Classic EAC retirement: Mail flow features

From Microsoft Corporation
Technical Bulletin MC295841 · Published Nov 2, 2021

Message Summary

As a follow-up to the classic Exchange admin center (EAC) retirement announcement (MC283874 – Sept), we want to let Exchange Online customers know that we will be retiring the mail flow features from the classic EAC beginning in early December 2021.

You are receiving this message because our reporting indicates one or more users in your organization are using the classic EAC.

Mail flow features that we are retiring from the classic EAC include:

  1. Message Trace
  2. Remote domains
  3. Accepted domains
  4. Connectors

Key points

  • Timing: Retirement: Early December through mid-December.
  • Action: We recommend you go to the new modern EAC to use the modern version of these features where we will continue to invest our development resources.
  • Roll-out: tenant level

How this will affect your organization:

Exchange admins will no longer be able to access these pages once this change occurs. Beginning now, if an admin clicks on any of the above feature links in the classic EAC, a banner with a link to the new home for these features will be displayed to make it easier to locate the new home for these features.

What you need to do to prepare:

Instead of using the classic EAC for these features, begin using the modern EAC now.
