SharePoint Online User Permission Report

Question

Hi, we have a need to run SharePoint online user access report and requirement as follow:

1. We have a list of 500 users with email or UPN from CSV file
2. We need to check each of these 500 users to see which SPO site he or she belong to & permission including SharePoint or Teamsite and this report will be generated and output to CSV file

Are there any existing PowerShell to allow us to run above report?

Thanks

Hi @Nguyen, Tee

Per my research, there is no such function to retrieve sharepoint site by users permission. We can only get permission report of sitecollections. Please refer to the following powershell script

#sharepoint online powershell permissions report
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll" 
  
#Function to Get Permissions Applied on a particular Object, such as: Web, List or Item
Function Get-Permissions([Microsoft.SharePoint.Client.SecurableObject]$Object)
{
    #Determine the type of the object
    Switch($Object.TypedObject.ToString())
    {
        "Microsoft.SharePoint.Client.Web"  { $ObjectType = "Site" ; $ObjectURL = $Object.URL }
        "Microsoft.SharePoint.Client.ListItem"
        {
            $ObjectType = "List Item"
            #Get the URL of the List Item
            $Object.ParentList.Retrieve("DefaultDisplayFormUrl")
            $Ctx.ExecuteQuery()
            $DefaultDisplayFormUrl = $Object.ParentList.DefaultDisplayFormUrl
            $ObjectURL = $("{0}{1}?ID={2}" -f $Ctx.Web.Url.Replace($Ctx.Web.ServerRelativeUrl,''), $DefaultDisplayFormUrl,$Object.ID)
        }
        Default
        {
            $ObjectType = "List/Library"
            #Get the URL of the List or Library
            $Ctx.Load($Object.RootFolder)
            $Ctx.ExecuteQuery()           
            $ObjectURL = $("{0}{1}" -f $Ctx.Web.Url.Replace($Ctx.Web.ServerRelativeUrl,''), $Object.RootFolder.ServerRelativeUrl)
        }
    }
  
    #Get permissions assigned to the object
    $Ctx.Load($Object.RoleAssignments)
    $Ctx.ExecuteQuery()
  
    Foreach($RoleAssignment in $Object.RoleAssignments)
    {
                $Ctx.Load($RoleAssignment.Member)

                $Ctx.ExecuteQuery()
                Foreach ($RoleDefinition in $RoleAssignment.RoleDefinitionBindings)
                {
                    $Permissions += $RoleDefinition.Name +";"
                }
