Find and delete an email in Microsoft Purview

When you create a new compliance search, it does not automatically run the search. The commands below creates the search and then runs it.

The search is looking for an email:

$Search=New-ComplianceSearch -Name "Remove an email" -ExchangeLocation All -ContentMatchQuery ‘(From:user@example.com) AND (Subject:"An email subject") AND (Received:M/DD/YYYY..M/DD/YYYY)’
Start-ComplianceSearch -Identity $Search.Identity

To delete the results of the above search, run:

New-ComplianceSearchAction -SearchName "Remove an email" -Purge -PurgeType SoftDelete

SoftDelete removes the email, but it is still recoverable. HardDelete removes the email and it is not recoverable. It does not move it to the recipient's Deleted Items folder.
