How to manage spam decentrally with Office 365 / End-user spam notification

Today I put again some effort into researching the topic of spam management.
Office 365 offers a number of configuration options that can be controlled in the Office 365 "Security & Compliance Centre".
This is mainly done via policies.

The following are the policies that are always present by default.

Personally, I was only concerned with the first policy the "Anti-spam inbound policy".

Actually, I blogged about it once before.

In this case, I have established a country-specific filtering.

At this point, however, I would like to address a topic with which one can shift the administrative effort somewhat, i.e. delegate it back to the user.

The issue I would like to address is the end-user spam notifications.

How to enable:

• Open the Security and Compliance Center, navigate to Threat management > Policy > Anti-spam or use the direct link https://protection.office.com/antispam.
• Open the Anti-spam inbound policy (Default)

• Look for "Send end-user spam notifications every (days)" and the "Edit actions" link that follows.

• "Enable end-user spam notifications" - Select this check box
• "Send end-user spam notifications every (days)" -  Specify how often to send end-user spam notifications. The default is 3 days. You can specify between 1 and 15 days. I prefer to do this on a daily basis.
