@owenmurr That's correct - WW release of Advanced Delivery has been delayed until the end of this month. We are keeping the following MC post updated with timeline for customers: MC256473, (Updated) Microsoft Defender for Office 365: Introducing Advanced Delivery for Phishing Simulations and SecOps Mailboxes. Thank you for your patience. Looking forward to getting this feature out to customers.
