    Symptoms: Inbound email is not marked as read by Service Desk, but an incident is still created.  A duplicate is then created when the services check the mailbox again.


    Cause: Permissions to the Windows Temp folder on the application server.


    Solution: Give the NETWORK SERVICE account (or whatever the identity account is within IIS for the app pool running your mail service) full control over the C:\Windows\Temp directory on the application server.
