SYMPTOMS
The OleConvertStorageToOLESTREAM API (application programming interface) call is used to convert the storage of an embedded object from the OLE 2.0 storage model to the OLE 1.0 storage model. However, if the OLE 2.0 object has a CLSID of NULL, then OleConvertStorageToOLESTREAM fails with a return code of OLE_E_CLASS.

<div class="status_section">

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

<div class="moreinformation_section">

MORE INFORMATION
NOTE: It is unusual for an embedded object to have a CLSID of NULL. However, after IOleLink::SetSourceDisplayName has been called to change the source of an embedded link object, it is possible for that link object to have a CLSID of NULL.
