Multifactor Authentication deadline on 15th October

Question

Will the Multifactor Authentication deadline on 15th October 2024 affect my Microsoft 365, Exchange Online End Users? Will they need to setup MFA to just access their email accounts?

The users do not access any of the following Azure portal, Microsoft Entra admin center, and Intune admin center.

Thank you for posting this in Microsoft Q&A.

As I understand you want to know if enforcing MFA will affect Microsoft 365, Exchange Online End Users.

No, as of now there will not be any impact on Microsoft 365, Exchange Online End Users.

Enforcement for the MFA requirement at Azure sign-in will be rolled out in phases:

Phase 0: Starting August 15, 2024 all customers will be notified that this enforcement will be coming to their tenants in 60+ days. They will be directed to this page for more information and steps on how to request a grace period.

Phase 1: Starting in October 15, 2024, enforcement for MFA at sign-in for the Azure portal , Entra portal and Intune portal will roll out gradually to all tenants. This phase will not impact any other Azure clients, such as Azure CLI , Azure PowerShell and IaC tools. This phase is expected to last until March 2025.

Phase 2: Starting in early 2025, enforcement for MFA at sign-in for Azure Command Line Interface (CLI), Azure PowerShell and Infrastructure as Code (IaC) tools will gradually roll out to all tenants.

We will also allow a grace period if you have any use cases where no workarounds are easily available and who need additional time (beyond the start date of enforcement for their tenants) to prepare for the MFA requirement at Azure sign-in.

Let us know if you have any further questions.

Hi Mark,

This will not affect your end users since they do not use the three admin portals. Please reference article below for confirmation of affected applications:

Please note that you may postpone enforcement to March 15, 2025 if needed:
