What LepideAuditor for Exchange Server Does

LepideAuditor provides visibility into configuration changes, mailbox activities, permission changes, and administrative actions across Exchange servers and Exchange Online (part of Microsoft 365). It collects and centralizes audit data, presents it in user-friendly dashboards and reports, and enables real-time alerts for suspicious or non-compliant activity.

Key capabilities include:

Change auditing for mailboxes, database, transport, and configuration objects.
Mailbox activity tracking (send/receive, mailbox logins, folder access).
Permission and role change detection (delegation, group membership, role assignments).
Pre-built and customizable reports for compliance (HIPAA, GDPR, SOX).
Real-time alerts via email, console, or ticketing integration.
Searchable audit trail with filtering, export, and scheduled delivery.
Support for both on-premises Exchange and Exchange Online.

Typical Use Cases

Compliance reporting for regulations requiring audit trails.
Detecting insider threats or compromised accounts by monitoring abnormal mailbox activity and logins.
Operational troubleshooting by tracing configuration changes and mail flow modifications.
Change control validation — ensuring changes were authorized and documented.
Forensic investigations after security incidents.

Planning Your Deployment

Before installing LepideAuditor for Exchange Server, plan for scope, prerequisites, and architecture.

Scope and Objectives

Decide whether you’ll audit on-premises Exchange, Exchange Online, or hybrid environments.
Define which objects and events matter (mailboxes, transport rules, connectors, permissions, etc.).
Identify compliance/reporting requirements and retention policies for audit logs.

System Requirements (typical)

A Windows Server to host LepideAuditor components (check current vendor docs for exact OS/.NET/SQL versions).
SQL Server (Express or Standard) for the repository/database.
Service account(s) with appropriate Exchange and AD permissions for data collection.
Network access between Lepide server and Exchange servers/Domain Controllers.

Permissions

For on-prem Exchange: service account with Exchange View-Only Organization Management role or higher for some operations; additional rights to read mailbox audit logs and Exchange configuration.
For Exchange Online: an Azure AD service account with the required Exchange Online roles and appropriate API permissions (e.g., View-Only Audit Logs, or roles required for mailbox access via Graph/PowerShell APIs).
Permission to query Active Directory for object and permission auditing.

Installation Overview

This section provides a high-level installation and configuration workflow. Exact steps may vary by LepideAuditor version; consult product documentation for version-specific details.

1. Prepare the Server and Database

Provision a Windows Server that meets prerequisites.
Install .NET framework components required by Lepide.
Install SQL Server (Express for small deployments or Standard for enterprise); create a database instance dedicated to LepideAuditor or allow the installer to set one up.

2. Download and Run the Installer

Obtain the LepideAuditor installer from your vendor portal.
Run the installer as an administrator on the designated server.
During setup, choose the components you need (central server, file server auditing agents, SharePoint/Exchange connectors if offered separately).

3. Configure the Lepide Console

Launch the Lepide management console or web UI.
Connect the console to the SQL database created earlier.
Set up service account credentials securely in the console for auditing tasks.

4. Add Exchange Sources

For on-prem Exchange:
- Add your Exchange servers or Exchange organization in the Lepide console.
- Provide service account credentials with necessary Exchange permissions.
- Configure the types of audit data to collect (configuration changes, mailbox activities, logons).
For Exchange Online:
- Register and authenticate the Lepide application with Azure AD if required.
- Grant API permissions and consent as per vendor instructions.
- Configure connectors to pull mailbox audit logs and configuration information.

5. Configure Audit Settings and Retention

Define what events to audit — e.g., mailbox access, send-as, permission changes, transport rules, database operations.
Set retention rules for audit data in the SQL database and plan for archiving/exporting older records to reduce storage use.

6. Set Up Reports and Alerts

Use pre-built reports for compliance (user activity, mailbox access, top changes).
Customize and schedule reports to run and be emailed to stakeholders.
Create alert rules for high-risk activities (multiple failed logons, export of mailboxes, permission escalations) and configure delivery (email, SNMP, webhook, ticketing).

Key Features — Deep Dive

Change Auditing and Object Tracking

Tracks configuration changes to Exchange objects: mailboxes, connectors, transport rules, databases, DAGs, policies.
Stores before-and-after values so you can see exact changes and who made them.

Mailbox Activity Monitoring

Monitors mailbox logins, message send/receive, mailbox moves, mailbox permission changes.
Supports mailbox audit log ingestion for detailed user activity.

Permission & Role Auditing

Detects changes to mailbox and database permissions, delegation assignments, and administrative role changes.
Useful for detecting privilege escalation or unauthorized delegation.

Alerts & Real-Time Monitoring

Real-time alerting reduces time-to-detect for suspicious activities.
Thresholds and correlation options allow tuning to reduce false positives.

Reports & Compliance

Pre-built compliance templates (HIPAA, PCI, GDPR, SOX).
Custom report builder for regulatory or internal needs.
Export formats: CSV, PDF, XLSX; scheduled distribution via email.

Searchable Audit Trail

Centralized, indexed store with rich filtering (time range, user, action, object).
Quick forensic lookups and ability to export raw audit logs for deeper analysis.

Example: Creating a High-Priority Alert (Typical Steps)

In the Lepide console, go to Alert Rules.
Create a new rule: choose event category (e.g., Permission Change).
Add filters: target object type (Mailbox), actor(s) (exclude service accounts), severity (High).
Set conditions: e.g., if permission change results in Full Access or Send As permissions to non-admin users.
Configure actions: send email to security team, create a ticket via webhook, or raise an audible alert.
Test the rule by making a controlled permission change and verifying alert delivery.

Reporting Examples

Daily Summary: number of mailbox logins, failed logins, and permission changes.
Compliance Audit Report: all changes to mailboxes and transport rules in the last 90 days.
Forensic Report: detailed audit trail for a specified mailbox between two timestamps, including before/after values.

Use scheduled reports for regular stakeholder updates and ad-hoc searches for investigations.

Best Practices

Use least-privilege service accounts and rotate credentials regularly.
Start with broad auditing during initial deployment, then refine filters to reduce noise.
Tune alerts to company risk tolerance to avoid alert fatigue.
Archive old audit data off the production SQL instance to maintain performance.
Integrate alerts with your SIEM or ticketing system for centralized incident response.
Regularly test alerting and reporting workflows to ensure they function after updates or configuration changes.

Troubleshooting Tips

If events aren’t appearing, verify service account permissions and connectivity to Exchange/Office 365.
Check the Lepide service and SQL service logs for errors related to ingestion or DB writes.
Ensure mailbox audit logging is enabled where necessary (Exchange Online has mailbox audit defaults; on-prem may need configuration).
For missing details, confirm API permissions/consent for Exchange Online connectors.
Run the Lepide connectivity tests (if provided) to validate configuration.

Licensing and Support Considerations

LepideAuditor is typically licensed per server or per user/mailbox depending on deployment and vendor packaging. Confirm with your vendor on licensing metrics, support SLAs, and update policies. Keep software and connectors up to date to remain compatible with Exchange and Microsoft 365 API changes.

Conclusion

LepideAuditor for Exchange Server helps organizations maintain visibility, enforce compliance, and accelerate investigations by providing detailed, centralized auditing of Exchange environments. Proper planning—covering scope, permissions, storage, and alert tuning—combined with regular testing and integration with your security operations will maximize its value.
