Outlook default email
You can try creating new outlook profile and set your primary email address as default. Basically, whatever email address you set up first will be the default one.

Thanks very much for your message and the suggestion to set up a new Outlook profile. I had a look at the link that you sent regarding this, but I don't clearly understand the ramifications of setting up a new profile with respect to disturbance of my current set-up. Therefore, I'd probably prefer to leave the situation as it is, if there is no other alternative approach to the issue I described.
