Exception while getting Rec ipientStatusList of Incoming Messages

Hello,

while accessing the RecipientStatusList via the Groupwise Object API of
Groupwise 8 (German Version), logged into the Groupwise Object store as
a trusted application, we have experienced the following: When accessing
the List of Outgoing messages, everything goes smoothly, but when trying
to access the RecipientStatusList of Incoming messages, we get a
COMException saying ""aktualirierungszugriff für den aktuellen Nutzer
wurde verweigert", which probably roughly translates to "Access denied
for current user."

Is this intended behavior or are we doing something wrong?

Best regards, Martin Schmidt.
