Scan Outlook by using Microsoft Support and Recovery Assistant


Microsoft Support and Recovery Assistant scenarios aren't available for new Outlook for Windows.


Microsoft Support and Recovery Assistant use advanced diagnostics to report known problems and details about your Microsoft Outlook configuration. Reported problems are linked to public-facing documentation (usually a Microsoft Knowledge Base article) for possible fixes. If you're a Support professional, you can review customer reports that are generated in HTML format.

The scenario in the Assistant that is described in this article replaces the Outlook scanning functionality that was originally provided by the Office Configuration Analyzer Tool (OffCAT).

For more information about the Assistant, see About Microsoft Support and Recovery Assistant.
