Connect Office 365 to Microsoft Cloud App Security

This section provides instructions for connecting Cloud App Security to your existing Microsoft Office 365 account using the app connector API.

Cloud App Security supports the legacy Office 365 Dedicated Platform as well as the latest offerings of Office 365 services (commonly referred as the vNext release family of Office 365). Cloud App Security does not support the Legacy Microsoft Business Productivity Online Standard Suite.


In some cases, a vNext service release differs slightly at the administrative and management levels from the standard Office 365 offering.

Cloud App Security supports the following:

  • Office 365
  • SharePoint
  • OneDrive
  • Teams (only appears after activities from Teams are detected in the portal)
  • PowerBI (only appears after activities from PowerBI are detected in the portal, and requires you to turn on auditing)
  • Exchange (only appears after activities from Exchange are detected in the portal, and requires you to turn on auditing)

How to connect Office 365 to Cloud App Security

  • You must have at least one assigned Office 365 license to connect Office 365 to Cloud App Security.
  • Exchange administrator audit logging, which is enabled by default in Office 365, logs an event in the Office 365 audit log when an administrator (or a user who has been assigned administrative privileges) makes a change in your Exchange Online organization. Changes made using the Exchange admin center or by running a cmdlet in Windows PowerShell are logged in the Exchange admin audit log. For more detailed information about admin audit logging in Exchange, see Administrator audit logging.
  • Exchange Mailbox audit logging must be turned on for each user mailbox before user activity in Exchange Online will be logged, see Exchange Mailbox activities.
  • If Office apps are enabled, groups that are part of Office 365 are also created in the specific Office apps, for example if SharePoint is enabled, Office 365 groups will be created in SharePoint.
  • You must enable auditing in PowerBI to get the logs from there. Once this is enabled, Cloud App Security will start getting the logs (with a delay of 24-72 hours). If your Azure Active Directory is set to automatically sync with the users in your Active Directory on-premises environment the settings in the on-premises environment will override the Azure AD settings and use of the Suspend user governance action will be reverted.

After connecting Office 365, you will see data from a week back including any third-party applications connected to Office 365 that are pulling APIs. For third-party apps that weren't pulling APIs prior to connection, you will see events from the moment you connect Office 365, because Cloud App Security turns on any APIs that had been off by default.
