My problem is that I'm receiving emails from my msn email account on my blackberry, but when I delete the messages on my computer, they do not automatically delete on my phone. I recently upgraded the OS on my phone and ever since then, this scenario has been happening. I have checked my reconciliation options and everything seems to be in order. Any suggestions? Thanks.

Windows Live/MSN does not have full 2-way sync capabilities with BlackBerry. Microsoft is slow to update like Google with GMail, which syncs much better. I personally believe Microsoft has no intention of offering full integration with anything but WP7.

It worked fine until I did the recent OS upgrade. Whenever I deleted emails on my PC, they would also be deleted from my phone and vice versa. Not sure why it just stopped all of a sudden.
