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

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"
