I have a half dozen or so Blackberry users. We have an Exchange 2003 server and Outlook 2003 on the workstations, using BIS for email (no BES). The Blackberries are set up to reconcile mailbox & handheld. If they delete something in Outlook, it does not delete on the BB. However, if they delete a message on the BB, it does delete in Outlook. They are not running cached exchange mode, and messages are still stored in "deleted items" (it's not set to empty automatically). There are no rules or agents in Outlook. I'm trying to figure out why delete sync works one way but not the other. Thanks for any assistance!
