  Hi,
  
  Sorry for the delay in replying - I've just got back into the office after being distracted by Christmas related activities :-).

  The docs claim that the messages are stored “single instance†in the archive, but if you restore them to the mailbox, it loses the “single instance†storage. Does this mean an email with a very large attachment which was sent to say 1000 people would be restored, and then the email and attachment would be replicated for each of the 1000 people in Exchange?

  
  That's true... sort of. When we say "restore", that's something that you'd normally only do if you wanted to completely un-install the product, so whilst it could be painful from an increased storage point of view, it isn't something we'd hope would happen very often at all.
  
  What we don't mean when we say "restore" is just the act of viewing it (either with or without the add-ins) - doing that won't actually push the message back into Exchange at all, so you won't lose single instance in that situation.
  

  Once a message is in the archive, it (apparently) can never be deleted from it. That could be problematic. What solutions are you working on to enable permanent removal from the archive, per email or range/person?

  
  Whilst you can't currently remove individual messages from the archive, you can retire archive stores - so, for example, you could create a new archive store every quarter, and only keep the last x years' stores on-line. Anything older than that can be taken off on to tape or similar long term storage, just in case someone did need to access a very old message.
  

  What happens if the user deletes the message from Exchange? Is it still I the archive and just inaccessible because the stub is gone? Does that mean the archive will grow forever?

  
  It's still accessible - the User Archive Access Service provides an archive search facility, so users can still locate and retrieve archived messages even if they've deleted the stubs from Exchange. Likewise, the search provided by the Outlook add-in can also find messages for which the stub has been deleted.
  

  Also, what is the performance of the system since it uses MAPI instead of some agent on the Exchange server?

  
  We've not got any formal benchmark figures yet, but the testing we've done so far indicates it's similar to the performance of most of the other tools out there. Hopefully we'll be able to give more details as we get closer to release.
  
  I hope that helps - let me know if you've got any other questions.
  
  Regards,
  Robert
