If you are running ads in the EEA, UK, or Switzerland, the clock is officially ticking.
Microsoft has announced it will start enforcing Consent Mode.
Just like Google’s shift earlier this year, Microsoft is moving toward a “consent-by-default” framework. If you haven’t implemented a valid consent signal by the deadline, the consequences for your campaigns are real:

📉 Loss of Conversion Tracking: Microsoft will stop processing UET-based conversions.
👥 Audience Stagnation: Your remarketing lists will stop populating.
🤖 Algorithm Impact: Without data, automated bidding and Performance Max campaigns lose the “fuel” they need to optimize.
The “Why”:

This isn’t just Microsoft being difficult; it’s a direct response to the Digital Markets Act (DMA) and the evolving privacy landscape in Europe. The goal is to ensure that device identifiers (cookies) are only dropped when a user has given explicit permission.

The “How” (3 ways to stay compliant):
Direct Integration: Manually update your UET (Universal Event Tracking) tags to include consent parameters.
CMP Integration: Use a Microsoft-approved Consent Management Platform (like OneTrust, Cookiebot, or Didomi) that automatically passes these signals.
TCF 2.2 Framework: Use the IAB Transparency and Consent Framework to relay signals through your existing setup.

The Bottom Line:
Privacy-centric marketing is no longer “optional.” It is the new operating system for digital advertising.
