MRM is a key feature in Office365 that applies to data stored on the platform to help organizations meet business, legal, and regulatory requirements. For example, a bank may be required to maintain records about specific transaction types, yet it will not want to implement a blanket “store everything” policy that could overwhelm even the generous storage limits in Exchange Online. Alternatively, a health provider may not want staff inadvertently sending out email messages that contain patients’ insurance policy numbers. Finally, organizations that work in regulated environments may have to provide strict tracking and auditing of all communications within the company.
