Office365 Spam

[reprised]

Hi all

 

One of our members of staff has received an email from a dodgy video/por n website which asks him to activate. It probably is a student who's used the staff email address to create the account. We are still learning office 365 and was wondering what the best way to deal with this spam. I have have added the email domain to the blocked list but is there anything else we can do to block these kinds of emails? Do you guys run keyword filtering of emails in office365?
