I am running BES express on a server 2008 server. receiving and sending email sync from OUtlook to the Blackberries works fine.
when I delete from the handheld it deletes from Outlook but when I delete from outlook it does not delete from handheld.
I have resent the service book from the BES.
From the device email reconciliation:
Delete on Mailbox and handheld
wireless reconcile ON
on conflicts: Mailbox Wins.
