Exclude messages from Clutter in Office 365 using a transport rule

This post shows you¬†create a transport rule to exclude messages from clutter and provides the code for you to do it automatically. Clutter is a great feature of Office 365 and allows you to focus on the emails that are important to you, but sometimes you need to see emails even if they don’t really require any attention.

Example: Exclude message from clutter based on the email subject

New-TransportRule -Name "Tachytelic Test Rule" -SubjectContainsWords "Sample Subject to bypass clutter" -SetHeaderName "X-MS-Exchange-Organization-BypassClutter" -SetHeaderValue "true"

The rule is created using the “New-TransportRule” cmdlet as per the above.

Enter your own details below to have the Powershell code to exclude your own messages from clutter below:

You can check if the rule worked by sending an email from an external account to your Office 365 tenant and checking the properties of the message when it has arrived:

As per the screenshot above, you should be able to see a entry in the message header which says:

X-MS-Exchange-Organization-BypassClutter: true

That’s all there is to it! Once you have got the messages you need, consider automatically processing them with an Outlook Macro.
