Office 365 support and Recovery assistant repairs office

The Office 365 support and Recovery Assistant automatically identifies the cause of the problem by executing the built-in test process, which helps the user automatically resolve many common problems or prompts the user to manually troubleshoot the failure. Although the tool is currently focused on the fixes and processing of Outlook common problems, it can be automatically updated to get the ability to troubleshoot and resolve new failures.

If SaRA does not automatically fix the problem, it automatically suggests the next steps and assists you in contacting Office 365 support engineers.
