This issue was so frustrating as I was being told that it was a Microsoft Outlook problem. I finally got a computer services person to come in and look at it. It is not something wrong with my router/firewall. It is not something wrong with my IP/helo address. It is not a Microsoft problem. My computer services person and I tried every configuration we could before finally studying the very last sentence of the error message we had been getting. (Excessive failed authentication, ESMTP server temporarily not available). Could that mean that they had flagged my account because I had tried and failed to send emails too many times? We wondered! So we called customer support to ask if that was the case and were told no. We escalated to a second tier support person and we were told no. We kept asking if they would just reset my account. We escalated to a next level support person. He said there didn't look to be a problem on their end, but because were so insistent (we might have gotten a little heated with him), he agreed to reset or whatever they do. That worked! I can now send emails in Outlook. They take forever, though, in some cases, 24 hours. I'll keep working on my issue to see if it gets any better. I don't know if this will work for anyone else, but I thought I would send the info along.
