We typically stick to MS defaults. Why do we have to enable this? This suggests some sort of risk? What is that risk. I do wish this document gave both the pros and cons to early enablement. Also someone in the comments said "The Loop App is free during public preview. Pricing and licensing requirements for the Loop App post-preview are yet to be determined.". This made me slam into a brick wall. We aren't playing this game. We already pay for E5, we boycott any add on skus above that (and I hope other admins do the same). Is the reason you have to turn this on is the fact you're planning on being greedy trolls again by addicting users then slamming us admins with having to go to management for even more money even though Microsoft is already the single greatest vendor we pay? As a 20 year admin of Microsoft technology, its never been harder to love ya. So yeah, what a roller coaster this morning, excitement to turn it on, followed by, disappointment that I can't due to not knowing if this will be included in the E5 suite.
