I've checked on my original email address with the provider and the new
address is not linked or part of my account. It is independantly set up with
the provider.

The recipients see my original email address. What I'm not understanding is
that this address is no more in my Outlook email account.

Is a solution to uninstall Outlook then re-install?

Uninstalling and reinstalling won't help. As I said, your recipients will see
whatever address you specified in the "E-mail Address" field of the account.
If you're replying to older messages that you received via the old account,
then Outlook will try to reply using that account. If the account doesn't
exist, the replies will remain in the Outbox and shouldn't get sent unless you
specifically choose the new account, but then the recipients will see the
address you've defined in the new account. Open your Sent Items folder and
add the "E-mail Account" field to the column headers to see what account
Outlook used to send the message. Perhaps that will help track down the
issue.
