Google employed a tabbed inbox to help organize the chaos of daily email a while back, and now Microsoft has a new option for Office 365 users to get things sorted. Using its Office Graph, a feature called Clutter learns from your behavior, relationships, and preferences to show only what's important in that main repository. It sends low-priority items to another spot, keeping would-be distractions at bay. The rest? It gets stashed in a dedicated folder in the left-hand menu for easy access when you're ready. And as you might expect, Clutter's know-how syncs across the web, Outlook, and mobile devices to keep things arranged just so on all of your gadgets. The tool is turned off by default, so you'll need to toggle it on in order to take advantage. While it may not appear to be working, Microsoft says it is learning your workflow, and manually stashing less important emails will help it get a handle on your inbox a little quicker.
