Microsoft 365 Onboarding
This guide walks you through connecting your Microsoft 365 environment to Chronom using the onboarding wizard. Once connected, Chronom will analyze your M365 licenses and identify optimization opportunities.
For manual setup or CLI-based configuration, refer to the Azure App Registration guide — M365 uses the same Azure AD App Registration mechanism.
Overview
Microsoft 365 integration uses an Azure App Registration with specific Microsoft Graph API permissions to read your license and usage data. The onboarding wizard guides you through creating the App Registration, granting the required permissions, and connecting it to Chronom.
Step 1: Select Microsoft 365
On the Select Connection Type screen, choose Microsoft 365 and click Continue.

Step 2: Create an Azure App Registration
Even though you're connecting Microsoft 365, the connection is made through an Azure App Registration in your Microsoft Entra ID tenant.
Chronom displays the App Registration details you need to create:
- Name:
Chronom Read-Only App Registration - Supported account types:
Accounts in this organizational directory only (Microsoft only - Single tenant) - Platform:
Web - URI:
https://app.chronom.ai

Click Go to Azure to open the Azure Portal and create the App Registration using these values.
For a detailed walkthrough of the Azure Portal steps, see Create a New Azure App Registration.
Once created, return to Chronom and click Next.

Step 3: Setup Access in Azure
Enter the credentials from the App Registration:
| Field | Where to find it |
|---|---|
| Tenant Name | The name of your Azure/M365 tenant |
| Tenant ID | Entra ID → Overview → Tenant ID |
| Client ID | App Registrations → your app → Application (client) ID |
| Client Secret | The secret value created in the next step |

Click Continue when all fields are filled.
Step 4: Create a Client Secret
Create a Client Secret for the App Registration in the Azure Portal. Follow the link to Docs at the bottom of the screen, or refer to Step 3 of the App Registration guide.

Click Next once the secret is created.
Handle your Client Secret with extreme care. Only share it through Chronom's onboarding wizard. Chronom will never ask for it via email or any other channel.
Step 5: Assign Permissions
Grant the App Registration the Microsoft Graph API permissions required for M365 license analysis:
| Permission | Type | Purpose |
|---|---|---|
User.Read | Delegated | Basic user profile access |
Directory.Read.All | Application | Read directory data for license mapping |
Agreement.Read.All | Application | Read organizational agreements |
AuditLog.Read.All | Application | Read audit log data |
Reports.Read.All | Application | Read usage reports for license optimization |
Sites.Read.All | Application | Read SharePoint site data |
TermStore.Read.All | Application | Read term store data |

Click Our Docs for step-by-step instructions on granting these permissions, or refer to Step 2 of the App Registration guide.
You must click Grant admin consent in the Azure Portal after adding all permissions. Without admin consent, Chronom cannot access M365 data.
Once permissions are granted and admin-consented, click Continue.

Step 6: Permission Verification
Chronom automatically verifies that all permissions are configured correctly.

If successful, you'll see:
All permissions verified! Everything looks good. You're ready to continue.

Click Continue to proceed.
Step 7: Set Scan Frequency
Choose how often Chronom scans your M365 environment.

Select a frequency from the Scan Frequency dropdown and click Continue.
Step 8: Procurement Details (Optional)
Upload previous invoices or Microsoft enterprise agreements to help Chronom customize license optimization insights.

- File Upload — Drag and drop or click to upload. Supported formats:
pdf,docx,xlsx,csv,txt,png,jpg(max 3 files). - Custom Pricing Instructions — Enter any special pricing notes, EA terms, or volume licensing details.
Providing your Microsoft Enterprise Agreement or invoices helps Chronom accurately calculate potential savings based on your actual pricing — not list prices.
Click Continue (or Skip) to finish.
Step 9: You're All Set!
Chronom has started analyzing your Microsoft 365 environment. You'll receive an email notification when the analysis is complete.

Click Continue to enter the Chronom dashboard.
