I currently have my own work email setup on Outlook. All good.
We also have a distribution list that users send questions to and those emails are distributed to me and a couple of other guys. The email they send to for support is in the same domain.

My question is, how can I reply from Outlook and it looks to users as if it's coming from the email that they send questions to rather than my own domain account?

I have access to the exchange system so can make necessary changes to the distribution list if necessary.
