How to set Outlook 2013 -> File->Options->Mail-> Message Arrial settings through SDK?

Question

I want to change below settings using outlook api.

I am using Visual Studio and outlook intercom library.

Is it possible to change these settings. I have referred this SO question Change Outlook settings using VSTO.

Answer 1

There is no programmatic way to read or set these options, but they are stored in the registry. You can set them directly, but Outlook would need to be restarted.

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Outlook\Preferences]
"PlaySound"
"ChangePointer"
"ShowEnvelope"
"NewmailDesktopAlerts"
