Change sender email address

Hello,

when I click on an emaillink (link mailto:) - then emClient creates an Email with my standard - account. 
But I have more then one account - how can I quickly change the sender-address?

It should be like this:

It is just like that. There is a pull-down arrow next to your email address . You can select any email address you like, just as you show on your Ubuntu example.

Thank you!  Now I have found the Arrow - BUT: see the Screenshot  - ther was no arrow, because the window was to small :slight_smile:

On my Surface 4 it won’t let me make the window small enough to hide arroe.
