Configuration-as-Code for Microsoft 365
Deploy baselines. Detect drift. Stay compliant. Manage M365 configurations across all your tenants with GitOps.
Why OM365DO?
Built by MSPs, for MSPs. We solved the problems we faced managing hundreds of M365 tenants.
Groups First
Use {{GROUP:name}} templates in your configs. OM365DO resolves names to IDs at deployment, so one baseline works everywhere.
GitOps Native
Azure DevOps pipelines with WhatIf preview, approval gates, and full audit trail. Every change tracked in Git history.
Multi-Tenant Ready
One baseline repository, deploy to unlimited Tenant tenants. Separate assignments per tenant, consistent configurations.
Detailed Feedback
Clear, actionable output for every policy. Know exactly what changed, what failed, and why. No more cryptic DSC errors.
GCC High Support
Full support for Government Cloud environments. Same workflows, same baselines, just point to the right cloud.
Separate Assignments
Policy configs and assignments in separate files. Change who gets a policy without touching the policy itself.
Daily Automated Backups
Every client's full M365 configuration is exported to Git each night. Full point-in-time restore from any date in history.
Per-Client Flexibility
A .baseline-ignore file in each tenant repo lets MSPs opt specific policies out per client without touching the shared baseline.
Resource Protection
Any M365 resource with OM365DO:IGNORE in its description is skipped. Clients can lock their own customizations from being overwritten.
No Local Tools Required
Everything runs in Azure DevOps cloud. MSP staff need only a browser and a text editor — no PowerShell, no modules, no local setup.
Auto Pipeline Self-Healing
When the MSP updates their pipeline template, all client pipelines automatically update on the next run — zero manual maintenance.
How It Works
Git-based configurations flow through Azure DevOps pipelines to your M365 tenants.
WhatIf Preview
See exactly what will change before deploying. Review, approve, then apply with confidence.
