I am receiving a lot of the following error in my event logs: Event Type: Error Event Source: Server ActiveSync Event Category: None Event ID: 3005 Date: 12/27/2007 Time: 8:38:01 AM User: DOMAIN\user.name Computer: SERVERNAME Description: Unexpected Exchange mailbox Server error: Server: [servername.domain.local] User: [user.name@example.com] HTTP status code: [409]. Verify that the Exchange mailbox Server is working correctly. I have tried method two in KB 817379. I have cleared the phone and reconfigured the account. I have verified all permissions and authentication methods in IIS. This only happens when users attempt to delete or move a message. Does anyone have an idea how to solve this? -- Dustin Cook dcook32p@htcomp.net
