Updated June 20, 2023: The rollout for handling intra-organizational messages that contain a malicious URL in Microsoft Defender for Office 365 is complete. <\/p>\n

We are updating the handling of intra-organizational messages that contain a malicious URL in Microsoft Defender for Office 365. <\/p>\n

[When this will happen:] <\/p>\n

Rollout will begin in early June and is expected to be complete by mid-June.<\/p>\n

[How this will affect your organization:]<\/p>\n

Admins will have at least 30 days to opt out of how intra-organizational malicious messages are handled within the anti-spam policy. Admins will also have the opportunity to define handle intra-organizational messages containing malicious or spam-based URLs are handled in their tenant.<\/p>\n

Once this rollout is completed, Admins will be able to define how they want to handle malicious or spam-based URLs detected in intra-organizational messages. The initial default behavior will be to take no action on these messages, but the detection will be recorded as it is today. After the opt-out period no less than 30 days, the default behavior will be to quarantine messages that contain high confidence phishing URLs.<\/p>\n

If you want to opt-out or opt-in early you can adjust your preferences within the anti-spam policy, more information can be found in Configure spam filter policies<\/a>. If you do nothing, the policy will default to act on messages containing high confidence phishing URLs once the opt out period ends.<\/p>\n

[What you need to do to prepare:]<\/p>\n

You don’t need to do anything, however, if you don’t want to act on intra-organizational messages, you can opt-out by changing the Anti-spam setting to NONE. If you prefer to opt-in to the new behavior now, you can select High Confidence Phishing or one of the other options from the drop down.<\/p>\n<\/td>\n<\/tr>\n
