Microsoft 365 Email Archiving
Capture Microsoft 365 and Exchange Online email into a separate, immutable archive — with retention, legal hold, and fast eDiscovery that go beyond native M365.
WORM-backed · SEC 17a-4, FINRA, HIPAA & CJIS-ready · 60+ data sources
Why archive Microsoft 365 email separately?
Microsoft 365 email archiving captures Exchange Online mail into a tamper-evident archive independent of the mailbox, so records stay complete, searchable, and defensible even if a user or admin deletes them. A dedicated archive adds true immutability, granular retention, supervision, and minutes-not-months eDiscovery that native M365 retention and Purview do not fully cover — and it extends to Teams, SharePoint, and 60+ other sources.
