IMsgStore::Unadvise

The IMsgStore::Unadvise method cancels the sending of notifications previously set up with a call to the IMsgStore::Advise method.

Quick Info

See IMsgStore : IMAPIProp.

HRESULT Unadvise(
  ULONG ulConnection  
);

Parameters

ulConnection: [in] Connection number associated with an active notification registration. The value of ulConnection must have been returned by a previous call to IMsgStore::Advise.

Return Value

S_OK: The registration was successfully canceled.

Remarks

The IMsgStore::Unadvise method cancels a registration for notification. Unadvise releases its pointer to the caller's advise sink, which it received in the Advise call used for registration.

Generally, Unadvise calls the advise sink's IUnknown::Release method during the Unadvise call, but if another thread is in the process of calling the advise sink's IMAPIAdviseSink::OnNotify method, the Release call is delayed until the OnNotify method returns.
