Remove-Item $CSVFileToExport -Force
}

$ExportSiteCollectionList = ""

#Retrieve all site collection infos
$sitesInfo = Get-SPOSite -Template "STS#0" -Limit ALL | Sort-Object -Property url | Select *
[int]$i = 1;

Write-Host "--------------------------------------------------------------------------------------------"
#Retrieve and print all sites
foreach ($site in $sitesInfo)
{
    $ExportAllUserLogin = ""
    Write-Host "SiteColl Number:", $i, "- of:", $sitesInfo.Count;
    $i += 1;
   
    Write-Host "SPO Site collection:", $site.Url, "- Title:", $site.Title
    Write-Host "   => External Sharing:", $site.SharingCapability
    Write-Host "   => Site Template Used:", $site.Template
    Write-Host "   => Storage Quota:", $site.StorageQuota, "- Storage used:", $site.StorageUsageCurrent
    Write-Host "   => Percent Usage:", $($site.StorageUsageCurrent / $site.StorageQuota * 100), "%"
   
    Write-Host "   => Resource Quota:", $site.ResourceQuota, "- Resource used:", $site.ResourceUsageCurrent
    #Write-Host "   => Owner:", $site.Owner

    #Get-SPOUser -Limit ALL -Site $site.Url -IsSiteCollectionAdmin $true < NOT WORKING
   
     $AllUsers = Get-SPOUser -Limit ALL -Site $site.Url #| FT LoginName, IsSiteAdmin -AutoSize #%{if($_.IsSiteAdmin -eq $True)
    $AllUsers | %{if($_.IsSiteAdmin -eq $True) {
                $ExportAllUserLogin += $_.LoginName + '|';
        }
    }

    Write-Host "--------------------------------------------------------------------------------------------"

    $ExportSiteCollectionList += @(
          [pscustomobject]@{
            SiteURL = $site.Url
            SiteTitle = $site.Title
            SharingCapability = $site.SharingCapability
            StorageQuota = $site.StorageQuota
            StorageUsageCurrent = $site.StorageUsageCurrent
            PercentQuotaUsed = $($site.StorageUsageCurrent / $site.StorageQuota * 100)
            SiteCollAdmin = $ExportAllUserLogin
            }  )

}

Write-Host $ExportSiteCollectionList

$ExportSiteCollectionList | Export-Csv -Path  $CSVFileToExport -Encoding UTF8

Write-Host " ---------------------------------------------- "

Vous pouvez ensuite prendre ce fichier CSV et l’utiliser pour vos besoins d’administration ou de listing/reporting.
