Office365 users may have encountered a unique folder in their mailbox.
It's called the Clutter folder, and I'll give you a quick, un-cluttered break-down.
I'm sure you know what the Junk folder is and how it catches all of the e-mails you don't want to see. Well a byproduct of this is that it helps you get to what's important without having to wade through all of the garbage.
Clutter is similar, but imagine it on a higher tier as it attempts to catch the e-mails of less importance. It moves your low priority messages out of your Inbox so you can easily scan for important messages. These could be items you may want to read, but are not deemed important; such as newsletters or marketing periodicals.
The cool part is that Outlook will already have a pretty good idea about what these items look like. However if you see an item in your Clutter folder that shouldn't be, it's as easy as throwing it back in your inbox and Outlook will remember not to filter e-mails from that sender anymore. It analyzes your email habits, and based on your past behavior, it determines the messages that you’re most likely to ignore.Just as easily, items can be auto-filtered to your Clutter folder by sending one there.
Microsoft knows that not all changes are welcome by every user. The Clutter folder is an option that can be turned off. If you are certain you'd like it turned off.
This is one of many features in Outlook that can help productivity,
