Disable Exchange 2010 Content Filtering← Back
I have been trying to work out why emails were still being moved to user’s Junk Email folder in Outlook 2007 even though Junk Email Filtering was turned off by Group Policy. It turns out Exchange 2010 has it’s own Content Filtering which can move emails to the Junk Email folder regardless of your Outlook setting.
To disable it for a single user you need to run the following from the EMS:
Set-MailboxJunkEmailConfiguration -Identity "User Name" -Enabled $false
To disable it for all users on all mailbox databases, run:
Get-Mailbox -Database * | Set-MailboxJunkEmailConfiguration -Enabled $false
When running the disable command, you may see a message that the user needs to login to Outlook Web App before they can manage the setting. This is because the setting is primarily to provide feature equality between the Outlook client and OWA. If the user hasn’t logged in to OWA, server-side Junk Email filtering will not be enabled for them until the first time they do.
