Estimated reading time: 1 minute

Litigation hold preserves a mailbox and its contents from being modified or removed for eDiscovery purposes. A user can continue to send and receive email whilst litigation hold is enabled, even delete an item from the mailbox, and Office 365 will retain the items for discovery purposes.

Litigation hold is not enabled by default, and legal teams will need to proactively enable the feature to avoid users potentially deleting any critical data elements. The duration for the hold can also be specified. This is calculated from the date a mailbox item is received or created. If a duration is not set, items are held indefinitely or until the hold is removed.
