I am using Outlook for Mac v. 16.6. I have always had my cox e-mail installed in Outlook and it worked fine. When I upgraded my Outlook with my new computer, I re-installed my cox e-mail. I am able to receive e-mails but not send. I have called customer service, but after checking the setting in my Outlook, they said that they couldn't help and that I would have to use the online portal to send e-mails. I was a little dumbfounded since Outlook is a major e-mail program that obviously other people are having issues with. Can you help?
