I was curious if anyone could tell me where I can find the system administrator manual for v12 SP3? I've looked through the 'docs and FAQ' and although it covers many things it lacks the details I want on most subjects. I assume there is a manual that covers each feature, how it works and how to set it up somewhere? With the service pack releases coming out so quickly I'm having a hard time keeping up with the new features, what changes were made, what new buttons are available (which ones are gone), how those work, etc... for instance I'm currently trying to find out what happens when you enable 'holiday hours'... I can't find anything describing what this does - does it act like an automated attendant? Is it just a message?? Does it override everything??? I could go on but I think you get the idea... thanks!
