IMAPISession::Logoff

Office 2007

Ends a MAPI session.

HRESULT Logoff(
  ULONG_PTR ulUIParam,
  ULONG ulFlags,
  ULONG ulReserved
);

ulUIParam: [in] A handle to the parent window of any dialog boxes or windows to be displayed. This parameter is ignored if the MAPI_LOGOFF_UI flag is not set.

ulFlags

[in] A bitmask of flags that control the logoff operation. The following flags can be set:

MAPI_LOGOFF_SHARED: If this session is shared, all clients that logged on by using the shared session should be notified of the logoff in progress. The clients should log off. Any client that is using the shared session can set this flag. MAPI_LOGOFF_SHARED is ignored if the current session is not shared.

MAPI_LOGOFF_UI: Logoff can display a dialog box during the operation, possibly prompting the user for confirmation.

The IMAPISession::Logoff method ends a MAPI session. When Logoff returns, none of the methods except for IUnknown::Release can be called.

When Logoff returns, release the session object by calling its IUnknown::Release method.
