I have a one.com webmail account which I have just started to use through Windows Live Mail. I love it except..

Whenever I send an email, I need the sent email to save on my one.com webmail server, so I can still access these sent emails through my phone and another user has access on his phone also so he needs to see what is being sent

I do not want the sent item to only be viewable on my windows live mail

Can someone help me, I believe it is a simple thing to figure out but I don't know where to go!

Thank you
