Using New Outlook on Windows for professional communication and productivity
Hello Joan Sarty (LCL),
Welcome to the Microsoft Community.
I understand that you mentioned being unable to send or receive emails in the new Outlook.
Is this email a Microsoft domain email or a third-party email? You can tell me the domain name after the @ symbol.
First, you can check if it works normally on the corresponding service provider's web platform. For Microsoft domain emails, log in to Outlook.live.com.
If there are any related error messages, please let me know.
Best Regards,
