What is an email archive?
A tamper-proof, long-retention, searchable record of every email — for compliance, e-discovery and legal hold.
Not a backup. A defensible record, plus continuity if mail goes down.
Unprotected estate vs modern security — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Unprotected / signature email | Email Archive (Mimecast) |
|---|---|---|
| What it is | A backup (recovery copy) | A defensible compliance archive |
| Retention | Short, operational | Long, immutable, policy-driven |
| e-Discovery | Slow, incomplete, risky | Fast search, legal hold, cases |
| Tamper-proof | Not built to prove | Immutable, defensible |
| Outage | Business stops | Keep working (continuity) |
| End users | IT does every lookup | Self-service history |
| Recovery | Separate tool | Sync & Recover from archive |
| The platform | Records in a silo | Archive + email security together |
An archive is not a backup — it is a defensible, searchable record, plus continuity through outages. On one platform with email security.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Immutable Storage
Secure, immutable storage of every email — a tamper-proof record held to defensible standards, so it stands up to regulators and courts.
Retention Engine
Flexible, long-term retention policies — keep what regulation requires for as long as it requires, dispose of the rest defensibly.
e-Discovery & Search
Fast search across billions of messages, legal hold and case management — the e-discovery workflows legal and compliance teams need.
Continuity
If primary mail (M365, Exchange) goes down, users keep sending and receiving through the archive — an outage does not stop the business.
Platform
Part of the Mimecast platform — the archive sits alongside email security, so records and protection live together, not in separate silos.
One immutable record of every email — retention, e-discovery and continuity served from the same archive.
Twelve capabilities. Store, find, assure.
Mimecast Email Archive keeps a defensible, searchable record — compliance, e-discovery and continuity, part of the Mimecast portfolio.
Tamper-Proof Storage
Immutable, write-once storage of every email — the defensible record that stands up to regulators and courts.
Flexible Retention
Long-term retention policies tuned to your regulatory obligations — keep what you must, dispose of the rest defensibly.
Complete Capture
Captures inbound, outbound and internal email automatically — nothing missed, the full record preserved.
Petabyte Scale
Stores and indexes billions of messages at scale — the archive grows with you without slowing search.
Fast e-Discovery Search
Search billions of messages fast with rich filters — finding the email that matters in seconds, not days.
Legal Hold
Place and manage legal holds so relevant email cannot be deleted during litigation — defensible preservation.
Case Management
Case-management workflows for e-discovery — collect, review and produce email for legal and compliance efficiently.
End-User Archive Access
Users search their own archived mail via web and mobile — self-service history that offloads IT.
Email Continuity
If primary mail goes down, users send and receive through the archive — an outage does not stop the business.
Sync & Recover
Recover lost or deleted mailbox items back into the primary system — the archive as a recovery source.
Regulatory Compliance
Meets retention and records obligations across regimes — the defensible archive auditors and regulators expect.
Alongside Email Security
Part of the Mimecast platform — the archive sits with email security, so records and protection live together.

Here’s what genuinely sets Mimecast’s archive apart from a backup.
An archive is not a backup
A backup is a short-lived copy for recovery; an archive is a tamper-proof, long-retention, searchable record that can be produced for a regulator or court years later. A backup can’t satisfy retention or e-discovery. Mimecast has built archiving since 2003; it is core heritage, not a bolt-on.
Find any email, fast — for e-discovery
Litigation, regulatory requests and investigations need the right email found fast, preserved and produced unaltered, which is slow and risky from a mailbox or backup. Mimecast’s archive provides fast search across the whole record, legal hold to prevent deletion, and case workflows to collect, review and produce.
Compliance and retention, defensibly
Financial services, healthcare, legal and government must retain email for set periods and produce it on demand. That needs immutable storage, retention policies mapped to each regulation, and proof of integrity. Mimecast keeps what is required, disposes of the rest defensibly, and proves the record to auditors.
Continuity — keep working through an outage
The archive also gives email continuity. If Microsoft 365 or on-premises Exchange goes down, users keep sending and receiving through Mimecast, so an outage that would stop work becomes a non-event — real resilience from the same archive that handles compliance.
Records and protection, together
The archive sits on the same platform as Mimecast email security, so one vendor protects inbound mail, keeps the defensible record and provides continuity. You avoid separate security, archive and continuity tools, each with its own console, contract and integration gap.
The honest scope
Mimecast’s archive is mature and defensible, strongest if you run Mimecast email security, with continuity included. Microsoft Purview offers native archiving for E5 estates; Global Relay and Smarsh specialise in financial-services supervision. TechBag compares them, including migrating an existing archive.

Quick poll — what’s driving your evaluation?
Talk to an advisor“An archive isn’t a backup, as a regulatory request taught us. Mimecast’s search and legal hold stood up to the auditors.”
“e-Discovery took our legal team days; now search, hold and produce takes minutes.”
“During an M365 outage, continuity kept us sending and receiving through the archive, so it was a non-event.”
“Archive and email security on one Mimecast platform means records and protection are managed together. One less contract.”
“Retention policies mapped cleanly to our regulatory obligations — keep what we must, dispose defensibly. Audit-ready.”
“Microsoft Purview is capable if you’re all-E5, but we chose Mimecast for the proven archive, continuity and platform fit.”
“Sync & Recover pulled deleted mailbox items back into Exchange during an incident — the archive doubling as a recovery source.”
“Migrating our old archive across was the concern — TechBag and Mimecast handled it. End-users now self-serve their own history via web and mobile.”
Where everyone sits — the grids
Analyst firms bury this view behind paywalls, and review-site grids score satisfaction, not fit for your estate. So here’s TechBag’s synthesis of the email security market — tap any vendor to see why it sits where it does.

Email Archive vs the field
The native option and the archiving specialists — honest lanes; the edge is archive + continuity on the email platform.
| Dimension | Mimecast Email Archive | Microsoft Purview | Global Relay | Barracuda / Proofpoint archive | No archive (backup only) |
|---|---|---|---|---|---|
| Approach | Archive + security + continuity | M365-native | Regulated specialist | Email-vendor archive | The gap |
| e-Discovery & search | Fast, mature | Capable (E5) | Deep | Solid | None |
| Compliance/retention | Defensible, flexible | Strong (E5) | Deepest regulated | Good | None |
| Continuity | Built in | Not native | Not the focus | Sometimes | None |
| Best fit | Mimecast email shops wanting archive + continuity on one platform | All-Microsoft E5 estates | Regulated financial-services archiving-first | Buyers standardised on another email vendor | Nobody with retention obligations |

What does unmanaged email retention cost you?
Drag the sliders (count users; IT-hour cost as loaded rate). Estimates assume ~1.5 hours per user per year spent finding old mail, answering discovery and audit requests and managing mailbox storage by hand, with ~70% removed by a searchable, policy-retained archive — the avoided legal and compliance exposure is the larger, unpriced win. Illustrative.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models your actual environment and modules.
