You expect Microsoft 365 to be secure and work properly. To meet this expectation, we collect diagnostic data as you use Microsoft 365 and OneDrive which helps us find and fix problems, identify and mitigate threats, and improve your experience. This data doesn't include your name or email address, the content of your files, or information about apps unrelated to Microsoft 365 or OneDrive.

Under your control

There are two levels of diagnostic data: Required and Optional.

Note: Diagnostic data may contain "personal data" as defined by Article 4 of the European GDPR, but it doesn't contain your name, your email address, or any content from your files. All diagnostic data Microsoft collects during the use of Microsoft 365 applications and services is pseudonymized, as defined in ISO/IEC 19944-1:2020, section 8.3.3. 

Required diagnostic data

Required diagnostic data is the minimum amount of data that we need to collect in order to keep the product secure, up to date, and performing as expected. For example, if a Microsoft 365 application crashes, certain details about the crash, that help us to diagnose and fix the problem, are collected.  

On the Mac the Microsoft Automatic Update is one example of a service that has to collect required data in order to keep the installed Microsoft software -- such as Edge, Defender, Intune, Skype for Business or Remote Desktop -- up-to-date. For example, if a software update didn't complete successfully we need to be able to troubleshoot that issue.

For detailed information about required diagnostic data, see Required diagnostic data in Microsoft 365.

Optional diagnostic data

Optional diagnostic data is data you can choose to provide, this data helps us make product improvements and provides enhanced information to help us diagnose and fix issues. For example, learning how long it takes a thumbnail version of a PowerPoint slide to render so we can improve the performance of that feature.

Optional diagnostic data may also be used in aggregate to train and improve experiences powered by machine learning, such as recommended actions, text predictions, and contextual help.

If you choose to send optional diagnostic data, it is collected in addition to required diagnostic data.

Optional diagnostic data requires your consent, and you may enable it while installing and setting up Microsoft 365, or later by visiting the Account Privacy settings of any Microsoft 365 app.

For detailed information about optional diagnostic data, see Optional diagnostic data in Microsoft 365.
