I'm using office 365 for business. A couple of weeks ago I got an email introducing the new "clutter" feature with a "click here to configure" button saying that if I didn't do anything, the feature would not be enabled. I deleted the email and the new clutter folder thinking that was the end of the matter.

Yesterday I got another email, again introducing the clutter feature, this time telling me it was already enabled. Sure enough, the clutter folder had reappeared and some emails were in it. I followed the instructions to go to the options screen (https://outlook.office365.com/owa/#path=/options/clutter) to disable it, but found that the feature is already set to disabled.

Anyone know how I can actually turn it off?

Options -> MAIL -> Clutter -> Don’t separate items identified as clutter:

enter image description here

Update: You may also want to enable it first and then disable again if it is disabled already.

Or using PowerShell (if you have access):

Get-Mailbox | ?{-not (Get-Clutter -Identity $_.Alias).IsEnabled} | %{Set-Clutter -Identity $_.Alias -Enable $false}

    yup, that's the screen I've linked to above. it already said "Don’t separate items identified as clutter"

  • And it still moves messages to Clutter? If so, try to enable it first and then disable again.

    5 days later and I haven't had any more in the clutter folder, so enabling and disabling it seems to have worked. Exactly the same thing happened to a colleague of mine, so it wasn't a one-off, but not sure whether this problem affected all office-365 users or just a few.

  • Thanks for the follow-up! I've just updated the answer to reflect this case.

Here is one work-around for this, for admin's sake: https://community.office365.com/en-us/f/148/t/352806

Hi Kellan,

Administrators are able to disable clutter via PowerShell cmdlet. To disable clutter for all users in your organization, please follow the steps below:

  1. Connect to Exchange Online using PowerShell.
  2. Run the cmdlet below:

Get-mailbox -ResultSize Unlimited | Set-Clutter -Enable $false

However, end users can also enable it by themselves, so administrators cannot prevent them from using it.

I will pass your requests on to our relevant team. At the same time, I suggest you submit your advice to our feedback team. Customers’ feedback will help better our products and services. I hope the Clutter can be controlled completely by administrator in the future.

Your understanding is highly appreciated.

Regards, Toby
