A message your team needed is missing. Caught in a spam filter that was a touch too aggressive. Dropped during the MX propagation window of a tenant cutover. Pulled into a phishing-protection takedown. Or just deleted by a user who is now insisting they never received it. The traditional answer, restore from backup, is the wrong tool for the per-message case. Message Replay is the right one.
Backup is for catastrophic failure. Hours-long restore times. Request queues. The mailbox restored to a specific point in time with every flag and folder intact. That is the right answer for the rare event where a server is on fire. It is the wrong answer for the everyday case, the one message that needed to land and did not, the false-positive batch that should be released, the cutover-window gap that needs sweeping up after the fact.
Message Replay is purpose-built for those everyday cases. It sits in the mail-flow path, captures inbound and outbound continuously, and exposes a 45-day window of replayable messages. The archive is rolling, so older content purges itself on the back end while the working window stays current. Recovery is single-click. The recipient sees the message arrive as though it had been delayed in transit, because operationally that is what just happened.
Message Replay is part of the broader Route group, the products that handle mail movement through migrations, outages, and cutovers. It is the cross-cutting recovery layer behind several of the others.
A rolling archive, a search index over it, and a single-click replay button. Six things the platform does so the recovery process is a conversation, not a project.
Inbound and outbound mail captured continuously and held in an encrypted store for up to 45 days. Anything that touched your domain in that window is recoverable on demand. The window rolls forward automatically; the archive purges itself on the back end.
Pick a single message, a thread, or a batch. Replay it back into the destination mailbox. The recipient sees it arrive as though it had been delayed in transit. No restore queue, no helpdesk ticket lifecycle, no waiting for backup tapes to spin up.
Find the message you need by sender, recipient, subject, or content. The archive is searchable so you do not have to guess at timestamps or know exactly when something disappeared. Useful when a user reports "I never got that thing from finance" three days after the fact.
The archive is encrypted in storage and access is scoped to your tenant. This is a recovery layer, not a public spool. Treat it as part of your mail infrastructure security boundary.
Built specifically for the cases where the day-to-day mail flow loses something it should have kept. Tenant migration MX propagation gaps. Phishing-protection takedowns that pulled in legitimate senders. Spam-filter false positives that were emptied before anyone checked. Replay handles all of them.
No agent on endpoints. No connector to install in the mail server. Sits in the mail-flow path and captures the stream as it goes through. Adding it to an existing environment is a configuration change, not a deployment project.
Tenant migration cutovers. Customers running a Microsoft 365 or Google Workspace tenant move use Message Replay alongside Backup MX as the cutover-week safety net. If anything slips through during the MX propagation window, replay puts it where it belongs after the fact.
Phishing-protection takedowns. When a phishing rule triggers and pulls down a wider set of messages than intended, replay puts the false-positive batch back into the right inbox. The takedown does its job; the collateral gets reversed without rebuilding the rule from scratch.
Spam-filter false positives. Most quarantine systems offer a release function. Message Replay covers the cases where the user emptied quarantine without checking, where the false positive surfaced after the retention window of the filter itself, or where the volume of releases makes per-message work unreasonable.
You need long-term regulatory archiving. Multi-year retention, compliance hold, eDiscovery, structured retention policies. Message Replay is a 45-day operational recovery layer, not a regulatory archive. The two coexist, but they answer different questions.
You need full mailbox backup and restore. Every folder, every flag, every metadata field, restored to a specific point in time. Backup tools are the right shape for that. Message Replay handles the per-message case, which is a different problem.
Your environment never produces missing messages. If your spam filter, mail server, and migration cadence have been clean for years and your help desk does not see recovery tickets, Message Replay is overhead you do not yet need. We would rather you call us once the recovery pattern shows up than pay for a layer you do not use.
When you contact us about Message Replay, you talk to someone who has actually used it during real cutovers and false-positive recoveries. We tell you whether your environment needs it, what retention window fits your recovery patterns, and how it sits next to your existing backup and quarantine layers.
Reference calls with existing Message Replay customers are available on request. Most enterprise customers prohibit logo use, but they will take a phone call from a serious prospect to vouch for what we actually do in production.
Same-day response. Real expert on the call. We tell you whether the per-message recovery pattern shows up in your environment and what to do about it.
