@Peri Rocha I know that downloading them via the portal would be stupid but the set you linked is out of dates and it doesn't contain the icons currently used in the portal :)

@Tomasz Wiśniewski you can typically find a collection of icons available for download here: https://www.microsoft.com/en-us/download/details.aspx?id=41937. It's not on our immediate plans to make them available specifically through the Azure Portal. Hope that helps. Peri

When will the icons be downloadable? 

Great updates ! thanks for the detailed information. It helps a lot. 

  Thanks for update
