SharePoint Online: Get All Users in Site Collection using PowerShell

Requirement: SharePoint Online PowerShell to Get All Users in Site Collection

While my another post addresses How to Get All Users and Groups in SharePoint Online, this post aims to get all users of the SharePoint site collection.

SharePoint Online: PowerShell Get All Users of the Site Collection
Here is the SharePoint Online CSOM to get all users

#Load SharePoint CSOM Assemblies
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"

#Site collection URL
$SiteURL="https://crescent.sharepoint.com"

#Setup Credentials to connect
$Cred = Get-Credential
$Cred = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)

#Initialize the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = $Credentials 

#Get all users of the site collection
$Users = $ctx.Web.SiteUsers
$ctx.Load($Users) 
$ctx.ExecuteQuery()

#Get User name and Email
$Users | ForEach-Object { Write-Host "$($_.Title) - $($_.Email)"}

PowerShell to Get All Users from All Site Collections in SharePoint Online:
Here is the SharePoint Online Management Shell way to get all users from all site collections in the tenant.

Import-Module Microsoft.Online.Sharepoint.PowerShell -DisableNameChecking

$AdminSiteURL="https://crescent-admin.sharepoint.com/"

#Connect to SharePoint Online Admin
Write-host "Connecting to Admin Center..." -f Yellow
Connect-SPOService -url $AdminSiteURL -Credential (Get-Credential)

Write-host "Getting All Site collections..." -f Yellow
#Get each site collection and users
$Sites = Get-SPOSite -Limit ALL

Foreach($Site in $Sites)
{
    Write-host "Getting Users from Site collection:"$Site.Url -f Yellow
    Get-SPOUser -Limit ALL -Site $Site.Url | Select DisplayName, LoginName
}

This PowerShell script gets all users in SharePoint Online.
