Hi,
The ability to postpone enforcement until September 30, 2025 is supposed to be available starting in the second half of this month. Please see article below which has instructions as well as link to portal page to postpone.
Request more time to prepare for enforcement
Excerpt:
We understand that some customers may need more time to prepare for this MFA requirement. Microsoft is allowing customers with complex environments or technical barriers to postpone the enforcement for their tenants until September 30, 2025.
Starting in 2nd half of February 2025, Global Administrators can go to the Azure portal to select the start date of enforcement for their tenant for admin portals in Phase 1. Global Administrators must elevate access before they can postpone the start date of MFA enforcement.
Global Administrators must perform this action for every tenant where they want to postpone the start date of enforcement.
By postponing the start date of enforcement, you take extra risk because accounts that access Microsoft services like the Azure portal are highly valuable targets for threat actors. We recommend all tenants set up MFA now to secure cloud resources.
