Message Summary
This post applies to customers with Exchange Online Protection and Microsoft Defender for Office 365 plan 1 and plan 2 service plans.
We will be updating how tenant and user allows are handled in the filtering stack to better align with customer expectations. These changes will provide more controls for the tenant administrators and ensure that users are better protected.
This message is associated with Microsoft 365 Roadmap ID 115505
When this will happen:
Rollout will begin in late August 2023 and is expected to be complete by late September 2023.
How this will affect your organization:
You may see some changes in the ordering and thus items may be junked/quarantine when they may have been previously allowed.
To understand the ordering of user and your organizational allow and block, please visit order and precedence of email protection.
What you need to do to prepare:
You don’t need to do anything, however, if you would like to update your organizational allows and blocks across different places, please feel free to do so.
If you have any feedback, please provide it from this Message center post using the text box after you do thumbs up or thumbs down as it will directly reach the responsible team.
