Turn on external sharing notifications for OneDrive for Business

To help your OneDrive for Business users monitor and control which external users have access to their files, make sure external sharing notifications are turned on. Owners of OneDrive for Business files and folders will be emailed when:

  • Another user invites external users to shared files

  • An external user accepts an invitation to access their files

If external sharing is enabled in your Office 365 environment, these notifications are enabled by default.

Note: Office 365 admins can use auditing to monitor content that is shared externally.

Turn on external sharing notifications

  1. Open the OneDrive admin center and click the Notifications tab.
