VIDEO – How to Add Contact for other users with MS Graph API

Wanted to share a quick demo for how to query and create Exchange Contacts for another user in Office 365 tenant with MS Graph API.   Biggest challenge was permission grant in two places (1) MS Graph API in Azure Applications and (2) Exchange Folder grant Owner to user executing the MS Graph API.  Updated blog post with second video to execute Graph API from PowerShell for automation and scheduling.   Cheers shades_smile

Video 1 – Graph Explorer Web GUI

Video 2 – Graph API from PowerShell

PowerShell – Grant Exchange Folder

$Session = New-PSSession -ConfigurationName "Microsoft.Exchange" -ConnectionUri "https://outlook.office365.com/powershell-liveid/" -Credential $UserCredential -Authentication Basic -AllowRedirection
Import-PSSession $Session
Add-MailboxFolderPermission -Identity "george@spjeff.com:\Contacts" –User "spjeff@spjeff.com" –AccessRights "Owner"

PowerShell – Execute Graph API

# from https://blog.mastykarz.nl/building-applications-office-365-apis-any-platform/
# Config
$clientID = "34f34d49-86b7-4437-a332-6fecaf95a244"
$tenantName = "spjeff.onmicrosoft.com"
$ClientSecret = "secret-goes-here"
$Username = "spjeff@spjeff.com"
$Password = "password-goes-here"
# Access Token
$ReqTokenBody = @{
    Grant_Type    = "Password"
    client_Id     = $clientID
    Client_Secret = $clientSecret
    Username      = $Username
    Password      = $Password
    Scope         = "https://graph.microsoft.com/.default"
} 
$TokenResponse = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$TenantName/oauth2/v2.0/token" -Method POST -Body $ReqTokenBody
$TokenResponse

    VIDEO – MS Graph Quick Start (Angular CLI)

    Demo of the Microsoft Graph “Quick Start” which generates a full code project with a new App ID (Client ID).    Azure Active Directory (AAD) manages a registration of application ID paired with API permission grants for which API calls can be made.   From there, the client side JavaScript application can invoke HTTP GET to fetch JSON data for the allowed MS Graph API endpoints.   Cheers!  shades_smile
