In-Place Hold and Litigation Hold in Exchange 2016

Organizations are required to preserve electronically stored information (ESI) including email, when there is any judicious expectation of litigation exists.

It could be all email related to a specific topic or all email for certain individuals. Depending on the organization’s electronic discovery (eDiscovery) practices, the following measures can be executed to preserve emails:

  • End users may be asked not to delete the emails; however, users can delete email knowingly or accidentally.
  • Automated deletion mechanisms such as messaging records management (MRM) can be stopped/ suspended. This could result in filling the user mailbox. In this also users can delete email knowingly or accidentally.
  • Can copy or move email to an archive to make sure it isn’t deleted, altered, or tampered with. This increases costs.

Failure to preserve email will uncover an organization by legal and financial risks such as scrutiny of the organization’s records retention and discovery processes, adverse legal judgments, sanctions, or fines. In order to overcome these issues and preserver the email/mailbox content Exchange server 2016 has two types of holds called Litigation Hold and In-Place Hold.

Litigation Hold: Litigation Hold uses the LitigationHoldEnabled property of a mailbox. When Litigation Hold is enabled, all mailbox items are placed on hold.

In-Place Hold: In-Place Hold preserves all mailbox and public folder content, including deleted items and original versions of modified items. All such items can be returned in an In-Place eDiscovery search. When a user’s mailbox is placed on an In-Place Hold, the contents in the corresponding archive mailbox (if it’s enabled) are also placed on hold and returned in an eDiscovery search. You can place multiple In-Place Holds on a mailbox, but Litigation Hold is either enabled or disabled for a mailbox.

NOTE: In both Litigation Hold and In-Place Hold, we can specify the duration period to hold items. The duration is calculated from the date a mailbox item is received or created. If a duration isn’t set, items are held indefinitely or until the hold is removed
