You can use [[CyberDrain Improved Partner Portal (CIPP)]] to deploy [[Transport Rules]] to [[Exchange Online]] environments. CIPP Transport Rule Templates are written in [[JSON]]. An example is below. ```JSON {     "name": "Mark onmicrosoft.com emails as spam",     "comments": "Created by X.",     "Priority": 1,     "SetSCL": 6,     "FromAddressContainsWords": "*.onmicrosoft.com"   } ``` I start with basics and then use the [New-TransportRule Microsoft documentation](https://learn.microsoft.com/en-us/powershell/module/exchange/new-transportrule?view=exchange-ps) to define all the settings I need.
