We have requirement to fetch report of active or in use/not in use Mail contacts & Mail users from Exchange admin center and if can get report for last 6 or 3 months active contacts as we need to perform some contact cleanup activity. Is there a way to get it from PowerShell commands/ Exchange reporting....?
Already checked for Get-MessageTrace. So, if there can be an alternative to get active mail contacts details and any PowerShell script available???
