Hello,

Office 365 Mailbox Anti Spam is complex, previously we saw ho to configure the global anti spam solution for Office 365 in Exchange Online.Today we’ll see how to override those global settings on individual mailboxes. Indeed, Office 365 provide us a way to set custom anti spam settings on each mailboxes with the cmdlet :

Set-MailboxJunkEmailConfiguration

Office 365 Mailbox Anti Spam

Example :

Set-MailboxJunkEmailConfiguration emmanuel.demilliere@itfordummies.net -TrustedSendersAndDomains @{Add='itfordummies.net','microsoft.com'}

Set Office 365 custom Anti Spam setting on a mailbox

You can check if it worked with :

Get-MailboxJunkEmailConfiguration

With that last cmdlet you can also see what each users has white/blacklisted from Outlook.
