The positives first. Azure AD can be used to log into my work laptop from any network, while still providing the security of or domain. It works seamlessly with Windows 10, which is great. Our only issue came from trying to roll it out slowly. It just showed up on some of our computers, leaving some of our employees to freak out, because they weren't set up on Azure yet and couldn't log in without changing the domain.

Like I said above, sometimes it attaches itself to devices on the domain that weren't ready for it, which causes a panic when people can't log in. Review collected by and hosted on G2.com.
