V-228449 DTOO253 SV-228449r508021_rule Medium
Description
This policy setting controls what happens when an untrusted program attempts to use the Save As command to programmatically save an item. If you enable this policy setting, you can choose from four different options when an untrusted program attempts to use the Save As command to programmatically save an item:- Prompt user. The user will be prompted to approve every access attempt. - Automatically approve. Outlook will automatically grant programmatic access requests from any program. This option can create a significant vulnerability, and is not recommended. - Automatically deny. Outlook will automatically deny programmatic access requests from any program.- Prompt user based on computer security. Outlook will only prompt users when antivirus software is out of date or not running. This is the default configuration. If you disable or do not configure this policy setting, when an untrusted application attempts to use the Save As command, Outlook relies on the setting configured in the 'Programmatic Access' section of the Trust Center.
