Details:

In Safe Attachment policies, as part of Phase 1 changes for ‘Replace’ action retirement (MC424901 August '22), the behavior of the ‘Block’ action was applied to the policies configured with ‘Replace’ action.
As part of Phase 2 of the ‘Replace’ action retirement work, the ‘Replace’ action selection will be removed from the Safe Attachment policies (Microsoft 365 Defender portal and cmdlets). As part of this change, any policies still configured with the ‘Replace’ action will be automatically changed to the ‘Block’ action.

[When this will happen:]
This change will start rolling out from mid-April 2023 and worldwide deployment will be complete by mid-May 2023. For Government clouds, the deployment will start in mid-June 2023 and will be complete by late-June 2023.
