Data collection to improve Outlook 2013 performance with Office 365

Summary
Starting with the August 2013 update of Microsoft Outlook 2013, Microsoft is collecting additional information from client computers that connect to the Office 365 service. This information will help the Office 365 team identify client connectivity issues and resolve them faster. The goal is to greatly improve the health and performance of the Office 365 service. The following are examples of the kind of information that is collected:
  • The time required to process a request with Office 365
  • The time required to retrieve free/busy information from Office 365
  • Details about unsuccessful connection attempts made to Office 365
The Office 365 team is focused on continuous improvement of all aspects of the Office 365 service to make sure that our customers have a great experience.
