M365 Changelog: Microsoft 365 Compliance Center Core eDiscovery – Search by ID list retirement

MC291088 – Updated October 13, 2021: Microsoft has updated this message with additional details for clarity.

Microsoft will be retiring the option to Search by ID list, as it is not functioning to an adequate level and creates significant challenges for organizations who depend on consistent and repeatable results for eDiscovery workflows.

When will this happen:

Microsoft will begin making this change in mid-November and expect to complete by the end of November.

How this will affect your organization:

You are receiving this message because Microsoft’s reporting indicates your organization may be using Search by ID list.

Once this change is made, the option to Search by ID list will be removed. Microsoft suggests focusing on search by query, condition and/or locations rather that ID.

What you need to do to prepare:

To fix this problem you need to review your eDiscovery search process, and update the workflow to focus on search by Subjects and dates rather than Search by ID list. Upon export from Core eDiscovery you can explore options to refine to only the messages of interest.
