Microsoft uses the following data classifications when implementing data protection policies. 

Personal data is any data that relates to an identifiable natural person, such as a name or contact information. This can include user IDs that a Microsoft service assigns to a user, although this is considered pseudonymous, as it cannot alone necessarily identify an individual. 

Administrator data is the personal data and contact information about individuals that sign up for Microsoft services. The administrator data also includes aggregated users' information and other data associated with the administrator account. 

Object metadata is the setting data associated with all Microsoft services that you sign up to. This includes Azure storage account details, virtual machines, SQL databases and their tables, columns, headings, and forms. This does not include the personal administrator data. Customers should not include personal data, or other sensitive information in object metadata, because object metadata may be shared across global Microsoft systems to facilitate operations and troubleshooting. 

Payment data is the information customers provide when making online purchases with Microsoft. It may include a credit card number and security code, name and billing address, and other financial data. Microsoft uses payment data to complete transactions, as well as to detect and prevent fraud.

Support and consulting data is all data provided to Microsoft by, or on behalf of, a customer, typically in a support scenario, or when engaging Microsoft professional services. This data may be in any form, including text, sound, video, or images, and even software. The data may be acquired via phone, chat, email, or webforms.
