Hi Bob Barnes,
I understand how confusing this can be, especially when the mailbox works correctly on Outlook on the web and another Microsoft account downloads email normally on the same PC, while this specific address does not.
I’ve reviewed the Q&A Assist reply already posted in the thread, and its overall approach is appropriate for determining whether the issue is related to the local Outlook (New) app rather than the account itself. If you haven’t had a chance to try those steps yet, please let me know the outcome. To avoid repeating the same points, I’d like to add a few targeted observations that are often relevant in this scenario:
- Since another Microsoft account works as expected in Outlook on this PC, this strongly indicates an account‑specific sync or local app data issue, rather than a general Outlook installation problem. In such cases, removing and re‑adding only the affected Hotmail/MSN account can sometimes refresh its sync state more effectively than reinstalling Outlook entirely.
- With New Outlook for Windows, sign‑in and synchronization rely on locally cached app data. Fully signing out of Outlook, closing the app completely (ensuring it is not still running in the background), then reopening it before adding the account again can help refresh the authentication token.
- As a comparison check, if possible, try adding the same account to Outlook (New) on another Windows device or user profile. If it works elsewhere, that further confirms the issue is isolated to this PC’s local Outlook data.
Just to make sure this is interpreted correctly, when you mentioned the email ID was “just created on this PC,” can you confirm whether that means the account was newly added to Outlook on this computer, rather than the mailbox itself being newly created?
Given that the account was originally created about 15 years ago and used successfully in the past, this behavior would not be related to mailbox provisioning, but instead points to a local Outlook (New) sync or profile issue on this device.

I hope this helps clarify the next steps.
