You expect Office to be secure and work properly. To meet this expectation, we collect diagnostic data as you use Office which helps us find and fix problems, identify and mitigate threats, and improve your experience. This data does not include your name or email address, the content of your files, or information about apps unrelated to Office.
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 does not contain your name, your email address, or any content from your files. All diagnostic data Microsoft collects during the use of Office applications and services is pseudonymized, as defined in ISO/IEC 19944:2017, 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 an Office application crashes, certain details about the crash, that help us to diagnose and fix the problem, are collected.
For more information about required diagnostic data see Required Diagnostic Data in Office.
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 remediate 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. 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 Office, or later by visiting the Account Privacy settings of any Office app.
For more information about optional diagnostic data see Optional Diagnostic Data in Office.
Using Account Privacy to choose your diagnostic data setting
Important: This applies to Microsoft Office version 1904 or newer.
In any Office application:
Go to File > Account > and under Account Privacy select Manage Settings.
Select the level of diagnostic data that you're comfortable with.
Note: If you're using Office with a work or school account your administrator may have configured what settings you're able to change.
