Comparison Table
Microsoft Purview
enterpriseMicrosoft 365 compliance software for retaining and retrieving Exchange Online email.
Legal hold and retention policies managed through Purview compliance experiences drive recovery readiness for Exchange Online mailboxes.
Microsoft Purview performs mailbox recovery by applying Microsoft 365 retention and hold policies across Exchange Online data, then restoring content using eDiscovery workflows and Exchange recovery features. Purview integrates with Microsoft Information Protection and eDiscovery cases so administrators can preserve, search, and export message content with audit log visibility.
The automation surface comes from Purview compliance workflows plus Microsoft Graph-based management for policy configuration, search, and exports. For email restoration, it emphasizes governance controls like RBAC, retention hold management, and immutable audit trails rather than standalone backup restore tooling.
- +Retention hold and legal hold workflows cover mailbox deletion scenarios
- +RBAC and audit logs support compliant administration of recovery-related actions
- +eDiscovery case tools enable targeted search, export, and evidence handling
- +Microsoft Graph supports policy and compliance automation for recovery operations
- –Purview does not provide point-in-time restore of message state like backup snapshots
- –Correct recovery depends on retention and hold configuration set before deletion

Best for: Fits when teams rely on Microsoft 365 governance controls and eDiscovery workflows for deleted-message recovery.
Datto Backupify
SMBCloud-to-cloud backup software for recovering Google Workspace and Microsoft 365 email.
Granular mailbox restore from backups with selectable destinations, enabling targeted recovery without full mailbox rollback.
Datto Backupify is designed for deleted message recovery and mailbox item retention scenarios where the primary requirement is restoring mail content with correct message structure and attachments. Restoration workflows cover both one-off message retrieval and bulk operations to return multiple items after a workflow mistake. Admin setup centers on connecting protected Microsoft 365 or Google Workspace mailboxes and keeping retention aligned to the organization’s recovery point objective.
A practical tradeoff is that Backupify is strongest for recovery actions after data loss events, not for real-time prevention of inbox issues like policy-based quarantine. It fits best when helpdesk teams need predictable restoration runs for accidental deletions, shared mailbox cleanup, or after an email retention gap is discovered. Governance depends on disciplined retention and restore request handling since recovery success is bounded by what was backed up within the retention window.
- +Granular restore enables message-level and folder-aware recovery
- +Bulk restore supports faster remediation for large accidental deletions
- +Retention-aligned recovery reduces reliance on mailbox vendor restore paths
- +Operational workflow fits helpdesk recovery requests with repeatable steps
- –Best fit is recovery workflow execution rather than inbox protection controls
- –Restore operations require planning for folder placement and destination selection
- –Governance depends on correct retention configuration before incidents
- –Cross-account recovery needs explicit mapping to target mailbox destinations

How to Choose the Right Email Recovery Software
Options for email recovery software differ most in how reliably they find lost messages, how far back they can restore, and what controls you have over the recovered results. In practice, the gaps show up under message recovery scope and restore preview.
Recovery scope coverage
Why it matters
Recovery scope coverage determines whether you can recover only recent items or also older, partially deleted, or corrupted cases. For email recovery software, users need the right coverage for the incident they’re actually trying to fix.
How to check
In a demo, ask about what kinds of loss it handles: mistaken deletion, drafts, and items missing after a change. Then request a demo workflow that shows selection of a specific date range and the resulting message list before restoring.
Restore preview before apply
Why it matters
Restore preview before apply helps you verify the right messages and attachments before anything overwrites or duplicates. With email recovery software, that reduces the risk of restoring the wrong threads or incomplete content.
How to check
Look for a “preview” or “review results” step that shows subjects, senders, timestamps, and attachment presence. Ask the demo to restore one item twice and confirm whether it deduplicates or creates copies based on the preview decision.
Search accuracy across recovered items
Why it matters
Search accuracy across recovered items matters because recovery often returns many candidates. If results are noisy, it takes longer to identify the correct emails and threads after recovery.
How to check
Test the product search on a small sample dataset: search by sender, subject keywords, and date. Then compare the returned list to what’s in the recovered preview, not just what the original mailbox shows.
Attachment and thread integrity controls
Why it matters
Email recovery software succeeds only if attachments and conversation structure remain usable. Attachment and thread integrity controls help avoid broken files or scrambled message grouping.
How to check
In the demo, pick a message with at least one attachment and confirm the restored attachment opens correctly. Also ask how it handles conversation views: does it restore the correct thread ordering or metadata so replies remain connected?
Mailbox connection and environment compatibility
Why it matters
Mailbox connection and environment compatibility affects whether recovery actually reaches the source data you care about. If the tool can’t connect in your setup, the rest of the features won’t help.
How to check
Ask what connection methods it supports in your environment and whether it can target specific mailboxes or only the whole system. Confirm with a demo that it can run a recovery against one test mailbox without affecting others.
Audit log and export of results
Why it matters
Audit log and export of results provide traceability for what was recovered, when, and how. For email recovery software, that’s important when multiple admins handle incidents or when recovery outcomes must be documented.
How to check
Check whether each recovery run records who initiated it, what it matched, and what it restored. Request an export format (CSV or report) that lists restored items and includes message identifiers and attachment status.
Red flags
- No clear preview step, so recovered results can’t be validated before applying.
- Recovery scope only covers one scenario or a narrow time window.
- Attachment checks and restore outcomes can’t be verified in a demo workflow.
Fit by situation
- If you’re recovering after mistaken deletion with uncertain dates, prioritize recovery scope coverage.
- If your team needs to confirm correctness before any restore, prioritize restore preview before apply.
- If you routinely recover messages with attachments and threads, prioritize attachment and thread integrity controls.
