I tried to set up Live Mail on a Windows 7 computer so that it synched with my Hotmail account and it worked flawlessly.  I removed my account and then tried to add my wife's Hotmail account and it returns error codes 3219 and 0x8DE00005.  After trying the various permutations, my Hotmail synchs whether or not hers is included and hers gives that error message whether or not mine is included.  I restarted the computer between modifications and the problem persisted.
