Unread email in Office 365

[Douglas_L_McDuffie]

I need a method to obtain all the unread emails for all our tenants. I am somewhat comfortable using PowerShell, but I'm not an expert. 

Thank You,

You can do that using the new-compliancesearch cmdlet, nice example here which you can adjust https://sites.google.com/a/cohberg.com/default/home/daily-postings/unreademailsininbox-office365powe...
