Powershell script to view all OneDrive files and who has access to them

I'm pretty new to PowerShell and wanted to know if there was a way to pull all files from OneDrive and see who has access to them?

I was hoping to find an easier way to see whether or not a file is shared and if it is, who is it shared with internally and externally.

As of right now, I know if you go through each user account, you can see this information. I'm curious to know if there is a faster way to that.

You can call OneDrive List Shared File Rest API to finish the job.

You need register an application to get proper access to your OneDrive according to https://dev.onedrive.com/app-registration.htm

Then you can make use the code below.

$ClientId = "<Your application client id>" # your application clientid 
$SecrectKey = "<Your application key>" # the secrect key for your application 
$RedirectURI = "<Your web app redirect url>" # the re-direct url of your application 

Function List-SharedItem 
{ 
    [CmdletBinding()] 
    Param 
    ( 
        [Parameter(Mandatory=$true)][String]$ClientId, 
        [Parameter(Mandatory=$true)][String]$SecrectKey, 
        [Parameter(Mandatory=$true)][String]$RedirectURI 
    ) 

    # import the utils module 
    Import-Module ".\OneDriveAuthentication.psm1" 

    # get token 
    $Token = New-AccessTokenAndRefreshToken -ClientId $ClientId -RedirectURI $RedirectURI -SecrectKey $SecrectKey 

    # you can store the token somewhere for the later usage, however the token will expired 
    # if the token is expired, please call Update-AccessTokenAndRefreshToken to update token 
    # e.g. 
    # $RefreshedToken = Update-AccessTokenAndRefreshToken -ClientId $ClientId -RedirectURI $RedirectURI -RefreshToken $Token.RefreshToken -SecrectKey $SecrectKey 

    # construct authentication header 
    $Header = Get-AuthenticateHeader -AccessToken $Token.AccessToken 

    # api root 
    $ApiRootUrl = "https://api.onedrive.com/v1.0" 

    # call api 
    $Response = Invoke-RestMethod -Headers $Header -Method GET -Uri "$ApiRootUrl/drive/shared" 

    RETURN $Response.value 
} 

# call method to do job 
$Results = List-SharedItem -ClientId $ClientId -SecrectKey $SecrectKey -RedirectURI $RedirectURI 

# print results 
$Results | ForEach-Object { 
    Write-Host "ID: $($_.id)" 
    Write-Host "Name: $($_.name)" 
    Write-Host "ParentReference: $($_.parentReference)" 
    Write-Host "Size: $($_.size)" 
    Write-Host "WebURL: $($_.webUrl)" 
    Write-Host 
}
