Thank you for your enquiry.
Unfortunately we do not have a an immediate fix or automated workaround for this problem. In fact, the problem occurs when using the GroupWise Object API to select a message in a shared folder that was created by another user; there is no problem selecting a message in a shared folder which you own.
We are very busy with several projects just now, and we expect to look at this issue in early June, 2004. As soon as we have more information we will post it to this thread.
