As you may have seen, Microsoft has sent out a notification to all its advertisers in the EEA, the UK, and Switzerland, reminding them that, starting May 5, 2025, Consent Mode activation will be mandatory.

All advertisers using Microsoft Advertising will be required to send a valid consent signal in order to continue collecting and using conversion data. Without it, your campaigns may suffer from reduced performance and accuracy.
Good news: Sirdata ABconsent CMP handles everything for you! 🥳
If you're using Sirdata ABconsent CMP, there's nothing you need to do! The Microsoft UET Consent Mode is already automatically supported for all clients who:

What do you need to do?
