    Welcome Ian Kidd,

    Thanks for reaching out to Microsoft Q&A Forum. I understand that emails are being sent to an incorrect address even when you select the correct recipient in New Outlook.

    Could you please confirm:

    • Does this happen with only one recipient or multiple recipients?
    • Does the incorrect email address also appear in your Outlook Contacts?

    In the meantime, you can try these steps:

    1, Check the saved contact:

    • Open New Outlook.
    • Select People from the left sidebar.
    • Search for the recipient's name.
    • Open the contact and select Edit contact.
    • Correct or remove the incorrect email address, then select Save.

    2, Check the recipient before sending:

    • Create a new email and enter the correct address.
    • Double-click the recipient's name in the To field to check which email address Outlook has resolved.
    • If it is incorrect, remove the recipient and enter the correct address manually without selecting a suggestion.

    3, Check Outlook on the web:

    Looking forward to your update.
