How can I get rid off the avatar pics?

Hi at all,
Ihm on Client version 9.0.1632. and I wonder how I can disable the avatar pics. It should be possible by right clicking on the top of the mail list and disable “show avatars”:


but there is no correspondenting option in my client:


Is this a Pro feature?
How can I disable the avatars?

Thx and brgds

Right-click blank area of horizontal columns line, click “Columns Configuration”, highlight “Avatar” and click “Remove”

That worked perfect. Thx :slight_smile:
