PowerShell to Get All SharePoint Online Site Collections Inventory

Have you ever wanted to prepare an inventory of SharePoint Online sites in your tenant? Maybe you want to find out if any unused sites can be deleted? PowerShell to the rescue! In this post, we will take a look at how to use PowerShell to inventory all of the sites in your SharePoint Online tenancy. This will help you keep track of which sites are being used in your organization and what content is stored on them. Let’s get started!

Let’s get a list of SharePoint Online sites using PowerShell:

Import-Module Microsoft.Online.SharePoint.Powershell -DisableNameChecking

#Config Parameters
$AdminSiteURL="https://crescent-admin.sharepoint.com"
$ReportOutput="C:\Temp\SPOStorage.csv"

#Get Credentials to connect to SharePoint Admin Center
$Cred = Get-Credential

#Connect to SharePoint Online Admin Center
Connect-SPOService -Url $AdminSiteURL -Credential $Cred

#Get All site collections
$SiteCollections = Get-SPOSite -Limit All
Write-Host "Total Number of Site collections Found:"$SiteCollections.count -f Yellow

#Array to store Result
$ResultSet = @()

#Loop through each site collection and retrieve details
Foreach ($Site in $SiteCollections)
{
    Write-Host "Processing Site Collection :"$Site.URL -f Yellow

    #Get site collection details    
    $Result = new-object PSObject
    $Result | add-member -membertype NoteProperty -name "Title" -Value $Site.Title
    $Result | add-member -membertype NoteProperty -name "Url" -Value $Site.Url
    $Result | add-member -membertype NoteProperty -name "LastContentModifiedDate" -Value $Site.LastContentModifiedDate
    $Result | add-member -membertype NoteProperty -name "Status" -Value $Site.Status
    $Result | add-member -membertype NoteProperty -name "LocaleId" -Value $Site.LocaleId
    $Result | add-member -membertype NoteProperty -name "LockState" -Value $Site.LockState
    $Result | add-member -membertype NoteProperty -name "StorageQuota" -Value $Site.StorageQuota
    $Result | add-member -membertype NoteProperty -name "StorageQuotaWarningLevel" -Value $Site.StorageQuotaWarningLevel
    $Result | add-member -membertype NoteProperty -name "Used" -Value $Site.StorageUsageCurrent
    $Result | add-member -membertype NoteProperty -name "CompatibilityLevel" -Value $Site.CompatibilityLevel
    $Result | add-member -membertype NoteProperty -name "Template" -Value $Site.Template
    $Result | add-member -membertype NoteProperty -name "SharingCapability" -Value $Site.SharingCapability
    
    $ResultSet += $Result
}  
 
#Export Result to csv file
$ResultSet |  Export-Csv $ReportOutput -notypeinformation
 
Write-Host "Site Quota Report Generated Successfully!" -f Green

and the result:
