ADD ECAL

First things first, any licensing advice you receive from someone on a bulletin board is that person's opinion only. It won't stand up in a licensing audit or court of law, so you are always best to check what you hear with MS direct.

With that out the way, you don't need to tell Exchange about any CAL packages. CALs in Microsoft's latest products (Terminal Server Licensing not withstanding) are an honour system. You need to have the physical licensing filed in the event of an audit, but the server itself doesn't track the CAL licenses. It won't stop working if you don't have enough; you would simply be breaking the licensing terms with all the legal repercussions which may follow.

Thanks for your response! I understand that I can still use the archives without entering the ECAL, but I was worried that there would be a certificate error or something along those lines the users would see.
