Office 365 - Content filtering

[Sanm2009]

Is anyone using external content filtering with Office 365?

Can you guys recommend any services? And do you think it is necessary or should Office 365 Spam filter suffice?

Can't see why you'd need to, the 365 filtering system is particularly powerful. Even prior to going 365, we used it's filtering for our onsite Zimbra setup.

I haven't had time to really look in to it properly. Does it offer filtering by content types? i.e. inappropriate content etc.. I can't seem to find options to filter inappropriate content.. Edited May 19, 2015 by Sanm2009
