Microsoft Teams – Data Storage Diagram

by | Apr 2, 2018 | Collaboration

If you haven’t figured out already, Microsoft Teams uses existing O365 applications in the background to provide mail, chat, and file management functionality.   But where exactly is the data stored?   We recently had a prospective client ask this exact question.  Their concern was driven by the need to meet content governance compliance rules in their industry.  They wanted to use the capabilities of O365 Security and Compliance, but first, they needed to understand where the data is stored.

Teams uses a variety of O365 features.  These include:

  • Exchange – provides the email address for the team and calendar functions
  • Skype – provides the persistent chat features

This data was accumulated from our own testing and the following Microsoft resources:
