Powershell Office 365 - Sweep inboxes for deleting all from domain, not specific user

[Warwick_Tech]

Hi All,

 

We use a script to sweep and wipe emails from a specific user

 

Get-Mailbox -ResultSize unlimited | Search-Mailbox -SearchQuery 'from:"[email protected]"' -DeleteContent -force

 

But is there a way to do whole domains?

 

Standard wildcard * and removing the @ show an error.

According to the KQL docs: https://docs.microsoft.com/en-us/exchange/security-and-compliance/in-place-ediscovery/message-properties-and-search-operators you should be able to just specify 'from:constoso.com' to cover a whole domain.
