Microsoft Defender for Office 365: Update to Quarantine notification default logo

We are updating the default logo within the Quarantine notification email that is sent to users.

When this will happen:

  • Standard Release: We will begin rolling this out in early April and expect the rollout to be completed by mid-April.
  • Government: We will begin rolling this out in mid-April and expect the rollout to be completed by late April.

How this will affect your organization:

We will be replacing the legacy “Office 365” logo with a new “Microsoft” logo to better align with our current branding.
