Email Protection for Office 365 policies can be configured to help protect your users' mailboxes from email threats. Policies include rules and settings for:

  • spam and attachment filtering
  • managing safe and blocked senders lists
  • protecting users from malicious links in messages

Policies can be assigned to domains, distribution lists, or mailboxes.

To create a new policy, click on Add policy. Then, you will be prompted to enter a policy name and choose an existing policy to copy the settings. Once the policy name and the settings are selected, hit Add policy.

Add policy

Once the policy is added, you will be asked to add members, configure settings, and set the policy priority. You may add an email address, a distribution list, a domain, or a resource mailbox as a member of a custom policy.

Email Protection for Office 365 allows synchronizing new objects between the Office 365 admin panel to the HostPilot. After a new mailbox, distribution list, or domain is created in Microsoft 365 organization it appears in the Email Protection module after a very low propagation time.

It is possible to force the synchronization of newly created objects:

1. Please navigate to Services > Office 365 > Email Protection.

2. Click Update Mailboxes under "If the number of mailboxes differs from what you expect you can update mailboxes"


3. Refresh the page in 5 minutes to check if the number of protected mailboxes increased.

Note: Distribution list in Office 365 panel called Distribution Group, while in the HostPilot it will be displayed as a Distribution list. Also, the unlicensed user and mailbox will not synchronize to be added as a member of the custom policy.

When you add a distribution list as a member of the customs policy, the policy will be applied to all emails sent to that distribution list. If an email is sent directly to a member of the distribution list, the custom filtering policy will not be applied.


Email Protection for Office 365 allows you to set a policy priority. If multiple policies apply to a mailbox, the policy with the highest priority will be applied. The highest priority has the lowest number.

To change the priority order, simply select the policy and use the drag-and-drop feature to move it.


Note: a maximum of 50 policies is allowed. In order to create a new policy, you must first delete an existing one.
