How to Recover a Shared Mailbox After an Accidental Retention Policy Change

A retention change can remove items earlier than expected or place messages into a recovery area.

Checks to make

Confirm policy change history and affected date range, preserve audit records, and review available recoverable items and backups. Restore into a controlled mailbox or folder first, validate ownership and contents, and correct the policy before normal use resumes.
