Otevření aplikace do stavového řádku

Hello, is it possible to set the application so that it opens in the status bar when the OS starts, which I have set? I have not found such functionality anywhere. Thank you

Using Windows you can set eM Client to automatically start minimised on the taskbar. See the following page thread.

Using a Mac, just open eM Client and minimise it. Then when you shutdown, tick the box to automatically start open apps on OS popup box.
