Parameters

lhSession

[in] Session handle that represents a valid Simple MAPI session. The value of the lhSession parameter must represent a valid session; it cannot be zero.

ulUIParam

[in] Parent window handle or zero, indicating that if a dialog box is displayed, it is application modal. If the ulUIParam parameter contains a parent window handle, it is of type HWND (cast to a ULONG). If no dialog box is displayed during the call, ulUIParam is ignored.

lpszMessageID

MAPI_E_INVALID_MESSAGE

An invalid message identifier was passed in the lpszMessageID parameter. No message was deleted.

MAPI_E_INVALID_SESSION

SUCCESS_SUCCESS

Remarks

To find the message to be deleted, call the MAPIFindNext1YL.6BX function before calling the MAPIDeleteMail function. Because message identifiers are opaque, messaging system-specific, and can be invalidated at any time, MAPIDeleteMail considers a message identifier to be valid only for the current session. MAPIDeleteMail handles invalid message identifiers by returning the MAPI_E_INVALID_MESSAGE value.
