If like myself, you are becoming tired of the Microsoft adverts within current versions of Skype, copy/paste this into your Mikrotik Router’s CLI (if it is providing you with your DNS Service).
/ip dns static
add address=127.0.0.1 name=ad-emea.doubleclick.net
add address=127.0.0.1 name=ads2.msads.net
add address=127.0.0.1 name=msntest.serving-sys.com

Microsoft are bound to add more of these advertising services and thus keep adding more and different service providers so at some point adverts will return, but for the moment, it seems to make a big difference to my experience as I am no longer getting any adverts at all while using Skype. 🙂
Luckily I don’t seem to get ads have you tried disabling promotions in the settings?
It’s in Options > Notifications > Alerts&Messages > Promotions
