We upgraded to exchange 2010 from exchange 2003. &nbsp;About 95% of out users use outlook 2003. &nbsp;The issue we are having is when we try to move or delete emails rather one at a time or several at once, there is a delay. &nbsp;The message will still show in the mailbox folder after you delete or move the message and will continue to show there until you select a different folder or close out of outlook and open it back up. &nbsp;One change that I made was checking the check box for Encrypt data between Microsoft Office Outlook and Microsoft Exchange Server under exchange server settings\ security Tab. &nbsp;Is there anything else thats needs checked or unchecked?
