M365 Changelog: Emails Related to AAD Groups are Changing Format

MC384327 — Updated May 26, 2022: Microsoft has updated the content below to show as intended. Thank you for your patience.

When using Microsoft 365 and Security groups, emails are sent to users in the following scenarios:

  • Email sent to group owner when a user requests to join their group
  • Email sent to requestor when group owner approves or denies their request
  • Emails that occur when group expiration is enabled (Microsoft 365 groups only)

Microsoft is using a new service to send these emails, resulting in the look of the emails changing.   

When this will happen:

Microsoft will begin rollout in late June and complete rollout by early July.

How this will affect your organization:

Anyone in your organization who uses groups will continue to receive emails during the scenarios listed above, however, these emails will have a new format and appearance.
