Unbelievably frustrating.
Following all of you advise but still no progress.
I am at Method 3: Manually set up Outlook. at section 'o' when I click ok I get an error message saying
"the proxy server you have specified is invalid. Correct it and try again." I have copied this exactly form the help menu - it is correct.
Not sure what else I can do. I'm pulling my hair out.
