How to turn on Junk email filtering in OWA 2013
If spam emails are being delivered to your inbox instead of your junk email folder, you should check if junk email filtering is enabled in OWA. This guide explains how to do just that.
You must have a hosted Exchange 2013 account with Sherweb.

2) Click on the Options gear and then click on Options.
3) Click on block or allow. Make sure the Automatically filter junk email radio button is selected.
4) Click on Save.
