Begin Scanning Microsoft Office 365 Apps
Learn how to connect Microsoft Office 365 apps to Prisma SaaS to begin scanning for security violations.
To connect Microsoft Office 365 to Prisma SaaS and begin scanning files and folders on OneDrive and SharePoint, you need to:
- Ensure that you have a OneDrive subscription. A storage plan is separate from an Office 365 subscription.
- Grant Prisma SaaS access to Office 365.
- Add the Office 365 app to Prisma SaaS, providing Prisma SaaS information about your Office 365 account.
For information on which automated remediation capabilities Prisma SaaS supports with Office 365, refer to Supported Applications with Remediation.
Add Office 365 App
In order for Prisma SaaS to scan assets, you must consent to specific permissions during the course of adding the Office 365 app. Without the requested permissions, Prisma SaaS cannot authenticate (OAuth2) with Office 365 and cannot scan assets, even after you successfully install the Office 365 app.
If you forget to consent to permissions, you can correct the misconfiguration, but it’s more efficient to avoid the issue.
- (Recommended) Add your Office 365 app domain as an internal domain.
- Log in to Office 365 using an account with Global Admin role permissions.Before you add Office 365 app to Prisma SaaS, you must properly establish communication between Prisma SaaS and the Microsoft Office 365 SharePoint app and OneDrive app.
- Go to http://portal.microsoftonline.com and log out of Office 365 to ensure that you are not logged in as a user other than an account with Global Admin role permissions.
- Log in again to Office 365 using an account that has the Global Admin role permissions.
- Add the Office 365 app.
- From the Prisma SaaSDashboard, clickAdd a Cloud App.
- SelectOffice 365.
- Select one of the following:
If you have a dedicated Office 365 account, selectUsing a custom configuration?and provide the URL for OneDrive and SharePoint that are part of your custom configuration.
- Connect to Office 365 Account
- Using a custom configuration?
- Enter the login credentials for the account with Global Admin role privileges on the Microsoft Online page to which Prisma SaaS redirects you.
- Review andAcceptthe permissions requested.Prisma SaaS requires these permissions to scan your assets on Office 365.After authentication, Prisma SaaS adds the new Office 365 app to the Cloud Apps list asOffice365n, wherenis the number of Office 365 app instances that you connected to Prisma SaaS. For example, if you added one Office365 app, the name displays asOffice365 1. You’ll specify a descriptive name soon.
- (Optional) Give a descriptive name to this app instance.
- Select the Office365nlink on the Cloud Apps list.
- Enter a descriptiveNameto differentiate this instance of Office 365 from other instances you are managing.
- ClickDoneto save your changes.
- Start scanning the new Microsoft Office 365 app for risks.
- Select.SettingsCloud Apps & Scan Settings
- In the Cloud Apps row that corresponds to the new Office 365 app, select.ActionsStart Scanning
- During the discovery phase, as Prisma SaaS scans files and matches them against enabled policy rules:
When you add a new cloud app, Prisma SaaS automatically scans the cloud app against the default data patterns and displays the match occurrences. You can take action now to improve your scan results and identify risks.
- (Optional) Modify match criteria for existing policy rules.
- (Optional) Configure or edit a data pattern.
Fix Office 365 Onboarding Issues
The most common issues related to onboarding are as follows:
After you add the Office 365 app, no scanned assets display for Office 365.
Prisma SaaS doesn’t have permissions to access Office 365, resulting in a misconfiguration.
Office 365 app stopped scanning for assets.
On March 2020 Prisma SaaS changed Office 365 app for SharePoint to use Microsoft’s new Graph API to improve performance and supportability (OneDrive already uses Graph API).
Reauthenticate your Office 365 app in order for Prisma SaaS to continue scanning your assets. You’ll be asked to consent to the required SharePoint permissions. You do not need to repeat the onboarding process.
After you add the Office 365 app, Prisma SaaS does not quarantine your OneDrive assets.
You must have a OneDrive subscription. Only then can Prisma SaaS create the necessary
Quarantinefolder on OneDrive and quarantine assets.
Verify that you have a OneDrive subscription.
If you purchase a new OneDrive subscription, you must reauthenticate on Prisma SaaS.
Prisma SaaS stopped quarantining your OneDrive assets.
Prisma SaaS requires the administrator account and OneDrive license that you used to onboard the Office 365 app, for moving assets to the quarantine folder.
After you add the Office 365 app, if later that same administrator account is deleted or the OneDrive license is revoked, Prisma SaaS can no longer quarantine assets.
Verify that the administrator account you used to add the Office 365 app still exists and has a valid OneDrive license.
If the administrator account no longer exists, you must reauthenticate on Prisma SaaS using a different administrator account with Global Administrator role permissions and a valid OneDrive license.
If the administrator account exists but does not have a valid OneDrive license, you must add that OneDrive license to the administrator account, then reauthenticate, or use another administrator account with Global Administrator role permissions that has a valid OneDrive license, then reauthenticate.
Fix Prisma SaaS Access to Office 365
If you forgot to grant the necessary permissions during onboarding, you need to fix this misconfiguration.
- Grant Prisma SaaS access to Office 365 using Azure Portal.Without permissions, Prisma SaaS cannot authenticate (OAuth2) with Office 365 and cannot scan assets, even after you successfully install the Office 365 app.
- Log in to Azure Portal at https://portal.azure.com as Global Administrator.
- Navigate to.Enterprise applicationsAll applications
- Select.Aperture by Palo Alto NetworksSecurityPermissions
- ClickGrant admin consent for.yourOrganization
Office 365 Files Unavailable To Prisma SaaS
By default, Office 365 cloud apps quarantine malicious assets, causing the quarantined file to become unavailable to third-party quarantine capabilities, including those on Prisma SaaS. To provide the high user experience to which you’ve become accustomed, Prisma SaaS UI informs you when your cloud app quarantines an asset.
Prisma SaaS understands that your organization needs to remediate files across cloud apps from a single user interface. Prisma SaaS is working diligently with cloud app vendors to enable third-party remediation of malicious assets.
If you have super admin permissions on your cloud app, you will always have direct access to the assets quarantined by your cloud app, even when Prisma SaaS does not.
Your file does not display in Prisma SaaS and your cloud app notified you that it quarantined the file.
Prisma SaaS does not know that the file exists.
Your cloud app immediately discovered the malware and quarantined it—before Prisma SaaS could copy the file’s metadata and the asset’s contents.
Prisma SaaS copied the file metadata but cannot download a copy of the asset itself for WildFire analysis because your cloud app quarantined the asset, making it unavailable.
Prisma SaaS immediately copied the asset metadata—before the cloud app could discover and quarantine it.

Quarantineoption is unavailable.

Restorequarantine actions on a file initially quarantined by Prisma SaaS.
Prisma SaaS cannot download a new copy of the asset and perform quarantine actions because your cloud app quarantined the asset, making it unavailable.
Prisma SaaS immediately copied the asset metadata, downloaded a copy of the asset itself, and quarantined it—before the cloud app could detect malware and quarantine it.
With WildFire analysis enabled, Prisma SaaS sent your file to WildFire, a malware verdict was returned, and so Prisma SaaS quarantined the asset based on your policy.
After the copy of the file expired on Prisma SaaS or Prisma SaaS received notification from your cloud app that your cloud app eventually discovered the malware and quarantined the asset, Prisma SaaS overwrote the malware status.
As super admin, if you need to download or restore the file, do so on your cloud app.
However, if you want to delete the file, do so on Prisma SaaS—not your cloud app, to enable Prisma SaaS to close the open incident and the quarantined file, keeping Prisma SaaS up to date.
You’re unable to
View Snippetor access any other historical information on a file initially quarantined by Prisma SaaS.
