How to cancel a " Sending " task?

I m using the latest version of eM Client. In case I click " Send " accidentally, I see no way to cancel sending task. I even see no Outbox so that I delete message from there!

well, no answer means there is no way to cancel a task in eM Client :frowning:

Hello,
I am sorry, but it is not possible. The only possibility is to force eM Client to offline mode, but you should be very fast.
