Microsoft's FindTime service helps Office 365 users find the right time to schedule a meeting with people inside and outside their tenant. It's an underappreciated gem. And the good news is that an even better service called Calendar.Help is on the way. Well, it's better if you like asking Cortana to find the right meeting dates for you rather than the more-hands on approach taken by FindTime. Whichever way you cut it, help is always appreciated when setting up meetings, so it's nice that these tools are available.
