Voice MFA custom greetings retire February 28; Entra documentation clarifies agent permissions and recommendation emails

After that date, MFA voice calls will use Microsoft’s default recordings.

No new feature or general availability announcement is represented.

After the retirement, voice calls will use Microsoft’s default recordings. Organizations should prepare users for the changed prompts and review their MFA configurations.
- Conditional Access Optimization Agent identity behavior is clarified
Entra ID · Conditional AccessAn updated Conditional Access article explains that an agent enabled before Microsoft Ignite 2025 could fail if the activating account required PIM role activation but did not have the required permissions when the agent ran. Agents turned on after November 17, 2025 no longer use the identity of the user who activated them. This is a documentation clarification that may affect assessment of older agent deployments and rollout plans.

It also clarifies that the messages are informational, not promotional or marketing emails, and contain no upselling content.

So when the agent attempted to run, it failed because the account didn't have the required permissions at that time. Conditional Access Optimization Agents that were turned on after November 17, 2025 no longer use the identity of the user who activated the agent.
