Hello! SteveC2023
Thank you for the reply
That's good news! We are happy that the issue has been resolved and it got resolved by reverting back to the Windows Mail app instead of the New Outlook for Windows. So, it would seem that it can be that the issue is within the supported email domain since New Outlook for Windows is still very new and still improving its usage and performance for all users.
If you have any suggestions, feedback and ideas please feel free to share them in: Send feedback to Microsoft with the Feedback Hub app - Microsoft Support for the New Outlook for Windows, as our developers will continue to improve the application.
To help other customers searching for help on related issues, please feel free to mark the response you found most helpful by clicking “Yes” on the bottom of that post.

Thanks again for choosing Microsoft!
Sincerely,
Vince
