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

    Visio 2013 – new shapes and color scheme

    Today I opened Visio to draw a simple network topology.  The default shapes are different from Office 2010 and have taken more of a Windows 8 (“Modern UI”) look.  Below are some an examples and stencil downloads for drawing the newer style of Microsoft diagrams.
