Hello, I've installed AAA to run on my Exchange server as a local service. I have also configured the exception in the Internet Options to allow the exchange server and confirmed that WebDAV is enabled. When I run "D:\Program Files\Exchsrvr\Agents\AutoAccept>cscript RegisterMailbox.vbs /m:chris.room@anglicare.org.au /debug" it appears to work fine but running ListMailboxes, I see nothing and running MailBoxstatus.vbs I see Registration Status 2.

Found the cause... I thought I should start the AAA service but in doing so it appears to of caused this problem. Stopping the service and re-registering the mailbox fixed it.
