SetDeliveryTime allows users to set default values for the "Do not deliver before" parameter in Outlook.
Current version: 1.0.4
The application is a COM add-in that only works with the classic desktop version of Outlook for Windows.
It is not compatible with the new Outlook for Windows.
To confirm your version: If you see File on the top-left of the screen (menu bar or ribbon), you're using classic Outlook. If File is missing (e.g., you see a simplified ribbon or sidebar), you're using either the new Outlook for Windows or Outlook on the web.
