Support and Recovery Assistant is a new tool that helps users troubleshoot and fix issues with various Office 365 apps and services. The app diagnoses common Outlook issues like account setup, connectivity issues, password issues, or Outlook stops responding or crashes. To identify the root cause of these issues, the app runs checks such as:

Checks licenses
Verifying users’ credentials and that Office 365 servers are reachable
Checks for updates to Outlook clients
Checks authentication
Network checks
Protocol checks

Depending on the test results, the tool can offer to automatically fix problems for users or provide instruction on recommended solutions. All the diagnostics results are saved in a log file for users to share with their Office 365 admin or support engineers for further investigation.
