Microsoft 365 compliance center – Public preview of historical versions for Advanced eDiscovery

Coming soon (public preview), historical versions in Advanced eDiscovery allows organizations to quickly search across not only the current version of documents, but all the versions that may be relevant given the content included in the document at the time of the version.

This message is associated with Microsoft 365 Roadmap ID 81898.

When this will happen:

Rollout will begin in early November and is expected to be complete by early December.

How this will affect your organization:

If a SharePoint administrator has versioning enabled on the site, when documents are modified in SharePoint, implicit regular versions are created as the document is saved (or auto-saved). These older versions remain available, and your organization may be required to share older versions that have sensitive or relevant content during court discovery in a legal matter.

After eDiscovery administrators turn on the historical versions feature for their organization and specify the SharePoint sites to enable crawling and indexing of all the historical versions, Advanced eDiscovery users will have the ability to search across all versions of documents or locations in scope for the investigation or a case.

What you need to do to prepare:

Assess if the historical versions feature is beneficial for your organization’s eDiscovery purpose. You may wish to provide training to all eDiscovery users in your organization and update relevant documentation.

  • Turn the feature on globally for all cases in your organization via the Advanced eDiscovery settings Page.
  • After the feature is turned on, eDiscovery administrators can specify up to 100 sites per tenant to enable crawling and indexing of document versions.
  • Perform keyword searches on the specified sites and discover versions of documents containing the keyword specified.

This update will not affect your organization’s current eDiscovery workflow. Once this feature is enabled by an eDiscovery administrator, all subsequent collections performed on enabled sites will return versions of documents if those versions match the keyword specified in the collection query text.

Note: This feature is free of charge to try during the public preview phase, with organizations able to turn on up to 100 sites per tenant. More information on the pricing and licensing model for this feature will be communicated in advance of general availability in H2 2022.
