Office 365 provides junk mail filtering options for users to stop unwanted e-mail from being delivered to their inbox. Users have the ability to block email addresses and domains they don't want to receive messages from. Add any email address or domain to your blocked senders list to move these messages directly to your Junk Email folder. Users also have the ability to mark messages as a phishing scam which will submit the e-mail to Microsoft for evaluation.

Users also have the ability to flag messages as a phishing scam or junk. Note: When you mark a message as phishing, it reports the sender but doesn't block them that specific sender from sending you additional messages in the future.
