HELP!  Please!!

I have Windows Live Mail (& Essentials) installed on my laptop and desktop for work.  I have one email account.  I have set up the one (& same) email account on both computers, and always log into my Microsoft account on both computers.  However, the 'Folders' I my Live Mail are not syncing.  For instance, if I send an email from my laptop, and then later go on the desktop & look under the 'Sent' folder, the email I sent from my laptop does not appear in the 'Sent' folder on my desktop.  If I delete emails on either computer, I have to do it on both. 

Essentially, I am looking to log into my email, and have a mirrored image/storage/account on both computers.  How do I do this??!

(Note:  I have already uninstalled and reinstalled both Essentials and Windows Live Mail on both computers, and deleted and readded my email account on both computers...)

THANK YOU SO MUCH!!!!
