I'm trying to use the SOAP API to retrieve attachments to calendar appointments and emails, but I'm facing some difficulties.

I succeed to retrieve the appointments using the GetItemRequest, but I cannot see when such an item has an appointment attached to it or not. Is there a way to determine that?

I'm using the searchRequest to list all the conversations in a Folder, and I would like to know if a conversation contains attachments. Is it possible to do so?

Thanks in advance,
