I am trying to tweak a blackberry server and have been advised I need to make some registry mods. It tells me that I need to change the MSExchange ADAccess registry item, but it does not exist. I am running Exchange 2000 on a windows 2000 server. Is this key new in Exc 2007?

You are correct, this is an E2K7 Registry key. Is there an E2K/E2K3 equivilent to the advice you have been giving (or are reading.). Or, if you could share with us what you are trying to accomplish we might be able to help you figure out the rightkey.
