If you want to be sure that you receive particular messages, you can create an Exchange transport rule that makes sure that these messages bypass your clutter folder. Check out Use Clutter to sort low priority messages in Outlook Web App for more info on Clutter.

For additional management tasks related to transport rules, check out Mail flow rules (transport rules) in Exchange Online and the New-TransportRule PowerShell topic. If you're new to PowerShell, check out the following topics for help on using Powershell:

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

  1. In the Exchange admin center, navigate to mail flow > Rules. Click Add Icon and then choose Create a new rule....

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

Art example: If subject contains meeting, bypass clutter

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

New-TransportRule -Name <name_of_the_rule> -SubjectContainsWords "Meeting" -SetHeaderName "X-MS-Exchange-Organization-BypassClutter" -SetHeaderValue "true"
ImportantImportant:
In this example, both "X-MS-Exchange-Organization-BypassClutter" and "true" is case sensitive.

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

You can check email message headers to see if the email messages are landing in the Inbox due to the clutter transport rule bypass. Pick an email message from a mailbox in your organization that has the clutter bypass transport 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.

NoteNote:
Calendar items, like meetings accepted, sent or declined won't have these headers on them. We're working on extending clutter capabilities to these calendar items soon.
