Spam filtering weak in Exchange Office 365

we are transitioning from Gmail to Outlook 365.  ONe thing i see is that OUtlook 365 is much worse at filtering spam.  Ih ave already set it to level 1 in content Filter, spam messages (this is the strictest spam and bulk mail filtering).  It didn't help much. What else can I do to cut down the types of spam?
