Microsoft anti phishing free

You can't remove the default anti-phishing policy. As previously described, an anti-phishing policy consists of an anti-phish policy and an anti-phish rule. In Exchange Online PowerShell, the difference between anti-phish policies and anti-phish rules is apparent. You can create a new anti-phish rule and assign an existing, unassociated anti-phish policy to it. An anti-phish rule can't be associated with more than one anti-phish policy. You can configure the following settings on new anti-phish policies in PowerShell that aren't available in the Microsoft Defender portal until after you create the policy:.

To enable or disable existing anti-phish rules, see the next section. Otherwise, the same settings are available when you create a rule as described in the Step 2: Use PowerShell to create an anti-phish rule section earlier in this article.

You can't enable or disable the default anti-phishing policy it's always applied to all recipients. The highest priority value you can set on a rule is 0. The lowest value you can set depends on the number of rules.

For example, if you have five rules, you can use the priority values 0 through 4. Changing the priority of an existing rule can have a cascading effect on other rules. For example, if you have five custom rules priorities 0 through 4 , and you change the priority of a rule to 2, the existing rule with priority 2 is changed to priority 3, and the rule with priority 3 is changed to priority 4.

The message or the attachment asks you to enable macros, adjust security settings, or install applications. Normal emails won't ask you to do this.

The message contains errors. Legitimate corporate messages are less likely to have typographic or grammatical errors or contain wrong information.

The sender address doesn't match the signature on the message itself. For example, an email is purported to be from Mary of Contoso Corp, but the sender address is john example. Corporate messages are normally sent directly to individual recipients. The greeting on the message itself doesn't personally address you.
