My SBS 2003 server has an exchange mailbox that stopped receiving email yesterday. I'm not getting any alerts that I am noticing in the Event Viewer. I have tried to restart the Information Store and the Server itself but messages for the mailbox continue to accumulate in the Local Delivery Queue.
I am not receiving new messages either in Outlook or OWA. The Outlook client looks like it is connected to the server. I've even recreated the Outlook client profile but the problem persists. I don't believe anything is getting to the mailbox because emails for the box are building up in the Local Delivery Queue.
Is the only option to delete the user and recreate the User Account? Is there a way that I can diagnose the mailbox problem and possibly resolve it?
