As Golum would say, "We hates it!". We've tried the Office 365 and not a single one of our test users liked the interface. When are you going to update the POS interface so it doesn't cause our employees to want to rip their eyeballs out? From an administrative side, the DirSync tool looks like some high-school student wrote it. You've got parts of it in the DirSync, parts of it in PowerShell, parts of it in the MSOL PowerShell, and parts of it in the EAC. Good lord, it looks like it's been hacked together as some kind of Alpha test. I was floored when I realized this is actually the correct way to DirSync. Very poor job with the whole Office 365 offering. WFW 3.11 did a better job.
