I posted a message a while ago (http://www.scalix.com/community/viewtopic.php?t=4577) asking if this is true that Scalix shares address book across all domains, and Florian confirmed that it is true.
We had to stop right there and switch to a different Collaboration Server, although we liked Scalix.
Few days ago I was contacted by someone from Scalix asking me if we want to use Scalix. I explained to him that why we decided not to use it. He got back to me the next day telling me that this issue is no longer part of the new Scalix 11 GA.
Meaning, Scalix 11 GA allows isolated address books for every user or at least every domain. Is this true?
