Using New Outlook on Windows for professional communication and productivity
To ensure I fully understand your situation and provide the most effective assistance, I’ll need a few additional details.
Could you please confirm whether you're looking for steps to add the account to New Outlook, or if you're receiving an error when trying to add it?
Additionally, may I know the email domain (the part after @) and whether you're trying to add the account for the first time?
In the meantime, you could refer to the following Microsoft article for steps on adding an email account to Outlook for Windows: Add an email account to Outlook for Windows | Microsoft Support
I look forward to your response.
