Services
Analytics
Quick snapshot of your tenant: user count, license usage, storage, and service activity at a glance.
Deep-dive into trends, growth rates, and breakdowns across all M365 services with interactive charts.
Interactive visual map showing how users, groups, and SharePoint sites are connected across your tenant.
AI-powered analysis of your M365 security posture across authentication, identity, conditional access, and threat detection.
Probes OneDrive and SharePoint endpoints on a schedule to track throttled responses and latency trends.
Migration
Exact replica of Exchange mailboxes and OneDrive content, folders, metadata, and timestamps all preserved.
Run multiple migrations in one task. Supports 1:1, 1:many, and many:many patterns for large-scale rollouts.
Visual mapper to design migration paths. Define source-to-target pairs and preview the plan before execution.
Migrate emails, files, or both, choose exactly what you want to move and control how the transfer is handled with precision.
Security Testing
Go beyond basic data generation. Simulate real-world security threats directly inside your Microsoft 365 lab tenant to validate DLP policies, SIEM detection, and incident response playbooks.
Inject realistic, checksum-valid sensitive data into Exchange emails, OneDrive files, and SharePoint documents to verify your DLP policies catch what they should. Every generated value passes the same format validation that real DLP engines use.
Simulate a real ransomware attack on OneDrive or SharePoint files, then roll it back completely. Validate SIEM alerts, incident response playbooks, and backup recovery procedures in a controlled lab environment.

AI Email Threads
One click turns your tenant into a living workplace. AI writes a full email thread, a real subject, a genuine back-and-forth, and drops it straight into everyone's mailbox.
AI plans the whole exchange, a real subject and replies that build on each other. Up to 50 messages per thread.
Every message lands for real, senders in Sent Items, recipients in their Inbox, across all participants.
Each person writes from their job role, with quoted reply chains and signatures, just like Outlook.
MCP Ready
Expose the simulator as an MCP server so AI agents and copilots can trigger data generation programmatically.
Let your AI assistants populate tenants on demand through natural language commands via the MCP interface.
Each M365 service is exposed as an individual MCP tool, giving fine-grained control over what gets generated and how.
Lucien
Lucien is the conversational AI assistant embedded directly inside the tool. Ask it anything about M365 Data Simulator and get instant, accurate answers without leaving the page.
Lucien knows every feature of the tool, generators, automation flows, scheduling, analytics, DLP, MCP, and more. Ask any question about configuration, prerequisites, or options.
Write your question in any language and Lucien replies in the same language. No configuration needed, it detects your language automatically.
Lucien runs on your own OpenAI or Anthropic API key configured in Settings. No third-party proxy, no data leaving your session, your key, your model, your control.
