OneDrive Connector Setup
Index OneDrive files by creating a dedicated App Registration with the appropriate permissions.
Setup Checklist
Before starting, ensure you have:
- Azure Global Administrator or Cloud Application Administrator role
- Microsoft 365 E1+ licensing for OneDrive content
- Certificate generated (see Certificate Generation Guide)
- Active Atolio deployment
Required API Permissions
Step 1: Create App Registration
- Navigate to Azure Portal > App Registrations
- Click “New registration”
- Enter name:
Atolio OneDrive - Select “Accounts in this organizational directory only”
- Click “Register”
Step 2: Add API Permissions
⚠️ Important: Only add Application permissions, not Delegated permissions
- In your App Registration, click “API permissions” in the left menu
- Click “Add a permission”
- Select “Microsoft Graph”
- Click “Application permissions” (not Delegated permissions)
Add these Microsoft Graph permissions:
Identity & Directory Permissions (Required for ACL mapping)
Application.Read.AllGroup.Read.AllGroupMember.Read.AllUser.Read.AllDirectory.Read.All(optional)
OneDrive Content Permissions
Files.Read.AllReports.Read.All(required for indexing progress display)
Step 3: Grant Admin Consent
- After adding all permissions, click “Grant admin consent for [your tenant name]” at the top of the API permissions page
- Confirm by clicking “Yes”
- Verify all permissions show “Granted for [your tenant name]” with green checkmarks
Step 4: Upload Certificate
- Click “Certificates & secrets” in the left menu
- Click “Upload certificate”
- Select your
.cerfile (not the.pfxfile) - Add description:
Atolio OneDrive Authentication - Click “Add”
Step 5: Collect Configuration Values
From the “Overview” page, copy:
- Application (client) ID
- Directory (tenant) ID
You’ll provide these, along with your base64-encoded .pfx certificate and its password, as listed in Required Configuration Values.
Required Configuration Values
Enter these values in the Atolio Admin console (v4.24 and later), or send them to Atolio Support (your Deployment Engineer).
| Value | Where to find it | Example / format | Secret |
|---|---|---|---|
| Directory (tenant) ID | Step 5, App Registration Overview page | GUID, e.g. 00000000-0000-0000-0000-000000000000 | No |
| Application (client) ID | Step 5, App Registration Overview page | GUID, e.g. 00000000-0000-0000-0000-000000000000 | No |
Certificate (base64-encoded .PFX) | Certificate Generation, the base64 output of the .PFX file whose .cer you uploaded in Step 4 | Long base64 string | Yes |
| Certificate password | Certificate Generation, the password set on the .PFX file | Your chosen password | Yes |
Keep secrets secure: Share values marked “Yes” in the Secret column only through a password-manager share (e.g. 1Password) or another secure channel agreed with Atolio Support. Never send them in plain email, chat, or support tickets.

resources:
group:

excluded:
- contractors@example.com
Optional Settings Example
These optional settings go in the same block as the Configuration Example, under common: and configuration:. This example shows optional settings for OneDrive, including a sync schedule and resource filters:
