Error on Reply Email

I got this error on all Reply Email

the message was not completely downloaded,so no operationcan be performedon it

I cant reply my email’s, i need close EMClient and open again…

Hi, after close and open it is possible to reply to emails?
Can you describe some simple scenario what do you do before this issue shows up? I mean how fast do you reply to emails - right after they arrive to you?

Also what version exactly do you use?
