Companies and individuals must be aware of their legal obligations to preserve communications when involved in government investigations or litigation, especially in light of new preservation standards from the Federal Trade Commission and Department of Justice. Due to concerns with the increased use of collaboration tools like Microsoft Teams and ephemeral messaging applications like Signal, the agencies are updating the language they include in standard preservation letters and requests for information, including second requests, voluntary access letters, civil investigative demands, other compulsory legal processes and grand jury subpoenas.
