Overview
The Unmapped Participants Report gives compliance administrators visibility into communication service identities—email addresses, usernames, and other source identifiers—that have been observed in archived messages but have not yet been mapped to a User Profile in your account.
Ensuring all participants are mapped is essential for complete, auditable recordkeeping. Unmapped participants are not associated with a user record, which means their communications may not be subject to your firm's retention policies, supervisory review workflows, or risk scoring.
Why This Matters
When a message is ingested into eComms Keep, the platform attempts to match each sender and recipient to a known User Profile. If no match is found, that participant is flagged as unmapped.
Unmapped participants create gaps in your compliance program:
Their communications may not be retained according to firm or regulatory policy.
They will not appear in supervisory review queues or be subject to alert detection.
They cannot be included in user-level reporting or audit trails.
The Unmapped Participants Report is the primary tool for identifying and resolving these gaps.
Accessing the Report
Navigate to Analytics > Reports.
Click New Report.
In the dialog that opens, select Unmapped Participants Report.
Access to this report is restricted to users with the Administrator role.
Report Parameters
When creating a new report, the following parameters are available:
Parameter | Description |
Report Type | Set to Unmapped Participants Report. |
Date Range | Select a start and end date, or choose a preset period (e.g., Last 30 Days) to limit results to participants observed in messages ingested within that window. The maximum date range is 90 days. |
Once configured, click Create Report.
Report Output
The report is delivered as a CSV file. Each row represents a unique unmapped participant identifier observed within the selected date range.
Column | Description |
Identity | The source identifier (e.g., email address) as observed in archived messages. |
Display Name | The display name associated with the identifier, if available. |
Source | The communication channel where the identifier was observed (e.g., Email). |
Sent Message Count | Total number of messages in the archive that include this identifier. |
Earliest Message Date Sent | Timestamp of the oldest message in the archive involving this identifier. |
Latest Message Date Sent | Timestamp of the most recent message in the archive involving this identifier. |
Resolving Unmapped Participants
After identifying unmapped participants, administrators have two options:
Map to an existing user If the identifier belongs to a current employee or known contact, map it to the appropriate User Profile. Once mapped, the platform can reprocess archived messages to associate them with that user record.
Create a new user If no User Profile exists for the individual, create one and assign the identifier to it.
Note: Mapping a participant after the fact does not automatically make their historical communications visible in supervisory review or subject to policy-based risk scoring. A reprocess must be triggered separately which can be requested through MCO Customer Support.
Unmapped Message Retention
Messages that do not include any known participants from your organization are subject to a separate retention setting: Retention Period for Unmapped Messages, found under Settings > Account Defaults. This defaults to 90 days.
Unmapped messages will be permanently deleted once their retention period expires. To ensure unmapped messages are retained longer, either adjust the retention period or map at least one of the message's participants to a User Profile in the system.
