Microsoft will be retiring the Clutter feature from Outlook beginning January 31, 2020. To help the users manage their mail and be productive, they are leading with the Focused Inbox experience which provides a similar benefit as Clutter by showing less important and urgent mail in Other.
Microsoft will continue to make Clutter available to Office 365 customers until January 31, 2020. To prepare for Clutter’s eventual retirement, they’ve turned the feature off by default for new users. It’s also deactivated for those with extremely low usage (less than 12 emails per month being moved to the Clutter folder), however, they can re-enable Clutter at any time, if desired.
If your organization is using Clutter today, the process for transitioning to Focused Inbox depends on what version of Outlook you are using.
