Hotmail SENT messages sent from BB not showing up when veiwing account on desktop

My Blackberry Hotmail accounts have been working fine for years until... This problem just started 2 days ago.

When I send an email on my Blackberry device (BIS), the email does not show at all under SENT when I veiw my Hotmail account on my desktop.

Note: When I send an email (Hotmail) on my desktop, it DOES show the sent message under SENT.

I've deleted the accounts on my Blackberry and then re-esablished... But still does not push the sent messages that are originated on my Blackberry to desktop.

PLUS: I've done many test send messages from my BB to myself, and receipt on the BB is extremly slow (but instant receipt on desktop).

Did you ever figure out how to remedy this? The same thing started happening to me just a couple days ago.
