Unable to Send Emails
Starting today, I cannot send an email either via Thunderbird on my Mac (MacOS Montery 12.4) or using the mail app on my iPhone. I can receive emails. If I use the Outlook app on my Mac or the browser, I can send and receive emails. My outgoing settings are: Outlook.com smtp.office365.com 587 xxxxxxxxx@outlook.com Normal PW STARTTLS
My ISP is COX and there are no virus programs
Thanks so much.
