Motorola Droid 4 :: Incoming Messages Sync Correctly But Messages Delete On The Phone Do Not Delete From The Server?

I recently upgraded from the D1 to the D4 and have my Hotmail account set up via Corporate Sync. Incoming messages sync correctly but messages I delete on the phone do not delete from the server. On the D1 the two-way sync worked correctly for emails deleted on the phone but I can't seem to get it to work on the D4.My settings for the corporate sync account are:Username: full @hotmail email addressPassword: passwordServer: m.hotmail.comUse secure connection: yesProxy: blankAnyone else having this problem? Is there a fix?
