Quick Run Down

    1.)Registered App

    2.) PowerShell Example

    3.) Troubleshooting

Registered App

  • In https://portal.azure.com > Registered Apps > Create a new app for a single tenant.
  • "Microsoft Graph - API"
  • Add delegate permissions : App Only
  • SharePoint needs "sites.read.all"
  • User audits might need users.read.all (WIP)
  • Approve the Admin Consent
  • Generate client secret info, export Value, Client/APP ID, and Tenant ID to another notepad for use in the connection script below

PowerShell Example

    #GRAPH API INFORMATION

    $TenantId = ""
    $ClientId = ""
    $ClientSecret = ""

    #CONNECT TO GRAPH

    $SecureSecret = ConvertTo-SecureString -String $ClientSecret -AsPlainText -Force

    $ClientCredential = New-Object System.Management.Automation.PSCredential (
    $ClientId,
    $SecureSecret
    )

    Connect-MgGraph `
    -TenantId $TenantId `
    -ClientSecretCredential $ClientCredential `
    -NoWelcome
