Summary:
Microsoft Purview introduces new opt-in cmdlet parameters to remove retention holds from inactive mailboxes, enabling permanent deletion while respecting compliance. The ExcludeFromAllHolds parameter removes most holds except eDiscovery and litigation holds, and RemoveComplianceTagHold targets only Compliance Tag holds. Rollout begins December 2025.

Details:
[Introduction]
We're introducing new opt-in cmdlet parameters in Microsoft Purview Data lifecycle management that help administrators remove retention holds from inactive mailboxes. The new ExcludeFromAllHolds parameter removes all applicable holds except eDiscovery holds, litigation hold, and restrictive retention policies, enabling permanent deletion of mailboxes while continuing to respect compliance requirements.
The RemoveComplianceTagHold switch, in contrast, removes only the Compliance Tag-based hold (ComplianceTagHoldApplied) from a mailbox. This gives administrators more granular control when they want to adjust Compliance Tag enforcement without excluding the mailbox from other holds.
This message is associated with Microsoft 365 Roadmap ID 537204.
[When this will happen]
General Availability (Worldwide, GCC, GCC-High, DoD): Rollout begins in early December 2025 and completes by late December 2025.

Cost Savings through Efficient Mailbox Management
By enabling the removal of retention holds from inactive mailboxes, organizations can reduce storage costs associated with retaining unnecessary data. This can lead to lower licensing costs in the long term, especially for organizations with a large number of inactive mailboxes.
   - next-steps: Conduct an audit of inactive mailboxes and assess the potential savings from removing retention holds. Collaborate with finance to evaluate the impact on licensing costs.

explanation for non-techies**

Microsoft Purview is rolling out a new feature that allows administrators to manage retention holds on inactive mailboxes more efficiently. Imagine you have a storage room filled with boxes of old files, each with a label indicating they must be kept for a certain period due to legal or company policy reasons. Over time, some of these files no longer need to be retained, but removing them requires checking each label carefully to ensure compliance.

In the digital world, this process is similar for inactive mailboxes in Microsoft Exchange. These mailboxes might have various holds placed on them to ensure compliance with legal and company policies. The new cmdlet parameters in Microsoft Purview act like a tool that helps administrators quickly identify and remove specific labels (or holds) from these digital "boxes" without affecting others that still need to be retained.

The ExcludeFromAllHolds parameter is like a broad sweep that removes most labels, except for the most critical ones, such as eDiscovery and litigation holds. This allows for the permanent deletion of mailboxes that no longer need to be retained, provided no other legal holds are in place. On the other hand, the RemoveComplianceTagHold parameter is more precise, targeting only specific labels related to compliance tags, allowing for more nuanced control.

This change is particularly useful for organizations looking to manage their data lifecycle more effectively. By using these new cmdlet parameters, administrators can ensure that inactive mailboxes are handled in compliance with regulations while also freeing up resources by removing unnecessary data. It's important for administrators to review compliance requirements and obtain necessary approvals before using these tools, similar to getting a sign-off before disposing of physical files.

The rollout of this feature will begin in December 2025, and it will be available to administrators managing inactive mailboxes in both Exchange Online and on-premises Exchange. As with any new tool, updating internal documentation and ensuring that all relevant staff are informed will be key to a smooth transition.
