I found how to get rid of Ads in email box, please read below
Go to http://winhelp2002.mvps.org/hosts.htm and follow instructions.
This will also block a lot of the banner ads and other ads. Good luck
Will try this on my home computer but unfortunately cannot do anything on the work one as we run from a server - will talk to our IT guys about it though. Can you also do this on your tablet?
