Why don't I have sound notifications when receiving new emails on my Nokia Lumia 950?

No sound notification when receiving new emails on nokia lumia 950

I have 2 email accounts, one being an exchange based and another MS outlook live account. I've sent them up properly but am not getting any sound notification when I receive new emails. I've checked ALL settings and everything is right, so I'm not sure what else I need to do to make sound upon receiving new emails happen.
