MSN won't reconcile

[tamwhi]

I gave up my Palm Treo 770vw for a new Blackberry Storm. I've been told that MSN does not reconicle email like the Palm did.  Anything I read and delete on my computer from MSN does not reconcile with the Blackberry so I have to open every email twice to get rid of the unread icon on my Blackberry.  Is this true? My Palm always worked in-sync with MSN and if I deleted or read email on my computer it was automatically done on the handheld.
