VML support in Outlook on different platforms

Copper Contributor

Is there any official guide as to which versions of Outlook still support VML tags and on which operating systems?


VML tags are a commonly used technique to get rounded buttons or backgrounds to work in Outlook HTML.


The latest desktop version of Outlook running on Windows 10 supports VML tags (as described here: https://backgrounds.cm), however, Outlook running on iOS and on some surface devices seems to not support VML?
