Vulnerability discussion

If an untrusted application accesses the recipient fields, the application could gain access to sensitive data and potentially change that data. This could result in mail being sent to the wrong party. By default, when an untrusted application attempts to access recipient fields, Outlook relies on the setting configured in the "Programmatic Access" section of the Trust Center. This setting determines whether Outlook will warn users about programmatic access attempts: * Only when antivirus software is out of date or not running (the default setting)* Every time* Not at allIf the "Not at all" option is selected, Outlook will silently grant programmatic access to any program that requests it, which could allow a malicious program to gain access to sensitive information.Note: This described default functionality assumes that the "Outlook Security Mode" Group Policy setting to ensure that Outlook security settings are configured by Group Policy has not been followed. If Group Policy security settings are used for Outlook, the "Programmatic Access" section of the Trust Center is not used. In this situation, the default is to prompt users based on computer security, which is the equivalent of the "Only when antivirus software is out of date or not running" option in the Trust Center, and the user experience is not affected.
