Who cannot see these BES users' correct Free-Busy info?
Exchange 2007 user, or Excahgne 2003 users, or both?
I would expect that it would be only 2003 users or both. It's really just a guess. I am not sure how exactly Exchange 2003 users should see Exchange 2007 users' info.
Or how a user in one Administrative group should see the info for another user in a different Administrative group.
I'll see if I can find anything online. Don't hold your breath though :(
Just to throw it out there, is there a replication going on between these Public Folders?
Again, I am not an Exchagne Admin, so I don't know that much about exactly how Exchange does FreeBusy data. I am much better with BB/BES than Exchange :P
Here is someone else that sounds like they had the same issue without BES:
