We have problems retrieving some archived items with createItemRequest. The items have been archived and then purged.
The createItemResponse.status is 0 (success) but createItemResponse.id is not returned.

It takes some tries to be reproduced. We did this with "Reminder Notes" sent to the mailbox owner himself and CC to somebody else. So we have 2 Notes in the originating mailbox. One displayed in "Sent Items", one in "Calendar". Both are stored in "Calendar".
After that: archive, purge, createItemRequest.

This one works.

This one does not work. There only minor differences in the XML.

Unfortunately there is no error code returned from GroupWise. How can we find out what happened here?
