Hello! My name is Sandy.I'm reviewing your question now. Let's get started!
May I connect with you remotely (over secure network session) to check/fix the issue directly?
Secure Remote support($9) can save a lot of time. I will fix the issue while you stay in front of your computer. It is 100% safe and secure.
Once you accept the secure remote support offer, please click the link:
Scroll down on that page and click "I Agree".
Download/allow and run this program to start secure remote session.
Over secure remote session, I will check the webmail account settings, and email client settings.
Have you changed the outgoing port to 587 and checked SSL settings for it?
Please check Date and Time on your computer. Is this correct?
Please reply back to me.
Else, we can continue in the question and answer session, but I will need to ask a number of other questions and try and walk you through some steps.
