If the answer is yes, you will love this Microsoft feature!
Clutter is an email filtering option available to Office 365 users. Similar to an anti-spam filter, it moves low priority emails (determined based on your reading habits) into a ‘Clutter’ folder where they can be reviewed later or simply ignored.
The feature was enabled by Microsoft for all Office 365 accounts in June 2015. Individuals can choose to disable it by logging into Outlook Web Access (OWA): Click on the Gear, Options, Automatic Processing, Clutter and select Don’t separate items identified as Clutter then click Save.
Users can drag messages they deem suitable to the Clutter folder to “train” the tool to spot similar email in the future. The tool gets smarter over time, learning from your prior actions with similar messages.
Once Clutter is enabled in OWA, it appears in other clients linked to that Exchange account, including Outlook on both Windows and OS X desktops and notebooks, and the iPhone and Android OWA apps.
