Refresh the apt cache:
sudo apt-get update
Check for installed SSTP:
sudo apt-cache search sstp
Install needed packages:

Create a new VPN connection by choosing newly added SSTP connection type.
Install Remmia (RDP client) to your Ubuntu and create connection to the desired host inside the office VPN.
All you need to view your workplace is to run the VPN connection and after that the Remmia RDP session.
