Use mail flow rules so messages can bypass Clutter

If you want to be sure that you receive particular messages, you can create an Exchange mail flow rule (also known as a transport rule) that makes sure that these messages bypass your clutter folder. Check out Use Clutter to sort low-priority messages in Outlook for more info on Clutter.

For additional management tasks related to mail flow rules, check out Mail flow rules (transport rules) in Exchange Online and the New-TransportRule PowerShell topic. If you're new to Exchange Online PowerShell, check out Connect to Exchange Online PowerShell.

What do you need to know before you begin?

Use the Exchange admin center to create a mail flow rule to bypass the clutter folder

This example allows all messages with title "Meeting" to bypass clutter.

  1. In the Exchange admin center (EAC), go to Mail flow > Rules. Click New Add Icon and then choose Create a new rule....

    Art example: If subject contains meeting, bypass clutter

  2. After you're done creating the new rule, click Save to start the rule.

Use Exchange Online PowerShell to create a mail flow rule to bypass the clutter folder

This example allows all messages with title "Meeting" to bypass clutter.

New-TransportRule -Name "<Unique rule name>" -SubjectContainsWords "Meeting" -SetHeaderName "X-MS-Exchange-Organization-BypassClutter" -SetHeaderValue "true"

Important

In this example, both X-MS-Exchange-Organization-BypassClutter and true are case sensitive.

For detailed syntax and parameter information, see New-TransportRule.

How do you know this worked?

You can check email message headers to see if the email messages are landing in the Inbox due to the Clutter mail flow rule bypass. Pick an email message from a mailbox in your organization that has the Clutter bypass mail flow rule applied. Look at the headers stamped on the message, and you should see the X-MS-Exchange-Organization-BypassClutter: true header. This means the bypass is working. Check out the View the Internet header information for an email message topic for info on how to find the header information.

Note

Calendar items (accepted, sent, or declined meetings notifications) won't contain this header. We're working on extending Clutter capabilities to these calendar items soon.
