Microsoft will be retiring the Clutter feature from Outlook starting on January 31st 2020. Instead, they are using the Focused Inbox experience to help users manage their email which they say (and we agree) provides a much better benefit than Clutter, showing the less important email in “Other”.
The closing down of Clutter affects all platforms, so that is Outlook Web App, Outlook Desktop and Outlook Mobile.
What’s the impact
Not much really. Microsoft have said they will make Clutter available to Office 365 users until January 31st 2020 but to prepare for Clutter’s closing, they have switched off the Clutter feature by default for new users.
It’s also deactivated for those users with extremely low mailflow usage (less than 12 emails moved to the Clutter folder monthly), however it can be re-enabled at any time (not sure why you would want to).
How to prepare for the change
If your company is using Clutter today, the process to move to the Focused Inbox does depend on what version of Outlook Desktop you are using. However much of it is automated with visible switch buttons within the Web and Mobile Outlook platforms.
