Updated November 30, 2021: We have updated the content below with additional details. Thank you for your feedback.
Currently available in public preview, this release adds support for large cases in Advanced eDiscovery, which increases the total amount of content that can be managed in a single Advanced eDiscovery case. This feature accommodates this increase in case size in response to time-sensitive, high-volume regulatory requests, investigations, and litigation in modern day regulated organizations.

With large case in Advanced eDiscovery, organizations will be able to:
Create collections with up to 1 TB of data
Commit collections with 1TB of pre-expansion data to a review set
Collect Teams chat conversations as HTML transcripts as opposed to individual items
Collect time-based content for before and after the responsive item for Teams chat conversations
Export 5 million documents or 500 GB of data (whichever is smaller) in a single export job
Manage large volume cases with more than 40 million items per case
This message is associated with Microsoft 365 Roadmap ID 85630.
[When this will happen:]
Rollout will begin in early November and is expected to be complete by early December.
