powershell script to export all external outlook contacts to a CSV file

Hi Experts,

Is there a PowerShell script available to search for all mailboxes hosted in MS365 and export all external contacts per mailbox onto a CSV file? 

I would like to get a report of all outlook external contacts per mailbox

You will have to use EWS or the Graph API for this. Here's a sample script: https://github.com/gscales/Powershell-Scripts/tree/master/EWSContacts
