if I have not replied to you then no.
Start a new convo as if you reply to an old msg from the old system it don't start a new convo, it will send me an email to say I have msg but then its not in there, your not the only one it happens to, if im on the ball the day I get the email I start a new one but if im busy I will forget.
Try it and see what happens.
