For Live / Hotmail / MSN the following worked for me. Just turn off Sense, finish the run through to sign in and then Sense back on.

(As a note sometimes, your phone may freeze while re-activating Sense, just soft reset then re-activate when the phone boots up and Windows Live will be fine) You can then go into the windows live settings and setup accordingly. I always used the As Mail Arrives option (Push-email) and it worked flawlessly! Hope this helps everyone having troubles!
