Remarks
Sub-object restrictions are not supported by all tables. Typically, only folder contents tables and search results folders support them. For example, sub-object restrictions are used to find a message that has a particular type of attachment or recipient.
If an implementation does not support sub-object restrictions, it returns MAPI_E_TOO_COMPLEX from its IMAPITable::Restrict or IMAPITable::FindRow methods.
