(The dupe yesterday turns out to be because L(3) had routing 'issues' in Tampa yesterday afternoon when I was emoting...)
So the next question is "zimbra-archiving is optional to install, defaulting to no. Do you want it anyway?"
And the unknowable answer to that question -- unknowable to me, at least -- is "if I install it to try it out during my trial period, and decide it's not worth the extra $24 a seat, how does it degrade when I go to a regular paid license that doesn't include it?"
Anybody? Anybody? Bueller??
A related question, pertinent to my situation is: "If I initially have to license the Outlook connector because I can't immediately wean all my executives off it to the webclient, what happens when I finally do?"
