Microsoft 365 / SharePoint online : PowerShell script – to get the list of SharePoint sites where given group has permission and export sites to CSV file

Hi All,

Greetings for the day 🙂 LIFE IS BEAUTIFUL 🙂

Today something new – PowerShell script 🙂

Background : My management want to check on which SharePoint sites if one particular group has permissions. So this script 🙂

Details :

• High level steps as follows:
  • Connect to our SharePoint tenant
  • Get all sites from the Tenant
  • For every site get all Groups
  • For every group check if the group which we want to verify is available in group list which is fetched from above step
  • If above condition is true then write the given SharePoint site URL to CSV file

Detailed Steps – PowerShell script :

• Connect to our SharePoint tenant using – Connect-SPOService cmdlet

#Connect to our M365 tenant - Please change here the tenant SharePoint site admin URL
Connect-SPOService "https://knowledgejunction1-admin.sharepoint.com/"

• Fetch all sites from our tenant using – Get-SPOSite -Limit All

#Get all SharePoint sites from our Tenant
$spoSites = Get-SPOSite -Limit All

• Loop through each site and get all the groups of site

#verifying the groups of every site
foreach ($spoSite in $spoSites)
{
    Write-Host $spoSite.Url -ForegroundColor "Yellow"
    
    #fetching all the groups from the site
    $groups = Get-SPOSiteGroup -Site $spoSite.Url
    

• Next, we will loop through each group and check if respective site contains the group which we need to verify
• If above condition is TRUE then write the SharePoint site URL to CSV file. Here we are using – Out-File cmdlet

 # verifying each group    
    foreach ($group in $groups)
    {
        #check for our specific group
        if($group.Title.Contains("TeamsDemo_16062020.11.28 Members"))
        {
            Write-Host $group.Title -ForegroundColor "Cyan"   

            # writing the SharePoint site URL to CSV file
            $spoSite.Url | Out-File -FilePath $Path -Append
            break;
        }         
                
    }#foreach ($group in $groups)
           
 }#foreach ($spoSite in $spoSites)

Complete PowerShell script :

<#  
    Outputs a .csv file of records that represent list of SPO sites which contains the specific given group -  from the tenant it is run in . Result feature records will include:
        - SharePoint site URL

#>

#CSV file path
$Path = 'c:\sitegroups.csv'

#Connect to our M365 tenant - Please change here the tenant SharePoint site admin URL
Connect-SPOService "https://knowledgejunction1-admin.sharepoint.com/"

#Get all SharePoint sites from our Tenant
$spoSites = Get-SPOSite -Limit All

#preparing array list
#$spoSitesListings = [System.Collections.ArrayList]@()

#verifying the groups of every site
foreach ($spoSite in $spoSites)
{
    Write-Host $spoSite.Url -ForegroundColor "Yellow"
    
    #fetching all the groups from the site
    $groups = Get-SPOSiteGroup -Site $spoSite.Url
    
    
    # verifying each group    
    foreach ($group in $groups)
    {
        #check for our specific group
        if($group.Title.Contains("TeamsDemo_16062020.11.28 Members"))
        {
            Write-Host $group.Title -ForegroundColor "Cyan"   

            $spoSite.Url | Out-File -FilePath $Path -Append
            break;
        }         
                
    }#foreach ($group in $groups)
           
 }#foreach ($spoSite in $spoSites)
