We try to read the content for all objects in a folder. To do that, we use createCursorRequest and readCursorRequest to get a List of object IDs and then
HTTP GET /attachment?session=...&id=...
to stream the content for those IDs. This works fine for objects with type Mail, but the Groupwise POA drops the connection without sending an answer for objects with type DocumentRef. In our case these are office documents moved into the groupwise folder with drag&drop.
Is there any way to read the content of those objects via SOAP?

Groupwise POA version: 12.0.2
Schema version : 1.04
