New Post: MAPI Spooler Status returns STATUS_FAILURE

After executing the "Session\Logon" command of MFCMAPI and supplying a correct password, I receive the correct table of MsgStore providers in the main screen. Then I execute the "Session\Advanced logon\View status table..." command. When I do so, the "MAPI 1.0 Spooler" returns a status code of 4, "STATUS_FAILURE". Outlook appears to be able to transfer mail with the profile, so I assume the spooler must somehow work. Have I missed some important configuration step? Thanks in advance for any help that you can provide.
