What is Outlook.exe?

Microsoft Outlook is a personal information manager that can be used as a stand-alone application, or can work with Microsoft Exchange Server and Microsoft SharePoint Server for multiple users in an organization, such as shared mailboxes and calendars, Exchange public folders, SharePoint lists and meeting schedules.

Overview

outlook.exe executes as a process with the local user's privileges usually within the context of Windows Explorer. It is set to be run when the PC boots and the user logs into Windows (added to the Run registry key for the current user). It has been configured with a firewall exception which allows both inbound and outbound network communication without being blocked. The file is digitally signed by Microsoft Corporation.
