Is there a way to show the current connection status on the email client, for example a green icon when all is working and red when there is no connection issue. I disconnected my internet and nothing showed that the client cannot connect. This is very important when waiting for email, swapping between connection, etc.
If eM Client is not able to connect to your email server, there will be a red warning chevron displayed next to that account. Hovering over that chevron will give you the error.
