Change microphone for Word/Outlook Dictate only (Win10)?

I can setup my recording device in Windows 10 under Sounds. This is the microphone taken for Dictate in Word and Outlook.

However, I want to use 2 microphones (e.g. one for Zoom, and a 2nd one for Dictate). I have found that there should be an option to individually select those per application, but neither Word nor Outlook is visible there for me.

Any alternative I can use?

Using advanced sound options from Sound Settings, then:

Some programs show here, but unfortunately NEITHER word NOR Outlook 365

No idea why GADWIN shows here, but not Word 365.....

Slightly related to my question here: Windows 10 speaker sound (voice) to text?

Solution 1:

As I know, this is impossible, we could not change the sound input and output devices separately for the Outlook program. I did wanted to change Outlook reminders sound to a specific audio device before, but could not make it. Sounds like what you want is similar as what I tried before.
