The calendar sync seems to be a generalised issue in our enterprise.
I am affraid that every users (45) are experimenting the same problem. All emails are correctly redirected to the blackberry and other handheld devices features seems to work with no reported issues.
We just finished rebuilding our Microsoft Exchange enterprise server 2003 on new hardware.
The problem occured before the migration process was even started.
RECAPITULATION OF THE PROBLEM :
-When creating new appointements from blackberry device, it will NOT show up in the outlook 2007/2003 calendars.
-When creating appointment from outlook 2007/2003 calendars, it WILL show up on the blackbery device.
