M365 Changelog: (Updated) Microsoft Defender for Office 365 to stop honoring ReportJunkEmailEnabled in OwaMailboxPolicy
MC455512 – Updated November 8, 2022: Microsoft has updated the content below with additional information. Thank you for your feedback.
Beginning November 25, 2022, ReportJunkEmailEnabled property in OwaMailboxPolicy will no longer work in favor of the consolidated User reported settings page in the Microsoft 365 Defender portal. From the Settings page, you’ll be able to customize the way users report messages in Outlook as phishing, junk, or not junk. Reported emails will be sent to the mailbox of your choice and appear on the Submissions page of the Microsoft 365 Defender portal.
When this will happen:
We’ll be gradually rolling this out to customers around November 25th, 2022, and the roll out will be completed by December 10th, 2022.
How this will affect your organization:
You are receiving this message because you as an admin might be using this setting or might be looking to use this setting in the future.
Use the Get-OwaMailboxPolicy to see what your ReportJunkEmailEnabled property has been configured to, and then make sure it’s set up that way in the Settings page.
Administrators will no longer be able to use this property to turn end user reporting on or off in outlook, when this change is implemented. Instead, they will use the Settings page with its added functionality.
What you need to do to prepare:
Instead of using ReportJunkEmailEnabled property in OwaMailboxPolicy, Microsoft recommends using user reported settings page in the Microsoft 365 Defender portal to manage how users report messages.
