In recent weeks, OIT has received several calls about important email messages or deadlines that have been missed because emails have been sorted into the Clutter folder.
Clutter is a feature in Office 365 designed to move lower priority messages out of your Inbox and into your Clutter folder, saving you time when you scan for important messages. Clutter looks at how you’ve handled similar message in the past to determine which messages you’re most likely to ignore. It then moves those messages to a folder called Clutter. You can quickly scan the Clutter folder and move any messages that shouldn’t be there back to the inbox. Clutter will learn from this and do better next time.
By default, Clutter is enabled on all Office 365 email accounts. If you would like to disable the Clutter feature please follow the instructions in Knowledge Base article under “How do I turn off Clutter.”
You may receive a summary message in your Inbox with information about the messages moved into Clutter. This email is generated by Microsoft and is a legitimate message.
