Gets a pointer to an unwrapped Internet Message Access Protocol (IMAP) store object that provides access to the underlying Personal Folders file (PST) without invoking synchronization and downloading the items.
HRESULT IProxyStoreObject::UnwrapNoRef ( LPVOID *ppvObject );
Parameters
ppvObject
[out] Pointer to an IMsgStore : IMAPIProp store object that is unwrapped.
Return values
S_OK
- The call was successful and a pointer to an unwrapped interface has been returned in ppvObject.
Remarks
Without first unwrapping an IMAP store, accessing a message in the store can force a synchronization that attempts to download the entire message. Using the unwrapped store allows access to the message in its current state without triggering a download.
Because UnwrapNoRef does not increment the reference count for this new pointer to the unwrapped store object, after successfully calling UnwrapNoRef, you should call IUnknown::AddRef to maintain the reference count.
