Error notification supress

I am running eM Client on a computer which looses connection to Exchange server few times per hour due to a VPN tunnel problem. I have frequent error notification pop-up stating that connection with server is lost. Users are puzzled with the message, and I would like to switch it off. I suppose that incomming mail would come and outgoing mail would go as soon as connection is back.

Is there a way to switch to a more discrete notification when client goes on-line and off-line, like known in Outlook 2010 or 2013 (in status bar only)?

Hello Ivo,
in Menu>Tools>Settings>General>General section there is Operations window ´╗┐setting.
Uncheck the Show window when an error occurrs option.
