OneLogin - Office 365 Provisioning Fails with "API Not Authenticated for App Office 365 V2" (4383247)

This issue occurs when the OAuth tokens configured in the OneLogin Office 365 V2 application are not authenticated or are no longer valid.

Until the OAuth connections are reauthenticated with valid Microsoft administrator credentials, OneLogin cannot complete provisioning requests to Office 365.

Reauthenticate the Office 365 V2 OAuth tokens in the OneLogin application:

Step 1: Access the Application

1. In OneLogin, navigate to Applications.
2. Open the Office 365 V2 application.
3. Go to the Configuration tab.

Step 2: Clear Existing Token

1. Clear the Office 365 V2 (Microsoft Graph) OAuth token.

Step 3: Authenticate Tokens in a Private Session

1. Open an incognito/private browser window.
2. Log in to the OneLogin admin portal.
3. Return to the Office 365 V2 application → Configuration page.

Step 4: Reauthenticate OAuth Connections

1. Under Office 365 V2 (Azure Graph) OAuth, click Authenticate.
2. If prompted, select the Office 365 V2 account.
3. Sign in using Microsoft Office 365 Global Administrator credentials.
4. After the first OAuth token is authenticated, proceed to authenticate the second token.
   • The credentials may be reused automatically.

Step 5: Retry Provisioning

1. Close the private/incognito browser window.
2. Return to your standard browser session.
3. Retry provisioning for the affected user(s).
