We have recently migrated our email to Office 365. I just received an email with the subject "Let's clean up" with the body below
Let's clean up
It looks like your mailbox is cluttered. In the past week, you received xxx items you're likely to ignore.
If you'd prefer not to see that clutter in the future, go here to turn on Clutter.
Clutter places these items into their own folder, helping you focus on your most important messages. If Clutter gets it wrong, you can move messages and conversations back into the inbox, and vice versa. And Clutter will learn from its mistakes. If you have questions, go here.
Say hello to a cleaner inbox.
This system notification isn't an email message and you can't reply to it.
It is my understanding that I can set up a rule to limit some email from the clutter filter but I (as an administrator) cannot stop or start this feature. Please correct me if I am wrong.
For now, we do not want this email going out to users. Does anyone know if there is a way to control this email from going to staff?
Can I put a rule to redirect it or delete it?
Is there a setting to disable this email?
