Clutter in Office 365

Clutter is a feature in Office 365 that helps you focus on the email messages that are most important to you. Clutter moves unnecessary messages from your Inbox so you can easily scan for the messages that need your attention. Clutter learns from the user’s email habits and gets better over time at figuring out what messages they’re going to ignore. Moreover, you can control whether Clutter is turned on or off for your account, and you can always move a message back to your Inbox if Clutter misclassified it.

If you find that Clutter isn’t moving any emails, or if it’s not moving the types of emails you want it to, there are a few things you can do to improve its performance. First, make sure that Clutter is turned on for your account. You can do this by going to the Clutter page in Office 365 settings. Next, take a look at your email habits and see if there are any patterns that Clutter isn’t picking upon. For example, if you always delete messages from certain senders without reading them, Clutter might not realize that these messages are a low priority for you.

But as some users rely on rules for managing the mails, this Clutter feature is unnecessary for them. Also, users who complain about not finding the emails crucial for them in their Inbox can check for the emails in Clutter. So, they can consider disabling this feature.

Here we are discussing two ways for disabling the Clutter feature, one for administrators and the other for end users.
