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 distraction 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 thing 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 its learning your workflow, and manually stashing less important emails will help it pick get a handle on your inbox a little quicker.
